oil pressure guage

[michael]

Is there a Volkswagon part that matches an oil pressure sender for a 1992 RT100?

Be aware some switches leak through the plastic body of the switch. There are ways to seal the switch. MaxBMW's site has some good info on the OEM switch.

The ACVW OP senders are usually 1/8 NPT. My /6 takes a straight thread sender with a crush washer. I was disappointed when I couldn't use my VW stash when my sender started leaking.

I am assuming that you are looking for the single terminal switch that actuates the oil pressure light, and not a 2 terminal sender unit that would actuate an actual oil pressure gauge and light.

I'm pretty sure some old VW oil switches have the same thread as your bike, but be sure that the function is the same.
Some VW oil switches are grounded when there is no oil pressure which is what your airhead needs.
Others are grounded when there is pressure and won't work on our bikes.

If I was looking for an alternative oil pressure switch I would consider a higher pressure setting. The stock switch is set at 5 to 7.5 psi and I would prefer to know of a problem before the oil pressure got quite that low. 10 to 12 psi would be better if such a thing was available.
