P.S. Who is supplying 4500psig ? I know some of the cascade filling systems have a 5,000 psi tank to top off , but it is suposed to be limited to 3800 psi delivery pressure.
At 4500 psi ,the rupture disk on the honda factory tank is real close to that. It would be a bad day at the office it it blows out!!!
Cheers.
Apparently EGR valves have become quite complex since the last time I bought one for $12 and fit it to the top of my '66 Mustang. But it set me back in my seat. (Circulating exhaust gas costs what? And why, if they burn so clean, does anyone worry about a GX have one of these at all? But alas, mine was not to question why. Mine was but to pay or die.)
Any of you experienced similar EGR problems? The car recently started hesitating and power loss going up hills is clearly evident (probably due to miss-firing). Tech says that if the EGR is bad, the computer gets bogus info from its blown brain, maps the fuel incorrectly and misfires result.
Any insight from you guys?
While talking to him (and he was a font of wisdom, a very nice guy) he explained that the 1999 GX only has one fuel filter. You shut off the gas, run the car till it stalls, then access the filter by pulling down the protective cover and open the bottom of it (the filter) with an Allen-wrench to drain off any excess condensation every 7500 to 10000 miles. Let is drip out, button it up, and you are good to go.
He explained that later model GX's (2001 forward he thought) have two fuel filters.

Usually that pump gives me right around 3600-3700psi, but once I filled in Diamond Bar (SCAQMD) and the Techs were tweaking the system, took 3 tries to fill, and got 4,000psi. I was concerned, but they said it was fine.
I have gone 193 miles, 23 with light on, and had 500psi left in tank, took 5.5gge.

I love it that I dont have to visit gas stations anymore!
Free fuel will be dispenced to any CNG vehicle that attends and there will be give away items to commemorate the event. In attendance will be: SoCal Gas, NGV America, Gas Equipment Systems Inc, AQMD, Clean Energy, numerous NGV owners, Honda Corporate Alt Fuels Division, and more. We will have Los Angeles and local Press there to interview owners, so we hope to see you there.
I've been working on this project for almost a year and a half and I'm really excited to bring this station to the public. Robertson's Honda is opening new frontiers and making news around the world. This will open the way to more dealerships offering this service to the public.
I hope that, in spite of the mid week date, that some of you can break away from your busy lives and help us show the press that we are a group of people trying to make a difference in the world. The more exposure we get, the more people will want them, buy them, and therefore provide an economic basis for more stations.
If you're traveling on the 14 freeway through the Antelope Valley, don't forget to stop in and say hello!
Address and Phone are posted in my GX groups in Yahoo groups> Civicgxtalk, and Civicgxngv. Stop in and say "Hi."

The temperature of the fuel is raised as it goes into the tank (simply by virtue of the turbulence established as it rushes into your tank). More heat, less fill. The same is true of the fast-fill holding tanks at your favorite station. If they have been repeatedly depleted, they won’t have quite the compression they might otherwise deliver.
Regarding manuals for the Honda GX. I found out who Honda’s OE publisher is. You can find everything they print www.helminc.com I am not sure if they will allow non-dealers to order (but I have been told they will). Products include the full factory service manuals for the GX, traditional owners manuals (and GX supplement), there is even a five CD set of Honda training material specific to the GX. Don’t know what is on them, but it sounds interesting. They do ALL of Honda's manuals.
Today I talked to a guy in Tulsa who has developed a vehicle-to-vehicle CNG refueling hose. Unfortunately, it won’t work unless one of the vehicles using the hose is set up with proper isolation and venting valves to relieve pressure inside the hose after it has been used. Not a cheap solution, but far cheaper than building a stand-alone spare gas tank. A cool idea compliments of Tom at Tulsa Gas Technologies. That said, most of us would be better off with AAA Plus for towing.
Apparently, Mercedes-Benz has a dedicated CNG car for European distribution with a five-gallon “limp home” gas tank on board. Now that IS a fine idea.
The procedure for draining requires shutting off the fuel supply by turning off the emergency shut off valve behind the driver's side rear tire. Let the car run until it stalls out. Remove the plastic liner and use an allen wrench to take out the drain plug. Let it leak and then put it all back together.
I tried to do mine today, but I need to figure out how to remove the fasteners holding the plastic protective cover in place without damaging them.
They have the little hex screw in the middle, but they don't seem to unscrew. Can any of you help?
Good luck on the opening of your new cng station. I called up there last December looking for a shoreline mist GX. I had to go elsewhere because you did not have one, but you guys were well informed and helpful. We now have 2 GX's. What great cars. We are using Phill. If I were not going out of town, I would make the drive up there (from Santa Monica) next week.

The plug will blow out at approx 250 deg. f. and release all the gas in about a minute. The fittings and lines will take 6000 psi no prob. Not the tank. This is nothing to play games with !
The 2 Full lines on the gauge are 3,000 and 3600 for the second one. Approx.
I used to regularly fill my tank at 4500 psi (even though it was a 3600 nozzle...nothing wrong with the gauge) and the most it would ever take close to empty was 6.5 gge. You don't need to worry about the tank...lol. They can take much more pressure than 4500. There was a movie about these tanks and one of the things I remember was that the pressure relief valve will not blow until close to 8000 psi. They put it in a 1700 degree fire and it didn't blow the valve until it reached almost 8000 psi. Also, they can take a 100 mph head on crash without losing any of its integrity. They are a heck of a lot safer than gasoline or propane! Oh, and when I had my Toyota Celica on cng/h2, a world-renowned hydrogen expert told me that I could use the same tank for 5000 psi hydrogen without any problems...you just have to change the fill nozzle.

I had it done in Mesa, Az at ALT FUEL SYSTEMS,INC. by Darrel Essary (www.altfuelsys.net). I had the larger tank installed in the backseat(over 500 mile range now) for just over $1,050 + tax, and that included a $250 wood-carpeted shelf cover. He also will install an extra 5gge tank in the trunk for $750 + tax.

need some advice here. i have a 2003 gx which just hitted 55k miles last week. two days ago, i decided to have the valves adjusted for the first time since the manual recommends adjusting them every 30k. the problem started yesterday on the way home from work. there's a strange vibrations or shakings when i accelerate the car under 30mph, and sometimes during idling WHILE THE CAR IS IN GEAR (no problem during idling while in park or neutral and rev up engine in park/neutral). the vibrations/shakings are more noticeable while a/c is on. and no shakings/vibrations felt above 30mph. so my questions are: could this be the cvt or engine mount problems since it happens only when it is in gear? could this related to the valve adjustment i had done? if i decide to take it to a honda dealer(in LA or OC area), which dealer is more experienced on the GX and who should i talk to(adviser or technician)? is there an independent shop that specializes in CNG with CVT transmission in the san gabriel valley area? thanks for reading.
That being said, I do not believe your problem is related to the cng system ,so any Honda dealer or other qualified mechanic should be able to find the trouble. Just keep it away from "Spiffy Lube" , "Sleezy Lube" , "Oil Shop" and all of the other places like that for anything other than an oil change.
The cvt is still used on gasoline hybrid civic models, and was also used on the gasoline HX from 98-2001, and was used on the Insight. All Honda dealers have experience with cvt issues.
Any idea what this car would be worth? I am having no luck figuring it out using normal sites like KBB.
"They have the little hex screw in the middle, but they don't seem to unscrew. Can any of you help?"
First, I think you meant up until and INCLUDING 2000. ('98-'00) Second, those are "clips" that you have to pry off with a special tool (it goes around it similar to the claw on a hammer). Then I'm sure you saw the screws also holding it on. I changed mine after 118K miles getting the manual supplement from helminc.com. Since I had used very clean fuel up to that point (99.9% pure methane/hydrogen) it wasn't really that dirty. The filter cost $36 from Honda and $25 from AutoZone, but I went with Honda on the advice of the AutoZone salesperson. The plug is tightened to 20# and the canister 30#. Hope this helps.

Took the car back to the dealer (Garff in SLC). They messed with it for a while and claimed bad injectors. Wanted me to spend $560 each. I told them that DCH Honda in Temecula will sell them to me for $200 less each(internet price). But instead of doing that I mailed the set of to Five0Motorsport.com. These guys know injectors. They've done a fair amount of GX injectors. They cleaned them up using their ultrasonic process, flow tested them and reported back that only one was dead. The rest were fine. Total cost $144. Ordered one from DCH. Hopefully this solves the problem. It has been a little frustrating.

A word of warning. According to the service manager at Garff Honda in Salt Lake (the only GX rated dealer in Utah), "we've tried this and seen the fix fail." But the guy in Tulsa that told me about fiveO swears by them. Uses them all the time. My guess is that it depends on who does the work. FiveO specializes in injectors. It is all they do. They’ve been in business a long time. Something tells me they would not be if they constantly got complaints that the “fix failed.”
I want to buy another GX or two. Anyone know of any 1999 or 2000 GXs for sale?
I just had 2 injectors #1 and #2 replaced 2 weeks ago at 95k miles with Cerritos Honda. #3 injector was bad at 45k miles, #4 turned bad at 70k. Last 2 was covered by emission warranty. This time it is not in warranty and Honda dealer wanted a total of $1700 for two injectors. I complained to American Honda that my injectors dies every year. Honda said they found no recall or TSB on my injectors. Luckily Honda finally agree to help me with part of the total repair cost. The injector which costs $600 retail (ouch!), now costs $400 each. I got away with 2 new injectors and 2 new injector covers and a smaller but sizable bill.
I did my maintenance and replaced the CNG filter but still unable to prevent injectors from dying.
If any of you had this problem, please complain to American Honda. If there are enough incidents they might issue a TSB or recall.
Call Honda customer relations (800) 999-1009
Maybe next time I would rebuild them instead like you did.
Then today I looked at a 1999 with 67k at a used dealer in Tujunga ca (north Los angeles ). Car was from texas , no plates. It ran ok ,but had that " Been worked on" look. Bottom of engine had antifreeze all over. I think it has head gasket problems. The a/c was also not working.
This car is currently on e bay . be careful.
My take on the injectors. The 01 and later have a spin on secondary filter ,and I have never seen any posts on 01 and later injector failures, but the cost to change it at the specified 10k interval is very high. Part is $87 on the internet and $125-$149 at a honda parts counter. It looks like an oil filter with a heavy shell.
It might be protecting the injectors, but over the life of the car, the cost will add up to more than a new set of injectors.
Looks like a case of pay me now , or pay me later, but you will pay!
Hey Honda : Cut the price of the filter and us owners will buy more often and you will still make money!
Murphy
I never got my plates, so I called/e-mailed repeatedly and finally they found the paperwork.
They told me they needed me to smog it because it was over 90 days, and they would reimburse me.
Well after repeated e-mails and phone calls I never got my money for the smog.
Initially I was happy with the deal, but I would not buy another car from them.

By the way, I'm new here, but you guys are full of a lot of great info. Thanks.
I wanted to see if anyone could give me input as to whether or not these wheels would fit the 2006 GX?
Thanks in advance,
-Eddie
For example, my 1991 Dodge came with 195/70-14 tires, but an alternate size listed on the door sticker was 205/60-15 (which of course required new 15 inch wheels). These two tires have the same outside diameter so the speedometer and odometer would read the same.
195/70-14 OD in inches = (195 mm)(1 in/25.4mm)(0.7)(2) + 14 = 24.74 in
205/60-15 OD in inches = (205)(1/25.4)(0.6)(2) + 15 = 24.69 in
The 205 tires are of course 10 mm wider, but the wheel well could accomodate this. It was an officially recognized alternative tire. You would have to check with a Honda dealer to see if the tires from the EX will work on your GX.
clearly, once they've slapped in some components, then others no longer make sense (such as gasoline delivery system for a GX) ... but wheels/tires aren't an issue. they would only potentially be an issue if you were getting them from a previous generation Civic or other vehicle ... then those specs are essential to know.

Anybody have recommendations for mechanics (Honda dealer or otherwise) with good knowledge about both CNG and CVT in the CA bay area? Saw that somebody was posting bay area fuel prices on the pricing thread, so figured there must be a few other bay area GX owners. Shops to avoid would be great too, if you feel comfortable posting that. Thanks!
The ride, to my surprise, is actually SOFTER than with the stock 15" tires!
I assume that your new tire/wheels are 205/55-16 89H on 16 x 6.5 inch alloy wheels. The nominal unloaded OD of these is tires is 24.88 inches.
And I assume that the old ones are 195/65-15 89H on 15 x 6 inch steel wheels. The nominal unloaded OD of these is 24.98 inches.
So the new tires are 0.41 % smaller in diameter which is insignificant as far as speedometer and odometer reading, but the larger width and lower profile should give a significantly improved handling, not to mention appearance. Narrow tires on steel wheels are substandard nowadays.
This change could possibly produce a decrease in fuel economy, which might also be negligible, or it might be as much as a 3 or 4 % decrease. Let us know if you find a difference. Of course, you could reverse this difference by driving even a few mph slower on the hwy.
The original tire/wheel combo was probably picked to favor fuel economy and lower price over handling because the GX is mainly sold as a fleet vehicle and a green vehicle. The original tires would have less aerodynamic drag (narrower profile seen from front) and lower rolling resistance due to their being 65 series and maybe the tire model was one of the low rolling resistance models.
What tires/wheels did the owner of the EX change to? What is the maximum inflation pressure of your old and new tires? What pressure do you plan to keep the new tires at? What is the make and model of the old and the new tires? What are you going to do with the old wheels?

If you do an overnight fill, I'd guess you could possibly get another 10 miles out of it, but that would reeaaaaaallly be stretching it.
