Can anyone tell me the size of the openings on the greddy oil filter block?
My problem is this: The sending unit (oil pressure) that I have says it is 1/8"npt - although it sure looks larger than 1/8". Anyhow. I know I need an adapter, not sure what size. The two hex holes on the block are far too small for my sending unit and the larger hole (with the stainless BOLT) is too big. I don't want to order an adapter online, have it show up, and be the wrong size. Thanks for any help provided!

 

Can't really find any info on the thread sizes.

Why not just go to a local part store? An adapter would be a couple bucks, so why waste $5 to have it shipped?

 

not so easy to find, from what I've read.. .

 

Maybe I'm just blessed with a really good hardware store. I dunno.

Contact GReddy?

 

my best guess is this: at Lowes the sending unit fit well into a female, 1/4 tapered thread - and a male, standard 1/4" thread fits into the greddy block. So, I think I at least know what I'm looking for....
