Honda Accord Fuel and Fuel System Questions

    I don't know the answer but be careful when running that low. Typically, fuel pumps are in the gas tank and the gasoline is used to cool it - run too low and you stand the chance to damage the fuel pump.

    The rated capacity is 17.1 gallons. The light will usually come on at about 13.5 gallons on my 03 Accord (same size tank). Do you actually want the car to run out of gas for some reason? 17.1 minus 13.5 would be 1.6 gallons, so for my car I could go about another 40 miles easy, after the light comes on. It's nice to know how far you can safely go, if you're particular what kind of gas you want.

    I set my B trip meter to 0 when the E light comes on. The best I've done is 60 miles after the light come on.

    I think you mean 3.6 gallons.

    Thanks Mrbill, hit the wrong number. :(

    The fuel capacity has been 17.1 gallons. Possibly before 1990. My 1996 is 17.1 as well.

    Just wondering... where'd the 15.4 gallon idea come from?

    I got the 15.4 gallon capacity from 2006 Honda Accord brochure. Any info. in the owner's manual?

    I recently filled up just as the light came on and only put in 13.6 gallons. This leavs 3.5 as the reserve.

    The owners manual states that there is 2.7 gallons left once the light comes on plus a small reserve amount. Seems like that small reserve is .8 gallons to make up the 3.5.

    In city driving there are too many variables, so I would probably just fill up before the light comes on or shortly after. On the highway, where I know what my mpg is, I may push it a little and use up 1 or two of the reserve gallons - leaving at least 1.5 gallons.

    Of course 2 gallons at around 35+ mpg is 70+ miles - that is a long way to drive with the light on, and may be hard to do psychologically.

    Just came back from a trip to D.C. The empty tank light went on and I drove for another 25 miles. When I filled up the tank, I put it 14.5 gallons. So I still had about 2.6 gallons left in tank, including the 0.8 gallon reserve.

    So the reserve means: it cannot be used at all. As a result, only 16.3 gallons of fuel can be sucked out of the fuel tank. If for highway driving, it convert to almost 500 mile range (16.3 x 30mpg).

    Interesting. My brochure listed it as 17.1 gallons. The CR-V however just might be in the 15 gallon range, but I'm not certain. The owner's manual will confirm the 17 gallon figure, but I can tell you firsthand that I've put over 15 gallons in my car before in a fillup (ran with the light on for about 60 miles).

    Car and Driver and Motor Trend (as well as for that matter) will have the info you are looking for, but ALWAYS check your manual and take it as the last word.

    06 and 07 Accord fact sheets list the fuel tank capacity as 17.1. My 06 owner's manual lists it as 17.09 (P. 266 and very last page).

    Does anyone know where this relay is located? I have been told only the mitsuba relay is a problem. If the relay is a denso it is ok. Seems like you shouldn't have to give your vehicle up for a half day if you have a relay that does not have to be replaced.

    Under dash fuse/relay box, bottom far left.
  • How common is it to replace a primary O2 Sensor on a Honda SE 2002? I have had to replace mine for the last 2 years> Luckily, the first replacement was under warranty but the second one wasn't almost exactly one year later.
  • I just bought a 1986 Honda Accord. It was running fine for the first week, but then it cut off while i was in traffic. i was able to get it started again a couple hours later, but only after giving the fuel tank a few whallops and putting the gas all the way to the floor. it's started a few times since then, and i was even able to drive a little ways without it cutting off, but now it won't start at all. i put some marvel mystery oil in the gas, and then it started giving me problems shortly after that. (coincidence? i'm not sure). i put some fuel injector cleaner in it two days ago, but to no avail.
    what should i do to get this hunk of junk moving again?
  • If hitting the tank was your actual fix, then I'd say you looking at a new fuel pump.

    I've seen tow truck drivers come to a call, get out, wack the fuel tank, and have the owner try starting their vehicle again. When it does, he smiles, hands them their minumum trip charge, and drive away.

  • thanx mrbill. i came to the same conclusion with my stepdad about two hours ago. i'm about to look on ebay to see if i can find one.

  • I have a 1990 Honda Accord that normally runs great. I just got it a couple months ago and haven't had any real problems with it. Now I have a problem: I was on "E" , and gas prices being what they are, I decided I would use a 2-gallon gas can with what smelled like gasoline to get me where I needed to go. This is where the problem comes in: I have no clue what that mystery liquid was, but after about 5 minutes of normal driving, the car started to chug. I made it about 2 miles, shut the car off, then tried to restart it, with no luck. Can someone please tell me how to get my car running again?

    The three possibilities the mystery liquid could be are kerosene, deisel, water, and or watered down gasoline.

    These are some things I know about whats going on:
    The car is getting spark
    fuel treatment didn't work
    the fuel pump is working
    Someone please help me

    my 86 accord idles rough,tries to run out of gas on a hill at times,have to pump pedal to keep it going. also on highway if you hold it to floor goes to 4-5 grand & starts cutting out like a rev limiter.i seen on here it could be the coil not sending enough juice to the fuel pump.any other ideas.also does anyone know what the vacuum diaphram on the drivers side of the carb. controls? thanks
  • Anyone know the actual fuel capacity of the 1984 honda accord lx hatchback? my owners manual says 15.8, but i have ran this thing almost dry and can only put about 11 gallons in it. I just bought it recently with 86k on it, great shape, just cant get the fuel econony accurate due to the tank size issue.

    Thanks for any info
  • elroy5elroy5 Posts: 3,741
    You don't have to know the size of the tank, to figure mileage. do it this way. 1) Fill the tank (stop pumping at the first click) 2) reset the trip odometer (before you drive off) 3) drive till the low fuel light comes on (or when ever you like) 4) Stop at the same gas pump as before (if possible) and fill the tank again 5) Before you drive off !!!!, note how many gallons it took to fill the tank (from the gas pump), and how many miles are on the trip odometer. 6) Divide the miles by the gallons to get miles per gallon. Example: 380 miles divided by 13 gallons would equate to 29.23, or a little more than 29 miles per gallon.
  • thegraduatethegraduate Posts: 9,731
    Elroy is exactly right. Tank size is completely irrelevant to determining actual fuel mileage. Use that method (I do) and you'll get accurate mileage, assuming your odometer reads correctly.
  • well, sure I understand that formula, and have used it, however my main concern is the actual capacity of the fuel tank, I was hoping there was some standardization and that someone could let me in on it.
