Hey all, I have made a post in the past about my fueling issues and a couple of things have changed since then.

I now have an Aeromotive 340 fuel pump with Racetronix hotwire kit.

I have a brand new stock FPR I just installed, and I am still only able to get 30psi at the rail. The entire FEED system of the fuel system is -6AN nylon braided line, the return and purge system are all stock lines.

I can not for the life of me figure out why I am not getting the 50psi the truck requires.

Application:

03 Silverado with 02 5.3 return style fuel system.

Here is the previous thread if anyone wishes to reference it.

Please let me know if you have any thoughts or ideas, thanks!
