I got tired of putting the cap on the roof of the car, so I went out to my Big *** Van (a conversion Dodge Ram Wagon) to see how that cap was tethered. Lo and behold, it was tied by a plastic strap that attached to the body by means of a press-to-fit end. I pulled it out, unscrewed the cap, took it to the Insight, and switched caps. Perfect fit! Then I drove around with the Dodge cap on the Insight for a couple of days to make sure I wouldn't have any CELs as a result of using a "foreign" gas cap. Satisfied that the caps were compatible, I drilled the appropriate-sized hole in the hinge of the Insight lid, plugged the tether in, and swapped out the gas caps permanently. 10,000 miles and counting, no problems, and I don't lose my cap. I imagine any DaimlerChrysler cap would swap out if it has a tether... perhaps other manufacturers as well.
Personally I hold mine in my hand while filling for the sake of not getting any dust or foreign matter on the cap which might find it's way down the fuel tank and in to the engine. The first time I filled up I set it in the little flap on the door, it stayed for a few seconds before falling on the ground and rolling under the car. I wiped it down really good, hopefully it didn't get much on it.
i looked at that. I tried to find a spot in the manual that instructed me on this. Now, looking at you photo, it seems to make sense. I went out and tried this technique, and sure enough, it does work. Funny how this did not make since to me when I first looked at it. I was thinking a short tether adhered to the cap with a knot on the other end that could be placed in this tiny slot.
Whoah. Wait... I own a 2003. That picture is dark. Is there a tether or are you balancing it perfectly on some kind of lip on the bottom of the door? Or is there some extra piece included in the bin that my dealer didn't install that allows me to rest the cap on?
I was thinking of creating a very simple tether and finding a nice way to attach it. Luckily I don't go to the gas station so much that it's an inconveniance to find a place to put the gas cap. hehe. Once every 2 or 3 weeks.
I don't think that little hook is for the cap, if it is then it sure is a poor design. Honda and other manufactures have much better gas cap holders than that. I'm thinking Honda was going to attach something to that hook for a gas cap holder and then decided against it.
Anyone have any info from Honda directly.....and not a dealership.
