Hey guys, did you have to use some kind of adaptor to get the oil pressure sending unit to thread into the hole on the block? If so, what size is it?

Most of the blocks I've seen have a 3/8" NPT connection. The stock sender should match that, although Advance has tried to sell me a sender with 1/8" NPT. My Autometer sender was 1/8" NPT, so I did use a 1/8" NPT female to 3/8" NPT male adapter. Check the plumbing section of a hardware store.
