    The fuel filter will not affect mileage. If there is no check engine light then there is nothing wrong with the engine or trans, check tire pressure, check your driving habits, do you jack rabbit from stops or change lanes allot and so on.

The fuel filter should be located on the inside of left frame rail. It is an inline filter that may require a "quick disconnect tool" to remove. Bear in mind that the fuel line remains pressurized with the engine and key off, so take caution when removing the filter. As far as lowered fuel mileage is concerned, along with the suggestions from emissionwiz, you may try a tune up and or replacing the air filter. Hope this helps.

My Ford F150 engine stopped running at low RPM.. I wonder if it's bad gas? Clogged Fuel filter?


The first thing to check is the Fuel pressure at the Fuel Injector Rail schrader valve. You can get an inexpensive test kit at Harbor Freight. The pressure should be between 28 and 45 psi with the engine running. If it is lower than that you can replace the filter. If that doesn't cure the pressure problem then the pump is next.

A common problem with Ford products built in the 1980s is the ignition module mounted on the distributor.
You will need to figure out if it is a fuel problem or ignition problem to proceed.

Very,very heavy on gas


Change the air filter, the fuel filter, and your oxygen sensors (the oxygen sensors are the main sensor used to compute the air/fuel mixture going into your engine). Also, check and adjust your tire pressures. On your car you should run about 36psi in each tire. Low pressure will kill your gas mileage.

POOR GAS MILEAGE


Have you changed the fuel filter? I know it sounds weird but a plugged filter will make a truck use more gas. The computer tries to compensate for less fuel by commanding the injectors to open longer. Also a plugged filter will cause excess back pressure on the fuel pump making it loud.. Good Luck.

Ford pickup truck with fuel starvation


I would try a fuel addative or stablelizer, it might have some moister and sedament in tank from setting so much, or just old gas, try that, if that don't help than you will need to chg. the filter because it may have got in there and is restricting the flow of gas, hence poor excelaration. You can also can take it out on a clear stretch of road and open her up and blow the cobb webs out of it, it might just be carboned up too.

Gas mileage dropping


While changing all the filters and things, did you change the fuel filter? It could have just been poor quality fuel which can be caused by getting fuel from the bottom of the barrel so to say. If the station you got the gas at was getting low there is a chance that there was water in the fuel. Normally this would cause the vehicle to run a little bit rough, but not always. I would run another tank of fuel through it and see what you get on a second tank.

Ford 150 gas mileage issues


Your O2 sensors may be freaking out. The O2 sensors tell the ECM how much fuel to send through the injectors. When the O2 sensors quit working right, the ECM has no idea what to do with the fuel. Do a fuel pressure test as well. If the pressure regulator is working correctly, it'll go through alot of fuel as well. You should be at 40 psi. When running you should be at 37 psi.
