For starters you might need a fuel regulater.and or you might have to check the tank and see what kind of pressure it sends.

I did this on a mustang 5.0. I had a 190 LPH fuel-pump, and the stock fuel-lines for EFI. I left them both alone. IT never had an issue even shifting at around 7K rpm. (huge cam, etc.) Never fuel-starved the bowls.

Every fuel-system is different. Just dialed the FPR down to 10-12 I believe it was. It didn't burn up the pump because it was a return-style fuel system. no harm, no foul.
