I have a 2015 and today the tank sprung a leak. I thought it was a loose hose, but to my surprise the tank had a pin hole were it impacted the frame? Both side under the tank were creased? See the picture. Anyone seen this? I'm puzzled how the frame member could touch the tank? Bike has never been down, and the tank has always been on the bike.

Is certainly odd, no explanation from me but it took something to make it happen
If not warranty and I think they will say no
I've fixed leaky tanks with both araldite and quick metal, think any two part epoxy would work
One of these was my Africa tank, made night before crating bike to Mombassa in Kenya, filled there it pissed out, araldite got me to UK and is still holding 32 years later ! Araldite is forever. Clean paint etc off first
Just make sure it can't rub again, spacers under mounts maybe ?
I'll check ours to make sure it clears too, thanks

Your right some of this new two part puddly works great. I can't imagine what happens to cause the impact? After I have it welded or brazed, I'm warping the frame with rubber. Hate to be fire ball!

I don't advise warping the frame, but rubber prob wouldn't anyway, I think you should tell Ducati this has happened, if it is their assembly fault, they need to know sharpish, potential doesn't bear thinking about, I'm struggling with cause myself. Tanks bolted fore and aft

Walter,

I'm with Jackson, do you mind to pass this along to your dealer? I've had my tank off but never paid attention to the underside. We've heard of leaks from the hoses and connectors, but I believe this is the first for a hole in the tank.

Good point. I took it over to the guys at the local shop. They never seen anything like it, and checked the recall records. They are taking no action.

Could it be a blocked breather pipe creating enough vacuum to suck the tank In?
Do you really think the tank can have enough vacuum to implode a steel tank? I did remove the charcoal canister, and I did note a strong vacuum when I opened the tank last.

After I get it welded, I'll check the breather pipe. Imploding at a leak point is the only possible thing, I can't see how the frame could have done it.

When you removed the charcoal canister, did you (accidentally?) block off the breather hose that ran from the tank to the canister by any chance?

Yes, I plugged the one that went to the canister and left the overflow open. I think your right, I hear rummers that DUCATI tried to use plastic tanks and found they broke off there mounts due to expansion and contraction. Guess that cap plays a big part in controlling the tank pressure. Expensive lesson learned.

Thanks for the help on this!

That shoudn't happen. The only way i see it is that duca-thai installed a defective/lemon tank at the factory during assembly. Have it replaced under warranty. But first, undo what you did on the charcoal canister before you bring it to the shop. Otherwise, they might blame the mod as the cause just to avoid a warranty claim

This. Yes, it has.

Asking again just to be sure: what did you do with the vent line form the fuel tank to the carbon canister when you removed it? And with the other two hoses?

Once I weld the tank I'm going to leave both overflow and vent open.
