If you've fought those POS flip lever gas caps on your fuel cell before, and who hasn't, then you'll appreciate this new all billet screw on fuel cap. Chris bought me this for Christmas and she even installed it for me the other day. Note: Little hands are a plus for that project... Pro-Werks are making these now in both 6 bolt and 12 bolt versions (12 bolt shown) and they are very nicely made, we got this one at the Chassis Shop. This should make filling up old blue a bit easier without having to fight that old flip lever ever again. One thing I did learn is that you need to lube the o-ring with some silicone grease. I first lubed it with some lightweight oil, but after it set a while it was almost impossible to unscrew. I didn't really think much about it but according to Stu at Pro-Werks, the o-ring will absorb that light weight oil so he recommended using a silicone based lube. I used some Permatex Dielectric Grease on it (which has silicone in it) and that seems to have done the trick, it's pretty easy to unscrew now. Oh, by the way, if you need a 12 bolt flip lever type cap for whatever reason, I have one for sale cheap!
