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.

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

Great parts!!

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.

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

Good quality nothing to complain about

Very good product, expensive but worked very well

Fit good no leaks

Fast shipping. Great looking fitting. Very good quality. Thank you! Work great for my oil pan for my turbo return feed.

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
