Ls swap 87 d100 fuel pump question
Doing ls swap in 87 dodge d100. Only fuel pump I could get to fit my tank is out of 05 Silverado. The 05 Silverado has a fuel pump with fuel pressure regulator built in internally. There is no return line . My LS had a regulator on the rail but switched it to returnless rail. Will the internal regulator work and maintain pressure?
