SOURCE: fuel pump location 1988 ford econoline

Theres 2 pumps one in the tank, lift pump, and one in the chassis rail under the driver side. The one in the tank is cheap, the one in the rail is not. The one in the tank only produces low pressure to prime the main pump and if it is broken, may not cause that much of an issue except when starting. the one in the rail is a no-start if it fails. The idea is that the rail pump can supply high pressure for the injectors, so a fuel pressure test at the injector rail will determine which pump is playing up. Hope that helps Tim

If you hear the relay click, but no pressure at all then it would be the fuel pump needing replacement

SOURCE: fuel shutoff switch switch location on a 1988 ford

The fuel pump inertia switch that shuts off the pump in the case of an accident or impact is located under the right side of dash I have also
found them behind the right kick panel. There is also a fuel pump
shutoff relay under the hood on the left firewall, and a relay on the
right fender apron behind a plastic cover. Hope this helps.

SOURCE: Rear Fuel tank doesnt work so my 1990 ford f 150

Hello
Having worked for Ford for 25 years and having seen this very same problem (fuel flows between tank and overflows) many times there is only one cause of the fuel flooding the other tank, the fuel switching valve on the frame rail under the truck is detective, this valve contains special silicone rubber poppet valves that open when the front or wear tank fuel pump is selected, it then seals when the tanks electric pump is shut off at the selector switch, your poppet valves are leaking, all to a common problem. Back in 2000 when I retired this switching valve was no longer sold by Ford parts, it is obsolete. I suggest you check with Ford to see if it is available from some other source or call a local parts store like NAPA or Carquest and inquire is anyone in the aftermarket has them. The last choice is a used one, but of course it could have the same problem as yours as age and deterioration of the rubber valves is what makes them leak.

Fuel pressure


Well most engines have a mechanical pump on the engine, but the E350 models used for motor homes and box vans also use an electric pump in the tank. The pressure rating is still 5-8 psi like the mechanical pumps.
Have you replaced the inline filter ?

My truck has 2 gas tanks, I try to swich the tanks but it only sucks gas out of the rear tank it doesn't matter what the selecter is on what could be the problem?


I have an '87 Ford F150 just like it and have the same problem too. Most likely the front fuel tank's internal fuel pump is not working. The selector switch sends power to the fuel pump in the selected tank, which then pumps fuel to the high pressure pump mounted on the frame ahead of the dual fuel reservoir also mounted on the frame.

How many fuel filter are on a ford f 8000 with a cat motor


I am going to guess that you have a 3208 cat in that truck. The fuel
filter could be either a single or duel setup, with a dual filter they
are usualy side by side(primary+secondary) and most often mounted with a bracket to the fire wall or frame. Connected to the
injector pump with braided hose. The single should be mounted
close to the pump.Also check the line back to the tank, if you have
dual tanks, go to the one with the standpipe or feed tank.(the one with the lines coming from the top of the tank) Somone may have
put in an inline filter. If this information is for repair and not maintenance, that engine has an electric fuel shutoff in case of
low oil pressure or overheat. I hope I was of some help.
Good luck.

1987 f-150 dual tanks fuel problem


You are right. There are three pumps. It sounds like the transfer pump in the front tank is bad. The in tank pumps just supply the high pressure pump to keep it primed. You need the front pump.

My '88 Ford E-150 van (dual tanks) ran out of gas. Now it won't restart with either tank. How do I re-prime the system?


the easiest way is to take off the air filter top, and have someone turn the engine over while you SLOWLY (like out of the air hole in a gas can) pour gas into the carburetor (carefully...) have them press slightly on the gas pedal. It could take a couple minutes of pouring, but It will prime the gas lines. Stop when it will run on its own

F150 dual fuel tank problem


I have to say i'm only guessing, but it sounds like the valve that switches the flow of gas from one tank to the other must be sticking part way open, or bypassing or something, and anything your engine doesn't require, is being returned to the front tank, instead of the rear.
