Re: Fuel Pumps

Re: Fuel Pumps
I've got the Airtex pumps - been running for 7 seasons now (about 30k mile).
I DON'T recommend them since when I changed them, one was DOA out of the box (bad check-valve). (Make in China). However, I WILL say that they maintain pressure at ~54 psi at WOT with an LT5 making 432 rwhp (FWIW).

Re: Fuel Pumps
I believe the standard and Airtex run about 189 LPH/50GPH these will run about 320/87 GPH, also going to clean the injectors out
