hi guys,

I was just wondering if anyone knows what the thread diameter is in an RB block where they have blank plugs?? went to put oil pressure sender in but diameter on sender is to big so prob have to get an adapter now would be easier to buy if I knew correct thread..

cheers guys

Ther are a number of threads that they use either 1/8th gas or 1/4 NPT.

hey coparts41,

cheers for the reply my sender unit I have got is 1/8 so will prob get a 1/4 - 1/8 adapter and hopefully that fixes the problem..

cheers
