the switches are profuse.
10mm clean cut ISO metric,
10mm tapered
NPT
British pipe thread.
the size goes back to long long a ago most car co. in japan copied the very old 1960s MG's engines. from Britain.
including this switch .
and then made zillions of them and year by year, just had do use them.....
on one car bought a BSPT to npt adaptor
then use NPT TEE and to that, a npt Idiot light switch at 3 or 10 psi.
then from there NPT to gauge, our gauges here are all NPT
but cant guess what you guys uses.
id adapt yours to BSPT. and
it sure is a pain
and for sure you dont want to cross thread the aluminum block fine, BSPT threads. (easy if the thread pitch is wrong)
