I have an 87 Ranger and the oil pressure gauge is slow to respond changes in pressure. Is this the way the gauge is designed to work or do I have a bad sending unit?
Locate your oil pressure sending unit, depending on which engine you have. Is the sender a silver bulb looking thing about 1 1/2" diameter, or is it a smaller sender about 3/4" diameter?
Its a real gauge, has the bell shaped sending unit. It does fluctuate with rpm just responds very slowly. Never had a oil pressure gauge operate this way. I don't know if it is normal to operate this way or if I have a bad gauge/sending unit. Added a aftermarket gauge and oil pressure is fine. If I have a problem I would like to fix it and get rid of the aftermarket gauge, if not I'll leave it in.
a bit off topic but the connections for the temp indicator on my '94 were green/crudded. a cleaning repaired and now gives proper temp
was reading about 1/4 way up the dial when engine was stone cold
