new problem

[kicker139db]

Just change the fuel filter and bleed the air out. Now the truck fall flat at 2500rpm. It didnt do that before the fuel filter. What could my problem be? Its a 1993 "F" Thanks.

I'd bleed the fuel filter again, to see whether any air is finding its way into the fuel filter housing.

Do you have fuel coming out of the bleed hole with lots of pressure (shoots a couple of inches up in the air) --- That just happens to be the rpm mine (1993) will do when the lift pump dies. Check that you didn't knock the wires off the oil pressure switch. Oil pressure switch sends a signal to lift pump to work.
