AC PERFORMANCE 12AN AN12 Straight Black Aluminum Fuel Cell Bulkhead Adapter Fitting -12 AN Locking Nut With Oil-resistant Washer

I like the product it was of good quality. I used it on a Engine bill.

Works like a bulk head should only one side has threads so its good for a fuel return in a tank hopefully the washers hold up to e85

Good product for any type of custom fuel applications. Like an ls swap, Good quality and works great no leaks.

Works well, the teflon washers are water tight.

It works perfect. Used as a breather fitting for valve cover.

Good quality nothing to complain about
