Hello, I have a few questions pertaining to the Stinger fuel rail and 95+ injectors. Last year I maxed out my Stinger deka 80lb injectors or fuel system, walboro 255lph in-tank pump, Paxton factory style fuel pressure regulator, and factory lines, at 99% duty cycle. Does anyone know if the walboro pump and stock lines can support 80lb up to 95-100lb injectors and the Stinger rail. Also, if I upgraded the rail, AN lines, fuel sump, and larger pump, would the fpr adapter block and factory style fuel pressure regulator flow well enough to not have increased fuel pressure issues at idle with less demand for fuel or should I just buy a new regulator as well? Thank you.

Stock lines will support around 500whp running gasoline. If the Walbro is wired so it gets full alternator voltage then it will support about the same power. With stock type wiring it will barely get to 400hp.
I can't say for sure if the regulator would flow enough with a larger pump or not. I know it would if you controlled the pump via pulse width modulation so it's not running full bore at idle/cruise. That also makes the pump last longer, and doesn't heat up the fuel so much.
