Hello all you good people
I wonder If you could help me - I am trying to figure out why my engine i running rich - If I try to messure vaccum on the hose connecting the flamearrestor to the fuel presssure regulator I get nothing. The messurement is done with the engine at idle ( 650 rpm) I would think that the vacuum would be highest when at idle.If I pump the hose using a vacuum pump the fuelpressure drops and the ECM sounds alarm for low fuel pressure?
Thanks
