I have 2 questions in regards to my Gaffrig gauges. My boat is a 97 27' Fountain Fever. I believe the gauges are original.

First Question: My fuel gauge is stuck on the full reading. Does this sound like a gauge issue or is there a sending unit that I can replace? (I had to do this once in my Mastercraft)

Second Question: My oil pressure gauge is always pegged and the red lite is always on. I dont get any alarms and my oil temp is ok so I just think the gauge has gone bad??

Any thoughts would be appreciated.

Is the fuel guage staying full or completely pegged??? If its pegged, then its probably a loose ground wire on the sender.
The tank sender is probably under an inspection cover under the back seat.It can also be adjusted with the tiny phillips head screws.
I had the same issue with one of my Gaffrig/Livorsi red line oil psi gauges. The gauge was bad..

Once in a while, used and NOS gauges pop up on ebay.

I think you're right about the ground wire. I replaced the gauge last night and it is still pegged. This weekend I will go looking for that ground wire. You think it is under the seat on a 27 Fountain? It would be awesome if it was.

We have two sets of Gaffrig Red Light gauges in black we are not using.

More than likely there is an inspection plate under the back seat.
