Something isn't making sense to me right now. Do you have a link to the what you have now?
PN's or something?
Okay here are all the details. Sometime ago I trashed my transmission. Rebuilt it. Decided to put a filter on the coolant lines plus a finned cooler and 160 degree temperature control valve. Bought a Derale filter mount (
https://www.amazon.com/Derale-25753...=derale&qid=1609867884&sprefix=derale&sr=8-53).
It leaked. Tightened the s#/+ out of it. Still leaked. Took it off and discovered that the gasket surface, Though nice and shiny, was the CAST surface. Got out my files. Then 200 grit block sanding.....then 400...then 600..
Etc.
Got new Mobile 1 filter. Put it all back together. Now it leaks just a tiny bit. No matter how tight. Decided "f" this. Ordered this. ....
It came yesterday. The thread/nipple looked smaller. Checked with old filter. Yep. Went back and looked at the Amazon description. but then noticed on the frequently bought together part it showed a filter for coolant.
So I Googled the crap out of filters thread sizes Etc till my eyeballs were rolling around. And this is what I suspect is a deal. Nearly every oil filter domestic cars has a 13/16-16 thread. Very frankly I didn't even know that they made filters for coolant systems apparently maybe Marine applications use them. It seems that coolant filters have an eleven sixteenths-16 thread. The Dxmned description in the Amazon item does not say "for coolant applications".
So I start googling again and ran across those filter adapters/ sleeves.....Of course I could send this damn thing back and get the right filter Mount I just thought I would ask for an easy way out.
