Upper Radiator Hose 36mm?

[Merkles]

I have an autometer water temp gauge and I am going to buy a Greddy upper radiator hose insert so I can put the sensor in it. My question is does anyone know if I need the 34mm insert or the 36mm insert? Thanks

I'm not sure of the exact size, but you may want to contact RRE since they sell them and would know the right answer. Here's their listing on it (towards the bottom of the page):

Let us know what they say so that future searches on this thread will help others if they have the same question.

P.S. You could also save a few bucks and just re-tap the existing coolant sensor inlet on the water neck with a 1/8" NPT tap and not have to buy a hose insert at all.
