Water temp gauge adapter size?

I’m installing a Blox water temp adapter inline with the upper radiator hose to run the water temp gauge and was wondering what size shoud I get.

The upper radiator hose size for a 91 DA is 30mm… so do I get a 30mm adapter or a 32mm?

I’m thinking 30mm since it’s the exact same size but it might be hard as hell to get on or should I go with a 32mm and use a clamp to clamp it tight?

smaller would be safer in that instance. better to be tight instead of loose and rely on a clamp to hold the hose on.

Cool… thanks!

I have the blox 34mm, and it fits fine with no leaks.

A 32 shouldn’t be hard to get on, I’d rather have it a little bigger.

Yeah I wouldn’t think a 32mm would be hard… I was just undecided if I should go with a 30mm that’s all… but seem like either would do the job. Thanks

Another question… how did you mount it? Did you face the hole downward or sideways? Or does it matter? Have any pics of the install? Thanks
