John Scott Posted May 19, 2013 Share Posted May 19, 2013 (edited) After running my Mallory 140 through two Hybrids, Procharged 4.3, mid late 90s to my 383 V8, its finally starting to show signs of wear. It came with a boost regulated return style regulator, took out the regulating spring in the pump on day one for the Procharger and could hit well over 21 psi at 14 psi boost. I left it this way for my 383 v8 of nearly 12 years, 7 psi max for N/A carb. 1/2 inch lines in and out. Using a return line is the only way to go, keeps gas fresh, pump cool and stress free most of the time. 17 years of abuse. Rebuild kit under 60 dollars and can be converted to alcohol. Not many other electrics can go this long. Just making a plug for a great product. Edited May 19, 2013 by John Scott Quote Link to comment Share on other sites More sharing options...
