Fuel Cap Repair help

[latvius]

Anyone got ideas on how to reattach the chain? Or pictures of how it used to attach would help me fab something.

I thought of pop rivet also blind nut but never tried to put one in plastic. I don't want to break it since it seems like it would be hard to find a replacement.

Hope it helps, I googled for a part number and no go, I did find marine chain and fasteners for an aftermarket marine cap, maybe they're the same size. The TM should have the part number and/or specific fastener size.

You're right to be worried about breaking your cap. You can occasionally find a used one on eBay for entirely too much money. It's cheaper to replace the entire fill hose with a civvy part.

Here is a better picture, yeah the TM that is not indexed, I found the PN, part is over 40YO so...
Hillbilly has em for $100 so that tells me you can't get them.

That's not a bad idea using those plastic inserts

Maybe put a flat washer under the head to encourage it not to snap off the umpteenth time it goes for a swing at a gas station.

Guess who's going to dig around in the garage and sell a few gas caps?

Also looks like a possible 3d print project.

Y'all are seriously overthinking this. I'd have cracked my cap in half putting a blind rivet in it and replaced the whole assembly with a civilian unit by now.

One of those body plugs from post #3 on this thread would be your best bet, the absolute fattest one you can squeeze in, believe me those plastic fins won't let go....

Just cut it short so when it breaks off, you can push it in and install another one. You can snip them to a point with a good pair of shears or wire cutters.

I don't want a civy filler neck, but that answers my question about the blind nut

I don't know that it would break. I just anticipate the worst outcome and have layers of backup plans.

Oh I misread, but I think I will take some measurements for future reference.
