IP Full Load Adjustment Procedure for the MW and M pumps
I took apart one of those OEM lift pumps and modeled it using a CAD program for one of my classes last semester. I would be willing to bet a lift pump that the internals can take 50psi or greater.

I would suspect you would need a stronger spring in the lift pump, thereby making more pressure. And more force on the IP camshaft, which is the big question. I'm not willing to bet an IP
