esxefi Posted February 10, 2009 Share Posted February 10, 2009 don't know exact figure but between 150-190psi should be ok depending on what fuel you use. Link to comment Share on other sites More sharing options...
sparky_spit Posted February 10, 2009 Share Posted February 10, 2009 And check to see that they are all about the same, within about 10% or so. Having 4 at 140psi is better than 3 at 190psi and 1 at 140psi. Link to comment Share on other sites More sharing options...
