Hey everybody, Ive been trying to figure out how to do this on the 3.0. My first inclination was to simply use a tee fitting and have both sensors read out of the same port, however i found that due to the bsp threads a tee fitting is really difficult to come by. I was wondering if anyone else runs an aftermarket gauge and the idiot light, and if so what ports/ fittings did you use?

I currently have an oil pressure gauge on my Montero cluster (sacrilege i know) that does work, it is just a fairly slow responding gauge and i would like a backup.

 

Get a adapter to pipe thread then install your tee.

I find the threads in the block to be Metric or that is the adapters I have been using since these engines ended up in my shop.

 

Would the port right under the stock sensor work, (the one the wrench is in?) From my reading some people use this as an oil temp, would it be the same pressure?

 

Well after inspecting that plug id wager its a 3/8 bspt meaning at least id be looking for one adapter rather than 3 but still irritating. does anyone know if you can use bsp in a bspt?
