asmoto05 2 Report post Posted June 5, 2011 A buddy has a 92 sho, changed fuel pump, fuel pressure regulator, fuel filter. Turn key gets 20 psi about then key off and it drops off. Any suggestions for him? Share this post Link to post Share on other sites
BuckeyeSVT 79 Report post Posted June 5, 2011 Clamp off return line to check for bleedout through the regulator ( I read it's changed but I would still check ). Also , is it a store bought fuel pump?.. Some of the cheap replacements have cheap check valves which can allow fuel to bleed off through the pump internally. Aside from a leaking injector... Or line/ fitting leak... Good luck. Share this post Link to post Share on other sites
