hi guys - i have a 2004 5.3L silverado 4x4 with a pro charger p-1sc 8lbs boost & 44lb injectors . engine is running very lean & i know that I could burn a piston if i don't get more fuel. so i'd like to put in a areomotive 340 in tank pump to get the fuel I need . but witch one do i use & how do you install the pump i don't think they come with instuction LOL .and one last thing . i have a returnless fuel system .putting in this new pump will give more fuel .what happens if it makes too much fuel ?? where does it go ? it my seem like a stupid question . i'd just like to know before going though with it ! any info or pictures will be a great help

thanks

 

The regulator is in the tank module. It should bypass enough at times of low fuel consumption. As far as instructions im not a full size guy but I shoe horned 2 walbro 255s in a colorado with minimal drama and no instructions

 

two things you can buy one is a kenne bell boost a pump or meth

 

i did the walbro 255 and i love it. easy install and it does what i need

 

I used the center in center out, and it is just as easy as the walbro to install. I would suggest to make it return style with boost reference, since u have a procharger.

 

great advice -thanks to all of you ! it's going to take a while to get the setup in. but I will let you know what happens... thanx
