I'm really wanting to add an oil pressure gauge soon and have some questions for those of you who've done this. I'm going to pick up a sandwhich adapter and gauge from gloshift, which also come with the wiring. I take it the adapter uses a rubber gasket just like an oil filter. It seems this would have to be replaced from time to time right?? If so, are the gaskets available? Maybe that shouldn't be a concern at all?? Second, I plan to tap switched power from the fusebox but don't want to tap into the headlight circuit for the dimming feature (optional according to the gloshift wiring diagram). For those with a gloshift gauge...will it be too bright at night??

 

I used the GloShift sandwich adapter in my 2007. It had some type of seal but I honestly didn't pay close attention to what material it was made with. When I remove the oil filter, I'm careful to not turn the adapter, both to maintain its seal and to not have a problem tangling up the gauge wire.

I did not use a GloShift gauge. VDO makes a gauge that is almost a perfect match for the stock Jeep gauges. Actually, they make two similar ones--one with a black bezel (X/Sport compatible) and one with a chrome bezel (closer to the Rubi's silver painted gauges). The gauge font and needle color are pretty darned close to OEM. My gauge is mounted in the sPOD controller above the rear view mirror. At first I had it directly wired to the power switch on the sPOD controller (bear in mind there are four different styles of Jeep JK sPOD controller--with and without a gauge hole and with and without a power switch). That meant full brightness. I didn't' find the gauge too bright. However, I eventually modified the sPOD controller wiring so that it would act as an "off-road configuration switch" for all of the other circuits. Since I wanted the oil pressure gauge lit all of the time, that meant rewiring it. So now it runs to the dash light dimmer circuit. Normally I have the dashlights set one to two stops below full brightness. The gauge is not too bright, even though now it's the only thing up there that's lit up for street driving. Here is a picture of it before I rewired the controller (IOW, full brightness) ...



And here it is in the daytime ...

 

Thanks for the insight, and I'll check out the VDO gauges.

 

It uses what I think is a neoprene ring. Flat side goes against the adapter. (Probably doesn't really matter, though.)
No need to change it unless it starts to leak. If you take it off after years of use, you may want to send for a new one.

 

Thanks again for the replies. Just did some more checking on the gloshift website and they do sell gaskets for 2.99. Found them under "replacement parts". I think I'll pick up an extra just in case I have to replace it down the road.

 

This is the one I bought, along with their sender unit. Sometimes the pressure reads very close to the high end of the gauge--you might want to go for a 100 PSI model. Mine has never gone higher than 70, though.

Thanks for all the help!
