The last couple months my truck seems to be loosing fuel pressure. Lately I have been watching it alot and it seems to range between 49 and 58 psi depending how hard i'm leaning on it. My truck is a '99 RCSB with a whipple charged 4.8 in it and a set of LS1 heads and a LS1 cam. It still has all the Whipple Craptronics on but am getting ready to delete all that junk. I just got a set of 44 lb injectors and want to make sure the rest of the fuel system is allright before installing them.

What fuel pressure are you guys seeing and what do you think i should seeing?

 

You will need a new fuel pump or pump booster to keep up with those injectors and boost.

 

What kinda pump do you recomend? How many dollars am I going be be spending on the new pump? Where is the best place to get it?

Any one else know anything about this?
