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:bomb:! 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.:sos:
