Border4x4 Posted March 19, 2011 Share Posted March 19, 2011 Hi, I have a ford F-250 7.3L in the workshop at the moment and just doing some tests and I think there is not enough fuel supply from the low pressure pump to the high pressure pump, I have put a gauge on there to check the pressure and it reads 50psi is this the correct reading? Thanks Quote Link to comment Share on other sites More sharing options...
mintalkin Posted March 19, 2011 Share Posted March 19, 2011 Factory pressures are anywhere from 40 to 70psi so 50psi should be ok. Quote Link to comment Share on other sites More sharing options...
