Ford F-Series Fuel Pump/Fuel System



  • My problem is that during driving, the truck acts like it runs out of fuel. Tank has gas. let the truck sit usually over night, and it will start. I have change the fuel filter many times, also pick up pumps and HP pump, no junk in tank. any ideas
  • Does your check engine light come on when that occurs? If you shut your truck off after that and then turn the ignition key to ON does the fuel pump not run for a short time like it should?

    The symptoms you described and the things I listed describes how my truck acted. Talking to people and reading up on it pointed me to not consider the ECM box -- that the ECM box hardly ever goes bad, but, after running into many deadends I eventually got a rebuilt ECM from O'Reilly's and it has been running like a top -- again.

    Not saying that is what you are dealing with -- just want you to keep your mind open to that possibility. God luck.
  • The rear fuel pump just doesn't come on.
  • i have a 1995 ford F150. the front fuel tank pump died and i want to remove the fuel from that tank. i bought a self priming transfer pump but i can't seem to get it working. does the tank have a stopper or what am i donig wrong?
  • Hello, I have a 1989 F150 with the straight 6 engine that has over 260,000 miles on it. The truck has always run well but I'm now having a problem with what I think is the fuel system. The truck will sometimes stall and run rough like it is running out of gas, and eventually quit. If I sit for about an hour, I can get it running again and it will run fine for a few days, then the problem repeats itself. I've replaced the fuel filter a couple of times and a mechanic has checked the fuel system pressure, but is unable to diagnose the problem. I'm not comfortable driving the truck now and would like some suggestions from anyone out there as to what the problem may be. Thanks, Mike
  • Your Ford runs on 30-40 psi of fuel pressure. Using rubber fuel hose and clamps would be fine. Using the plastic lines is only safe if it is mounted on the inside of the chassi rail to protect it. Good Luck.
  • I have the hard plastic gas line and front tank connection went bad. The part is discontinued so can anyone tell me how to blank off the line so the truck will run on rear tank. I have tried plugging the line and clamping it to no avail. Thanks
  • You din't specify year make or model but it doesn't really matter, Fords are pretty similar. First your only dealing with about 30-35-40psi of fuel pressure.

    Depending where the line broke depends how to do the fix. Autozone sells a mending kit for those lines that come with the new quick connect ect. If the line is damged or leaking, the easier fix would be to repair that section. If it is a return line, you can also bypass the first tank all together with a sutible size tee, rubber fuel line and clamps. If you choose to do the bypass, just make sure your splicing into the same type of fuel line on the other tank..,return or outlet. If you specify where exactly the line broke, or if it is the tank fitting itself, and more info on the type of vehicle and fuel system, such as does it have a selector valve ect. Any way hope this helped, good luck.
  • The truck is a 1990 F150 extened cab. The break is at the front tank quick connect. There is a y in the line about 12 inches from the break and it travels back to the front the rear tank. The front tank has never worked so I just need to cap that line that used to go to the quick connect at tront tank. Thanks for the help.
  • Thanks for explaining it better. My recomendation is to buy the repair kit that will put a new quick connect end on the broken line. Then either reconnect it to the tank, or put a fuel filter on the end of the new quick connector. This will allow you to put a large vaccum cap and clamp on the other end of the filter to cap it off and keep it from leaking. This will also make it easier in the future if you decide to reuse that fuel tank and some point. Good luck with it.
  • Thanks for the help. I will let you know how it works out.
  • I'd also like to know how it works.
    Thanks Stan 58

    have a 92 f150 8' bed with two tanks. need to remove the front tank pump-sender. does anyone know if this is possible without removing tank. looking at this seems possible, but do not know if length of unit will come all the way out.thanks.
  • There is only two ways to remove the fuel pump assembly. Dropping the tank down or lifting the bed up. The fuel pump assembly and hanger is about 11 inches long and fragil. Do it the right way.

    Here is the trick. Drain the tank of fuel. Use motor cycle straps to secure the tank in place while you remove the two tank straps completely. Motor cycle straps almost work like a pully so you can lower the tank down slowly to undo fuel lines ect without breaking them. Good luck with it.

    I have a 1994
    f150 - trying to replace the rear gas tank. But I don't know how to disconnect those fuel lines. there is a clip on the lines themselves right in front of the gas tank and I have removed, does the lines then just pull apart?
  • Ford uses 2 types of clips, metal and plastic. If you have the metal ones you have to use the disconect tools to release them. If they are plastic, you simply depress the 2 white in color tabs inward at the same time and tug on the line.

    My '07 F-250 message center is showing "WATER IN FUEL", this is my first diesel so I am ignorant to the maintenace and repair. Can someone help me with this message. From reading some of the posts I understand there is a drain on the filter, where is it, should I use some sort of dryer in the fuel?
    Thanks in advance

    or Diesel Supplement on how to drain the water seperator.

    PS, if you waited for the message to come on, you waited 2 long. You should check your water seperator monthly at least.

  • Rick here from Miami Fl. I just finished installing the front fuel pump in my 94 F150. I had to remove the drive shaft and the tank, cause the pump sits on top of the tank. my truck has two tanks also and on the inside of the cab by the plastic kick plate by the drivers side and passangers side are two reset switches for the fuel pumps. you may want to check this.

  • I recently replaced the front tank fuel pump on my 94' F150. after installing it, I turned the key on without starting it, and the pump would run for about 4 or 5 seconds then turn off. telling me that it got up to pressure. after a few days of trying to trouble shoot why it's running rough, I noticed that now the fuel pump dosn't stop. just sitting in the drive way I've wasted about a 1/4 tank of gas. lots of black smoke and black soot all over the floor. I removed the 20 Amp fuse to the fuel pump and it idles perfect. can the pump be over pressurizing, hence the pressure regulator be bad? There are two what I call top hats, they look like a 1 to 1 1/2 inch silver can thats in-line with the incomming fuel line and one in the loop that feeds the injectors. which ione of these is the fuel pressure regulator?
