Everything worked fine except the oil pressure sending unit it gives readings all over the place wont show the real numbers . And the oil pressure gauge start read a very high 87-91psi. When the motor is off still in 88psi. I would like to get a new sending unit to see if it works properly

Installed it pretty quick, and the gauge itself seems well made. But after comparing to a mechanical -oil pressure and coolant temperature gauge, they are both off . After bringing the truck up to operating temperature The coolant temp on this gauge read a max of 140*f . when the mechanical gauge read 191-195*f . Which I confirmed with an infrared thermometer. And the oil pressure gauge at cold start read a very high 87-91psi (actual psi 60-66)and at operating temperature idle read 36-43psi. (Actual psi 21-24). Voltage was spot on though….

This amends my earlier comments. I installed in my boat on a small diesel engine. It was carefully wired with a solid ground at the engine. Oil pressure did not read correctly and after a lot of work I found the most simple explanation. "G" on the sending unit is NOT to be the Ground, rather it is the signal terminal. The "manual" - only a wiring diagram - shows two terminals and a chassis ground. There is no identification of which terminal to use. (G or W). I assumed G to be ground. Had it made this clear I would never of had any problem. With a better detailed instruction to eliminate possible hookup error I would have given it 5 stars.
