Does this require the use of a specific oil pressure sending unit? In the past, I have used the oil pressure sending unit that came with the gauge; however it started leaking on top where the wire connects. I tried tightening down the bolt on top; but it still leaked. So I replaced the sending unit with a stock application from the local parts store... now my gauge is off the charts and pegged at over 100 lbs.
Any ideas?
