I put in some Faze gauges which work fine for a while. But now the sending unit is dripping oil. It is not the fittings, I have cleaned those, and they stay clean, it is leaking around the wire connection, and around the seal where the flange is pressed to the fitting. Granted, it is not a lot, maybe 1 in puddle, but before it was a drop or two over a week, and now it is a one inch puddle.

What gauges and sending units are people using? What can I put in it's place?
