John and his company was kind enough to donate two DEF caps for the forum for me to do some giveaways for our members.

I haven't exactly figured out the best route yet, but something along the lines of "most referrals" or "top poster" are some suggestions so far.

Here are some pictures.. I can say they are top notch quality and look very nice at that.

Awesome. my factory def cap is junk. But to be fair ive used it more than anyone else in the world :) post a link where we can buy please.
And I did have to stop using the green aluminum cap when I started using bio fuel. The o-ring started swelling and I couldn't push it in or remove it, but I like the idea of the aluminum cap for the def, then I could remove it and clean it.

@moparecodiesel , most of the fuel caps use a regular buna rubber o-ring, you need to get a Viton o-ring and then you should be good to use the fuel cap again. I can find out what size if you'd like. Just let me know which cap you have

We sell the DEF caps on ebay but I will give you a better price if you do it direct.
