Anybody know what size and pitch the threads are on the OEM oil pressure sending unit? I am trying to find a fitting but can't seem to find the details on the thread. Thanks!

 

It's some metric version of 1/8NPT....someone else probably knows what

!/8NPT will fit if you taper it down more with the die...

 

Thanks! Yes, its not 1/8 NPT. I have tried that. I thought about using a die but if you know where to look you can get just about any fitting. I want to try to get the right fitting before going that route.

 

It's probably M12X1.5T......

Well...it's not:-) Might be 1/8BSPT??

You can buy autometer adapters from 1/8NPT to 1/8BSPT......Saw them today at an autoparts place....didn't try the adapter to see if it fits though

 

I'm thinking its closer to M10x1.5. I am going to try picking up a couple of bolts this week from the hardware store to see if I cant get any closer to the actual thread. If that doesn't work I will use a die on one of the 1/8 NPT fittings I already have.

 

M10X1.5 isn't a tapered pipe thread....
