Hey,
Ive been asking questions on here concerning a lack of turbo response. All answers provided by the users of this forum have been considered and checked. I am still looking back at the symptom of lack of black smoke when all seemed well with the truck. Used to romp on it and great response and lots of black smoke pouring out , now when I romp on it the response is less and the black smoke is notta. Ive been looking for air inlet leaks , etc. Anybody have these problems and have a good starting point on the fuel delivery. I have already checked and replaced the fuel filter.

 

Fuel pressure/volume might be the culprit, but it also could be a biased sensor as well.
What you really need to do is get some guages, a copy of Auto Enginuity and start a proper diagnosis before you begin to throw parts at it.

 

OK,
Ive got two questions for ya . Where does a person connect a fuel pressure guage on my fuel line? What are the symptoms of a fuel regulator going bad?

 

Follow the steel fuel lines coming out of the starboard side of the fuel filter housing to the cylinder heads. Note where they go in and go to the opposite end of the head and find the little square head NPT fitting that is blocking off the opposite end of the fuel rail. 1/8" NPT threads. Get your fuel pressure there. Right front corner of the engine is the easiest one to get at.
Symptoms of a failing fuel pressure regulator (very rare) are low fuel pressure at all times, even at idle.
Symptoms of a failing fuel pump, clogged filter, clogged fuel pickup screen (much more common) are good fuel pressure at idle and then it drops off as soon as you put a load on the engine and fuel demand goes up. The only way you can read it is with a fuel pressure guage on a long hose and you driving the truck. Too many people just check the pressure in the driveway with the engine idleing, see that it's ok and move on to something else. They miss the true cause of thier power loss because of improper diagnosis.

 

Ok,
Is there a fuel pressure regulator screen on my 2001 7.3 ltr motor? Its location is on the right side of the fuel body , standing in front of the motor ?

 

No screen, that is the older body style that had the mechanical fuel pump only.
The fuel pressure regulator is that bulge and the pipe that it goes into is the fuel return line back to the tank.
