Default 1985 Ford 150 w/302 EFI

Greetings, my dadís ford has had problems before with fuel pressure regulators, and a module on the distributor, ignition coil, etc. Now when you are going down the road 55mph it starts acting up, like it is running out of gas. If you press the pedal to the floor it takes a few seconds but it will clear up for a short time period, then it will start doing it all over again. I thought it could possibly be the fuel filter.... but that seems too easy. I changed it 2 years ago and the vehicle has maybe 8K miles on it since then. I greatly appreciate any information.

Does it have dual tanks?
If so there is a second filter inside the fuel tank selector valve / reservoir.
It's located down on the frame rail behind the high pressure pump.
You will have to remove the skid plate to get at it. Unscrew the base of the reservoir to replace the filter.

Ford states that the filter is lifetime part but I had to replace it 2x before finally replacing the whole valve with an electric switch valve. I also put a generic filter in each fuel line. My real problem is that a bad sender pump in the rear tank was sending junk through the lines - replaced all that too.

In my case I could not go over 50 mph at which point it would start sputtering and act like it was running out of fuel. At the same time the main fuel pump would whine. Below 50 it would be fine.

I thought 86 was the 1st year of the EFI engines?

Prior to EFI was CFI, had that on an 85 302 Cougar. Don't remember myself when EFI, actually its was called SEFI (sequential electronic fuel injection) was introduced or which vehicle. Back to thread starter, 2 years is a long time on a filter, especially one that doesn't drive much.

Default 1985 F150 w/302 EFI?

Thanks guys, I will start with the fuel filter. I am not positive.... it might be an 86 model. I sincerely appreciate all the help I get from the "techs" on this site. You have saved me $$$$$ and headaches. Once again; Thank You!

Since we last talked, we have changed the fuel filters (the canister and the inline) changed Distributor Cap, and the fuel pressure regulator. The truck, when going a steady 45 mph feels like it is running out of gas. If you press the gas pedal down a little more it quits acting up? Thanks again for any information

Any codes being thrown? Another no expense trial and error, disconnect and plug the vaccuum line to the EGR and test drive. If an ohm meter is available, check the resistance of the TPS as you sweep is thru its range.
