I bought a mopar oil pressure sending unit to fix the oil pressure gauge and when it's cold it works fine its right in the middle then when it gets warm it hits zero and when I hit about 3000 rpm's it goes up 1/4 on the meter and the jeep runs fine when it's at 500 rpm's any suggestions of what it could be

Well that part I don't know yet cause when I'm at low rpms I have no trouble at all but I was wondering that to how can I find out if it is
