Mike, It's either your gauge or you have a short to ground somewhere in your sender wire. You're welcome to try my gauge in your car.

It will show normal pressure as the car starts, but soon after pegs to the right and stays there. Everything runs fine otherwise. I've swapped out the pressure sender, NAPA OP6091, and it's still pegging, so I'm suspecting the gauge. Anything else I could check? Thanks Mike Thomas Pres., Panteras Northwest Yellow '74 #6328
