1995 ford F250 4x4 7.5L After driving for an extented period of time, it starts lugging and acts like it is running out of fuel. the first time it did it , it started rightup when I switched fuel tanks , so I figured it was the in tank fuel pump then it did it on the other tank also. after a few min. it started right up and ran ok. this has happened many times . I replaced filter.and fuel pressure regulator. thought that was the fix .it ran well for a couple of days then started doing it again. I can here both fuel pumps build pressure when I cycle the ignition. It always starts back up [so far ] after a few min. and may not act up for 20 or 30 miles ??????????
A couple of things that you might want to check. When the truck feels like it is starving for fuel, remove the gas cap from the tank you are selected to and see if there is a vacuum in the tank.
Another possibility is that there is debris in the fuel tank that is building up around the pump intake. There usually is a sock filter there that can get blocked. I had this problem on one vehicle and it gave the symptoms you describe.
You may want to also look into the fuel reservior that switches between the tanks. I think your 95 7.5 has a different setup than my 87 but same symptoms existed in mine. It was a $140 dealer-only part but fixed the problem.
Have tried all suggestions with no luck I do appreciate the feed back . I took it into Ford dealership and they could not find anything. It is not giving any codes. Looks like I may have to look into the clunker buy out Thanks everyboby that responded. DLG
