Add me to the cracked fuel tank list

I didn't even notice it until I took my 8gs in for new tires. Yes, I live in the brutal desert 10% humidity if your lucky it's only 100 today heat. Tank is on order. Sad part is that a fellow service customer was in for the 2nd time on his 1200GSA and it's failure to start. Towed in twice. They replaced the fuel pump once and were going to replace it again. He has 700 miles on the bike. Ouch!

Ouch.... I`m 300 miles east of you, and have not cracked mine....yet. As you noted with the fellow 12gsa..... You might wan`t to use chevron techron with every 3 fill up..... That seems to fix the corroding fuel pumps, as they are damaged by the ethanol in today`s gas....

I think the cracked fuel tank cover is inevitable for all bikes. It is a design flaw with the plastics so everyone go check yours if it hasn't been replaced yet! :eek1

Just found my replacement tank cracked this last weekend!

Yeah!

Time for a third tank I guess.

chevron erling, chevron. lol. not shell.

Or Texaco.

damn................ was tank #2 the new style?
Maybe they slipped some old stock in on you?

Arrrgggggg.... Too much espresso...... Thanks for catching that....

New style. You could clearly see the difference in radius.

Crap... I was really really really hoping you wouldn't say that ...
Mine (original - 2 yr old tank) is cracked... I guess I'll wait til the 35th month of warranty and hope an re-re-designed unit is available....

I have a 2009. My tank has more pronounced cracks on the left side ... you can see the start of a crack on the right (fuel fill side). Replacement tank is at dealer and will be changed out at next service.

Thoughts on whether this issue will be dealt with outside of warranty? Not thrilled at all about paying for this out of pocket (repeatedly) when warranty is up. :eek1

I would think that BMW would be obligated to fix such an issue (outside of warranty). If not, class action would seem like a given for such an obvious defect?

My yellow 2009 had a severely cracked tank a while ago. Got it replaced under warranty, and it hasn't cracked since. It's been at least 8 months to year now with the new tank. The new one they put on seems beefier in the crevices/creases where the old one was cracking.

WTH? This is the first I've heard of this...

Yep, cracked, and being replaced under warranty.

cracks?!? shit... i gotta hole....

Holy shit!! Did you puncture it or did it just start spewing on it's own?! It'd be hard to believe it'd just do that on it's own. You had to have punctured it somehow! Tell us how!

touratech tank install!! damnit Griz I was hoping to fool a unsuspecting noob!

Ahh, I see! Sorry!

Just a reminder:

From the votes so far it does appear to be a USA-canister-system related problem....

I smell something fishy...

First of all, while the data is interesting regarding the canister it is far from conclusive. Several pieces of evidence points to other causes, mainly:

1. As a mechanical engineer who has designed his fair share of injection molded and thermo-formed plastic parts the radius on the original tank is too small to withstand repeated loading, such as cycling pressure or fuel load. (which may point to the canister as a factor in the problem but not the root cause.)

2. BMW issued a change to the design by increasing the radius on the outer gas tank cover.

3. I haven't looked very hard but I haven't seen a confirmed crack on the new design tank, mostly rumors, second cracks are likely on the same part
as original.

4. Many F8s have been reported cracked with less than 10 miles on them at the dealership (I've seen one myself). This points to a fabrication/design flaw with little to do with repeated loading of the outer shell.




Granted, there is a problem, and everyone (especially you JR) shouldn't be a chicken and take their bike into the dealer and demand a replacement under warranty. You say in your other thread you don't want to take it in because it is a hassle?... WTF, that is like saying you don't want to talk to a guy for two minutes to automatically get 500 bucks just because you don't like his face. Man up and go get a tank, if they refuse, I'll give you my number and my dealers number and they can talk them into it.
