Keyless gas cap????

[GreggyG]

Does anyone have a link to a replacement gas cap that doesn't require the key? Thank you.

If you use the search function, you can find there are some ways to get that result. One used for those who have a Corbin seat, is to add a short piece of rubber gas tubing, and then a female screw-on fitting, and a male threaded cap.

I never found such a thread either in all my years here. And I never found a cap that was reported to work. Bothered me enough to make my own.

Can you share what you did?

I have a Corbin seat and leave an extra key in the cap. Maybe not the safest in the world but I live in the sticks. Who would think look in a flap in a seat to find a key???? Maybe more people now.

Probably a safer thing to do would be to get a cap from a bike with different ley.

Here is a post from a while ago that I posted about just this subject

You have to change the tank neck to accept a twist-cap. Some solutions below.

Some people with Corbin seats use an extension to put the gas cap closer to the top of the hole in the seat, and then use a screw on male & female gas cap and tube. The tube attaches by fabric reinforced rubber gas line rated tubing to the OEM gas tank neck w/hose clamps.

Here's something you would need to attach a piece of tubing to. They have aluminum, stainless steel, and steel bungs (the female threaded part).

You could also hit your local parts yard and remove a neck and screw-on cap, just find something the same size as the VMax neck which is just-over 2" o.d. Take the rubber tube too, as that material is expensive if you want to buy a length. I think I paid $20 for a foot at NAPA, years ago.

I just tried that eBay link and it is stale but if you go on a search there for the type of fitting I described you should be able to find a current offering from multiple vendors

The gas cap always reminded me of a radiator cap. I wonder if there is suitable (car?) radiator cap out there somewhere?

Some choices.


Two inch tube, removable gas cap screws-on, but allows a 'push-through' of the gas dispensing nozzle to eliminate removing the screw-on cap. A 2" o.d. tube is close to the VMax neck. $44 from Summit Racing. https://www.summitracing.com/parts/tnk-ffn



Prefer a pop-up knurled cap you remove by a screw-on/off function? Same supplier/manufacturer & sizing. $95

This one is the priced-less leader @ $40. Same dimensions 2" o.d., and the tube is 5" long. Same supplier/manufacturer.

Thank you.how do the tubes install?

Use a solid band clamp instead of a traditional serrated/slotted 'hose clamp.' They're sometimes referred to as 'fuel injection clamps.' Hose clamps with the slots in them chew-up the rubber.

Slip the rubber hose over the tank filler and the other end over the new piece of tubing opposite the new screw-on end. As mentioned, I bought a 1 ft long piece at NAPA, and used 3 or 4 inches of it, and 2 clamps. I had cut-off the stock filler neck just-below the part with the notch in it, because the cap wouldn't release. I've posted about other ways to avoid having to cut off that and how to remove a rusty or frozen gas cap.
