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

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

Fit good no leaks

This worked fine for me, I used it for my oil feed line rather than gas. The threads got messed up so I couldnt screw the nut on unfortunately.

Works well, the teflon washers are water tight.

Works great

Fitting came as described, great shipping.

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

worked perfect for me

Good quality nothing to complain about

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