No oil pressure on stock gauge

[fordcummins]

Ok I just had a motor swap in my 2001 dodge auto, had a 12v put in it and have no oil pressure on gauge scared me for a min but took off hose to turbo just to see if I had flow and it is shooting out could this just be a bad sending unit

that or gauge. but try with the sending unit first since those are generally cheaper.

sounds like you solved your own problem. T in a seperate guage and try that or just replace the sensor i dont think they are very much.
