Truck starts idles and drives fine. Until at highway speeds it seems to have a slight fuel "cut" or miss. I have a receipt for raptor lift pump and reman vp44 from 10/2009. Truck is an 01 mostly stock. No fuel pressure gauge. Any help is appreciated.

Have you had it checked for codes?

My raptor pump has a pressure regulator on the pump. Try cranking up the pressure if it does. I had the same issue with my truck. Which is when I got the raptor. It fixed my issue.

 

The only codes it throws are tranny codes from the swap. And ill check it later this afternoon
