Thanks Jerry, I'll check that the next time out. I appreciate the good info .

I recently purchased a 65 m20c and have enjoyed getting to know her. I have developed an issue with high fuel pressure. At my last start I noticed the fuel pressure showing above redline at about 8psi . (It was not that high when I test flew and brought the plane home) Before start, I ran the boost pump and pressure came up to about 5psi which I thought was about right. Since the pressure is showing correct with the boost pump I'm thinking the guage is okay. So, is there an adjustment on the carb for pressure? Other possible areas to look at? I bought the plane from an airport at about 1k ft. I now have it at 6500ft but I can't think that would cause a difference. And if so, should show on the boost pump also. I would appreciate any insight or experience you can offer. Thanx! Paul

I have an opposite problem. 65 m20c. My fuel pressure suddenly started showing above redline. I moved the plane from 1k to 6500 but I can't see why that would matter. Any idea what the cause might be? When the engine is off, the electric pump will show pressure at about 5psi which seems about right. Thanks!
