Anyone got a clue what the thread is on the Pinto injection water temp sender?

It's the one in the middle of the injection inlet manifold and looks to be about 15mm but I beleive it may well be NPT?

Also if anyone around suffolk has an appropriate tap I would mbe most grateful!

cheers

At a guess id say 1/4 nptf. I think there is a bsp thread that is almost the same.

nah... I have a 1/4 NPT tap and its more than twice the size.....

I was thinking maybr 5/8 ?
