Oil pressure sender problem

Monty2556 - 28/4/14 at 09:18 PM

I've got a 1600 x flow engine with a 691 block. The oil pressure sender hole has got a dodgy thread. Does anyone know what type of thread it is? It's about 3/8 inch diameter. The next question is - where do I get an adaptor to take both the oil pressure sender and oil pressure gauge take off? I assume because of the age (circa1970) it's an imperial thread.

If my memory is right it's a 3/8 NPT to 1/8npt

eBay jobby. I'm sure my 711 block needed the adaptor but the 691 didn't.

If you give EUROPA a call, they can proberly sell you the correct part.
There is another similar company but the name will not come to mind.
