My 74 Warrior underwent an engine change (O-320-E3D) with RAM 160 HP STC. Since then I have been struggling with high fuel pressure readings, at times above red line. There was not a problem with this with the old engine. We have changed the engine driven fuel pump, the electric pump, changed fuel pressure gauge, overhauled fuel pressure gauge, bled the lines purging air multiple times, and the problem persists. Inline fuel pressure was tested with a calibrated gauge and reads 6PSI. We are out of ideas. Has anyone had a similar issue and able to resolve it?
