Oil sender
I have a 1999 46' Maxum . My oil pressure gauge in the helm fails when I'm underway. The pressure will read 40PSI at 1200 RPM but when I back off to idle it goes to zero. I put a mechanical gauge on the engine and it reads oil pressure correctly. My port engine oil sender is a one wire unit. I ordered one from Cummins P/N 43268849 and they sent me a two wire that doesn't connect
Any help on getting the correct sender would be appreciated
