smallblocksn95 Posted April 23, 2013 Report Share Posted April 23, 2013 What should fuel pressure be set at while running? I currently have mine set at 39psi, timing at 14*, and run 91-93 octane. Link to comment Share on other sites More sharing options...
Venom351R Posted April 23, 2013 Report Share Posted April 23, 2013 It should be set to 39 w/ the vac line off. Sounds like your pretty close to where you should be. Mine reads around 40 while running. Link to comment Share on other sites More sharing options...
