??What size hose??
 

I`m attempting to install a water temp gauge and was wondering what size is our upper radiator hose?

I did some searching and found 31mm but I wanted to make sure.

I order a 32mm water temp. sender:

Water Temperature Sender Radiator Hose Adaptor

They only have 30mm and 32mm adapters so I went with the 32mm cause I figure the hose can stretch a little and I`d rather it be tight than loose.

Any thoughts or opinions....

Thanks!
