Archived fuel issue

[SteveFarley]

Ok I am sure most will think I am nuts but I seem to think I am having some sort of fuel issue. I have had 25-30 PSI of fuel pressure since I added my pusher pump well lately I have had 20 and can pull it down to 15 or so WOT. I could never get lower then 25 before. I seem to be lacking power also it has its moments where I think right on it better but then it goes away. I changed the fuel filter today nothing. I had a bigger set of injectors in for awhile but took them out because of a very huge ( 5mpg loss) and I gained a miss and stalling issue shortly after then were in I took them out and that went away????



Any help would be great thank you SD

What year of truck do you have? The VP44 also has a return line. You may be having trouble with your injector pump.

you might want to check the filter inside the tank. diesel fuel tanks will biuld up sludge over a period of time. this sludge can clog up the filter/strainer on the pick up tube inside the tank.....
