I was assembling my engine and noticed the irons I chose do not have provision for an oil pressure sender. Just curious what year irons these are.

I will just tap the rear banjo bolt to get my pressure reading I guess.

 

i believe 79 and older because 81+ are the only ones with oil psi gauge in cluster

 

80's did not; had a hole but it wasn't drilled thru.

 

Whats the thread pitch on the oil pressure sender?

 

28 BSPT iirc. It's a British pipe thread. Good luck on finding that tap in the US or Canada.

 

If it's any help I'm in the UK so if desperate just let me know what you need I'll help with the logistics of getting it to you.

 

Seriously? Can someone else confirm that.. If so I guess I'll order one from the UK.


Did a quick search and it looks correct, 1/8-28 BSPT or 1/8 PT

 

It's essentially a metric pipe thread. I do believe it's 28 but can't promise it. It's very close to a 1/8" NPT but not close enough for a good seal. Thread spacing is too different.

 

1/8" bspt.
