Just ordered a can of Kroil, sure hope it works. I wish they sold it in something smaller than a 10 oz can, but I'll probably find more uses for it over time. I'm keeping my fingers crossed that it'll solve the stuck cap problem!Thanks.
Oh, you will.. Kroil is great. But.. isn't Wayne right about taking the ring off? <scratching head>
I'm not certain about removing the ring. Several sources I found said that the screws easily fell into the tank, and I'm also unsure about what is on the other side of the ring. Even if I removed it, would the cap not still be stuck, due to the ethanol-swollen plastic?
take out the tank screws, now you can spray whatever you like directly on the offending parts. I don't think you can disassemble the lock until you get the cap away from the locking ring but at least you can lube the lock much easier.
Turns out that in addition to the 5 screws, the ring is also held in place by the cap itself. So, it is loosened and able to spin, but can't be removed while the cap is in place, and that's still not willing to budge.Back to waiting for the Kroil to arrive...

The 5 screws hold the ring to the tank, but the cap goes thru the ring, and its locking mechanism inside the tank is holding everything together. If the cap is locked into the tank, nothing can be removed.
The locking gizmo (technical term) on the cap shouldn't be locking on the plastic tank..
Chuck your fingers may have been faster than your memory, at least on My wife’s 03 -04 Stone the tank is metal, not plastic.
When you finally get that POS off, beat it with a sledge hammer until you can't lift it any more.Then contact member swbrenton, he made me a beautiful cap w/o the lock.Never had a bit of trouble with it.
