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

Good quality nothing to complain about

Works great

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

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

These work well for my valve covers to set up a breather systems

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