Fuel req

I´m having problems with my fuel supply

I´m in 400rwhp range and installed a 255l walbro but it still sputtering at high rpms,i´m going to buy the hotwirekit but how much hp can the stock fuel lines and FPR support?

I have a new dristribuitor and compleate ignition system so it´s not the cause of the sputtering

36# injectors, I'd assume you'd be fine. Stock lines I'd only worry about with over 800hp, but I'm just guessing.

Check your fuel filter?

I know, I was reading your sig

Best I can offer would be trying 50psi.

You are not tapping out the lines or regulator. The hotwire kit is something you should have done already with the pump but I suspect the problem will continue after you get that done.

not nearly everyone have the hotwire kit and are running fine,so it depends on each application

I´m suspecting the FPR is not holding pressure,getting a gauge to measure it
