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

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

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.

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

Good quality nothing to complain about

Worked great on oil cooler system for NV4500

Fitting came as described, great shipping.
