I have brand new straight corded A20 BT for $975 if you are interested.

OK. The full pegged situation ended up being a broken wire. With that fixed, it does seem to respond more normally when turning the master off (below 0psi) and when pump is on (about 20 psi). The issue now is that when the master is off and the pump is off and the mixture in full rich and the engine is NOT running, the gauge still indicates about 4psi. Is there an adjustment to zero the gauge when it is at a known zero pressure?

24-0557. Thanks for the reply. It is pegged full right sitting quietly in the hangar.

I have a M20J with a fuel pressure gauge pegged on wide open. Master on or off doesn't matter. Initially, it would peg pretty quickly when the electric pump was on and always when in flight. I replaced the pressure switch under the cowl for about $100 and that didn't do anything so I am thinking its the gauge especially when it is full time pegged. The JPI shows that everything is normal as far as flows. The gauge is part of the multi-gauge cluster and each individual gauge has the two small black screws on the lower part. Does anyone know if anyone overhauls these?
