The fuel filter and the fuel filter pressure regulator are the same part on the 1988 Dodge Ram 50 Pickup. This part is located in front of the gas tank next to the fuel pump.
the fuel filter is located behind and above the fuel tank filler neck
you tell me
Sounds like a fuel filter problem so I would first check all filters in the fuel system.
The most common reason for you to lose fuel crime, in your Ford F1 50 pickup truck, is a fuel leak. A faulty fuel pump can also cause the problem.
50-60psi key on engine off, 45-60psi key on engine running
50% chance - Fuel pump is goin bad 50% chance - fuel line clogged (check fuel filter)
Every 40 or 50 thousand miles
Clogged fuel filter, air filter, or a fuel pump going bad. ckeck and see if you have water in the filter, if you do you need to drain the tank.
Could be a fuel filter or fuel pump is weak. Change fuel filter and check output pressure of the fuel pump at the Schrader valve on the fuel rail. You will need a fuel pressure gauge. At idle you should be getting at LEAST 30 to 50 psi.
Plugged/dirty fuel filter Plugged/dirty air filter Maybe it is time for a good tune up.
The filter at the bottom of the pump unit is a strainer, and there are actually two of them in there. The main filter is held on top of the pump unit by a clip and also acts as a fuel pressure regulator. The fuel filter/regulator is reckoned by Jeep to be a lifetime filter. The only reason for changing it is if the anti drainback valve has failed within it, allowing fuel to slowly drain back into the tank causing a long crank problem at cold starts. The filter/regulator is available on eBay for around $50.
