Can i run returnless style on a return style fuel system?
So i recently upgraded to a 5.7 ls6 in my 2000 silverado with a return style fuel system..i have it rigged with a t fitting in the feed line that goes to a fpr then to the return line. Is this good enough? my fuel pressure runs around 58-60 psi but idk what it runs a wot...my injector duty cycle is 97% at wot. im running a set of stock 28.8# ls6 injectors.. Am i running out of injector or is my rigged up return style fuel system not supplying enough fuel??
