I have plenty of fuel system, so no worries there. It was set up for turbo d ls2 but now going na. Dual walboro 450s in a ricks tank. I ll prolly just wire up the 1 pump n leave other one in there. -10 feed, -8 return

60lbs injectors would be pretty spot on and you can always bump up the duty cycle up to 90% (nothing over 90 though) if you need some extra fuel, email me if you have anymore questions or if you would like a quote on AUS injectors.
