92' 4.9 fuel system problems
my truck keeps wanting to bog down when i hit the gas and it also has a large lack of power. ive been told that it could be my fuel pressure regulator, my fuel pump or my furl filter clogged. i changed my fuel filter and it didnt help. if it was my pump going out on me wouldnt it have gone out by now? its been doing this for 2 weeks and before it started hesitating it would have slow starts where i would have to turn on and off the key a few times to pressurize the fuel system. now it does both.

I dough the fuel pressure regulator is bad unless you had fuel in the vacuum line to it.
You still need the gauge to see if anything is wrong with the fuel system.
Most of the time this problem is the TPS and you need to check it with a analog VOM.
But the TPS may not show up when you run the codes.
What you need to do first is see if you have any hard codes or any codes stored in CM.

Gas in the vacuum line to the FPR means you have a bad FPR.
The TPS mounted on the throttle body.
