Cruising home from work the other night at 60mph the truck lost power and the fuel filter light came on. I backed off and the light went out but I couldn't go over 50 or the light would come back on and the truck would stumble. Fortunately I carry a spare filter in the back so I pulled over and change filters. Truck ran great for 2 days and then it happened again. I suspected the tanks went foul so I dropped them and took a look. They were both clean as can be, except for the broken pick-up tube pieces. I put new pick-ups in and changed the filter again. Same story! Anyone experience this one before?

I had the same problem a few months ago and had to have the truck towed to Ford.

They never found the problem.

Might have been a grounding issue from what they tell me. Hasn't hiccupped since.

Check your fuel pump........

Take the Schrader valve core out and hook a hose and pressure guage to the outlet.........crank engine see what you get for pressure, should have 4-6 psi from a good lift pump.

Volume test same place hook a hose to it crank over the engine 10 seconds you should get 1/3 pint of fuel minimum or 1 pint at 675 rpm in 30 seconds... engine running

Important the fuel shutoff solenoid (FSS) wire on the IP should be disconnected if you do not want a start just cranking. Re connect FSS after test complete.
