On my 2003 Silverado 3500 diesel the oil pressure guage reads zero. I've replaced he sending unit on engine and it still reads zero. I think I may need to replace the whole instrument cluster. if so, where could I purchase one?

The oil sending unit is located on the engine block behind the drivers cylinder head area.You have to climb up on the motor to see it cause it is hard to see behind the wiring harness.You may also want to purchase a new sending unit because it is very long and you might need to buy the sending unit socket to replace it.Hope this helps.Good luck.

Hi I have a 4x4 2003 chevy 3500 silverado dually with dual tanks
rear tank stoped pumping into front tank and was full . I siphoned the fuel out of rear tank and fuel gauge reads 9/16 full . is there a way to reset the fuel sending units so they can calculate the fuel readings. I always filled the two tanks with the same amount of fuel
until now ? I'm thinking there is a inkine fuel pump
have the engine oil pressure checked with a mechanical guage, if it is about 15 PSI hot replace the sending unit for the guage, u will need to buy a special deep oil pressure sending unit socket for this job, they are made by KD and Lisle tools, they can be bought at NAPA.
