I have a 2009 f150. About 2 years ago the gas cap started to play. I used duct tape to close it for 2 years. This article somehow ended up in my Revain feed and I said heck, I'll give it a try. There are no instructions, but it was pretty easy. This solved my problem for less than $20 and it makes me happy. Is it ideal, no. But that's 90% product.
