I had to install a FASS system on my p-pump conversion. I installed a PDR 12valve grind cam in it and now I have a lobe to drive a mechanical lift pump. Are the standard lift pumps reliable and do they supply a steady pressure for the p7100 on a motor with 450 hp. Are there good pumps and not so good or is the stock Cummins one fine.
