Fuel bag repair

I own a few Avon fuel bags. Those black ones that you hang from your tubes.

One of them has developed an unfortunae leak at the top.

Is it possible to repair those? AFAIK they are made of hypalon.

Hello. I looked at repairing mine. They can't really be repaired. And for what it's worth you may as well get new ones save them leaking. Just the reinsurance and one less thing to worry about.
Seaflex make them.

I'd think that was good advice

Don't bin it just yet...they're repairable with polychloroprene glue (hypalon glue).

If it is a small hole or puncture, just patch it as you usually would.

Aren't the bags stuck together in the first place? So why would a patch not work? Only asking SIT inflateables do them to £280+vat 20 Lt

They aren't 100% fuelproof as far as I can see-if you put premix in them for example, they go oily on the outside after a while.

I'd be interested to know if anyone has managed to get glue to stick to one.

Elastomers are very slightly porous...moreso in this case, because the inside should be CSM. So rather than an inflatable that is neoprene inside, polyester fabric, then CSM on the outside, the fuel bladder should be CSM/Poly/CSM.

I can see this being a classic example with the problems of the new petrol with E10 (10%) Ethanol making it more problematic with older fuel delivery systems, hoses and fuel tanks and I guess now hypalon glued petrol tanks.

Ethanol is an excellent solvent, drying agent and cleanser which could also be a big issue with any glue that the petrol comes in contact with.

I wonder if it's more prone to break down any glues that it's in contact with?

I see no reason why you shouldn't give it a go, what do you have to lose?

Hopefully it won't be a issue.

Heya guys, thanks for all the tips. Did a bit of poking around yesterday evening, and after a bit of pulling, the entire thing ended up falling apart at its seams, which is really unfortunate, but then again these things are quite old.

I might take one apart and try to glue myself a new one, or look around for some good used ones

Thanks for the advice

We're on E5 over here still. Not sure about Germany though.

Either way...the fairly high chance of a repair failing and of leaking highly inflammable GO GO juice from a Bladder while On a moving bumping pitching and rolling RIB is to avoided by all means the way I see it...and simply not worth the risk...and is easily avoided by replacement.
But Hey some people like to jump off Mountains..

If your lucky & can get access down the filler tube with some long pliers try using a small brass stainless nut & bolt with 2 fibre washers .
