oil pressure port

[LEMHEAD16]

Any one know the thread pitch and size off the top of your head?

1/8 BSPT....a 1/8" NPT fitting will start to thread in but you'll wreck the threads.

I knew it was one of those just couldn't remember which.

I just ran a 1/8NPT tap down it and it worked fine.

Shopping for parts to plumb oil pressure port for Factory dummy light and an autometer gauge.

Is it better to use brass or SS adapters and fittings? I know the Autometer fittings are brass but I'm not sure I want a brass tee hanging both sending units off it.

input?

If you unplug the dummy light it will stay off... so who cares

I think youd be best off getting one of these guys
