Looking to mount a fuel pressure regulator near the stock tank and run the return back into the tank. What regulator is everyone using that has the returnless systems used in the 99.5-01 Explorer? Also what frame mounted fuel pump are you using? I found a pressure regulator/filter combo from Holley that is set at a fixed pressure of 59.5 PSI. Is that too low? https://www.summitracing.com/parts/hly-162-590
