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.

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

Works well, the teflon washers are water tight.

Fit good no leaks

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 great on oil cooler system for NV4500

Very good product, expensive but worked very well

Works great

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.

worked perfect for me
