So when adjusting my fuel pressure at idle, 4 bar with the vacuum line hooked up is too much?Potentially. Pull the vacuum hose of and stick your thumb over the hose and this is when u should have 4 bar.And hunt as in surge back and forth Edited 14/07/14 10:48 PM by gaz097 Link to comment Share on other sites More sharing options...

There's no provision for test Fuel Pressure as it's rarely an issue. Do you happen to have the torque app and a odb dongle?First point of call for fuel issues it would be easier to check the fuel trims before installing a gauge.
