IIRC it's 1/8th in BSPT, that is NOT the same as 1/8 NPT, which is what you'll normally find here in the US.

Good luck!

ahaha! it all comes rushing back to me now!

[float_6969]

What I did was to get an 1/8" NPT tap and just enlarge the opening. The thread pitch is the same, the actual diameter is different. The 1/8" BSPT is smaller. IDK why 1/8" isn't an 1/8", but the British are weird, so what are you gonna do?

i am wierd, and damnit i enjoy every minute of it! also, autometer sells the adapter.

[float_6969]

I think NISMO's got one too....

[r34 gtr]

but the autometer part is gonna be dead easy to find. hot rod shops will freaking stock that one.

So its a 1/8" BSPT, not a 1/8" NPT, if you remember correctly. And if you re-tap with a 1/8" NPT you can use the common fitting found here in the US. Nismo and Autometer make adapters.

I actually needed to know this and sure glad someone had already posted, thanks!

i think i asked about this same thing a year or two back... or someone did... anywho it doesnt matter, this crap should be stickied so one doesnt have to search for it.
