I ordered an adapter (10.0x1) from ACS.
This is the size I got off this list as to what is needed for the oil
pressure gauge post. Well... it doesn't fit, the threads are finer on
the oil pressure gauge sender unit. Sooo.. what is the real thread
size for the Oil pressure gauge port on the 13B? What is a good source
for an adapter to go from the oil pressure port to pipe thread?

I make my own
by cutting off the shank of the stock pressure switch and then drilling and
tapping it to 1/8 inch.

Excellent idea, why didn't I think of that? Will
be using a new sending unit anyway. Looks like the ID should be enlarged
for re-drive oil.
