I am trying to install a oil pressure gauge in my g, but I don't know which oil filter sandwich adapter to get. I think someone on here said the perma cool 186 works, but I don't know for sure. Can some one let me know? Thanks

 

I believe it is M20 x 1.5mm

This is the one I will be picking up: Oil Filter Sender Adapter - 20mm 1.5 Thread

It has good reviews and at a good price.

 

That's funny I emailed them and they said that they didn't have anything available. Maybe I was not clear on what I was looking for. But anyway, yes they are good quality. I have had one on my 4 runner for years and not a single problem. Sometimes when I do a oil change I have to retighten it, but that's it! Thanks I am going to pick one up too!

 

If you want one that's barely used I've got that exact adapter that I can send you for $20 shipped, shoot me a PM if interested.
