[Roadsters] oil pressure guage woes

[steven boortz]

thanks everyone for the replies.

i did not buy the mcmaster adapter, but i did buy an adapter.  i bought it from Summit, where i bought the guage.  the packaging of the adapter, says it is what i ordered.  to wit, 1/8NPT female to 1/8BPST male.  i should say that, while my car is a 67.5, the engine is an H20, of unknown vintage.  is it possible the H20 block has NPT threads?

thanks again
