hi there im new here I have a question for you guys I just installed 2 walbro pumps 400 lph like 2 weeks ago and this is my 4th time removing the bed of my truck for fuel issues, they turn on but they are not strong anymore they just push a little of gas they are not pushing hard like the day I Installed them ,do I need any kind of harness or different fuel pump set up since I have a returnless system, I have 2008 sierra single cab 4.8 the reason im doing this is cuz im going boost and this thing is killing me I will appreciate any tips thanks!!

Adding regulator and return off returnless rails
I'm having a similar issue ... my 04 silverado ss .. nnbs intake and returnless rails on tops of my tsp built 408 ... everything is built for boost and after a year of playing on motor finally putting boost to it ... want to be around 15psi ... my question is how did u do ur return .. I've already gotten a spare bucket assembly and installed my walbro 450 ... I really need a parts list for doing all 8an lines and fitting from pump to rails then rails back the a boost referenced reg. Then back to the tank using the old feed line out as my new return in

Shoot an email to Racetronix. They're pretty knowledgeable. They knew what fittings and hose type I would need for the corvette filter setup. Even offered to assemble and pressure test it before they ship it out. I think theyre in canada, so shipping was a short wait.
