cummins oil pressure?
Hey all,
I did a ford cummins swap on my 1990 F250. Installed a 98 24 valve. I adapted and installed my ford oil pressure sending unit on the cummins engine. I put the sending unit on top of the oil filter housing where the 1/8" pipe plug was near the oil output for the turbo. My problem is when the truck is first started it pressurizes and reads normal on the dash, as I run the truck down the road the oil pressure drops in correlation to the RPM, to a point where the trucks running at around 2200 rpm and the guage is in the RED! Is the cummins normal to run lower oil pressures at higher RPMs? Can someone tell me what the oil pressures are supposed to be so I can hook an analog gauge to it and watch whats going on? Maybe its just a ford guage issue and not the cummins, cause it runs fine.
