my truck, aftermarket fuel pumps, any out therefor this crap non return fuel system??????

 

Nothing specific.... I know of one truck that has duel factory pumps in the stock basket. I was considering the same setup using an Aeromotive rising rate regulator and Aeromotive fuel lines for the 5.7 . Any inline pump will help out. I see you have an '03 like me. I swapped for an '04 pump to raise the fuel pressure up to 58psi. (from 48)
