correct fuel pressure?
 
installed a fuel pressure gauge and tapped into my primloc fuel filter relocator in the plug that brings the fuel to the filter, at idle im at 20-21ish, and wot around 32ish and i just put a brand new lift pump on the truck. is there where i should be at for the mods done to my truck or im i still battling a air leak and the pressure is low?

Based on those numbers it looks good, except, the numbers probably aren't accurate. You need to measure the fuel pressure where it enters the pump.
