July 23, 200817 yr Symptoms: 1985 Brat - Oil pressure dash guage reads near 75 psi all the time, hot, cold, idling, normal driving, even when the engine is shut off. Measures taken so far yielding no changes: completely rebuilt the oil pump (new o-rings, shimmed the spring, new mounting gasket, etc.) Installed new sending unit. Most likely culprit is....................._______________? If its the wire lead wear are they prone to have problems?
July 23, 200817 yr Author Disconnect the wire and see if it goes to zero.nipper Disconnected it from the s/u. Guage stayed in same place, just below 75 psi. Sending unit is brand new NAPA. Next place to look?

July 23, 200817 yr ...Or the Gauge`s Wires, it could be a Wire Grounding... Except if the Gauge doesn`t Low even with Battery Disconnected... in that Case, Just the Gauge itself. Good Luck!
July 24, 200817 yr Since you state that the gauge shows a reading even with the engine of then the gauge itself is stuck and it needs to be replaced.
