GT Gas Tank - ALERT

Hi All,

This weekend, I took my GT in for the flange recall and my 4th gas gauge strip, and was bracing for the 'oh, we found something else...' discussion and sure enough......

History: Back in '13, when my first gas gauge strip failed, I occasionally smelled gas and had also smelled something burning/hot. I took her in for the repair -- they found a pin hole in the gas tank and replaced the whole tank - covered under extended warranty.

Current: This weekend - they showed me the failure below and reported that my gas tank had to be replaced again!

Photo: As you can see, there is a plastic ring that is covered by the aluminum collar (revmoved) -- the plastic ring is broken at ~11 o'clock. My only warning of this failure was the tank strip - I hadn't smelled gas, or previous hot/burning symptoms.

Summary: The dealership says the tank has to be replaced - the white plastic ring is reportedly integral to the tank. This work is covered under warranty of the previous replacement ; however, I'm wondering about the repair approach I would take if it wasn't!

Clearly the Gas Strip is a weak link in BMW bikes - but the tank too?????

I still love this bike - 52,000 miles and an amazing machine - so far, ALL my repairs have been primarily fuel related -- weak link???

-Stephen

Well, my second replacement fuel strip just failed two days ago. Let's see if they find an issue w/ the tank. 46k miles.

Re: GT Gas Tank - ALERT

FYI - I have since learned (through a repair on my '09 GSA), that the problems I experienced on my '07 GT were related to an emissions canister failure. In addition to the details I provided originally on this failure - I also noticed a vacuum problem that required the use of a lot of effort opening the gas cap during fill-ups.

A number of GS owners have removed their emissions canister (they have actually identified a process called - canisterectomy) - while others replace it; nonetheless, the vacuum created by a failed emissions canister CAN cause gas tank failures.

I might have been more aware of this failure had I had to repair/pay for this failure with my own funds - extended warranty covered these failures.....

I have not seen anyone in this forum reference this - or experience the failure; however, in observation of the canister/fuel system and discussing this with knowledgeable resources in other forums - I'm certain that the emissions canister caused my GT gas tank failure and the other fuel system problems I reported previously.

I wanted to circle back and provide this update in case you experience the same difficulty in opening your gas cap and rough operation following a fresh fill-up at the pump...

The condition above is most likely the result of a stopped up canister vent line. I am assuming that the bike, being a GSA, sees some off road service. Fine dirt and fuel vapors cause the vent line to get plugged.

I had the same problem with a KRS that was operated on a long soft dirt driveway in order to get from/to the house to reach the highway.

Worth looking into for GS owners who see dirt.

Agreed, however, I experienced this phenomenon on my GT long before I had the GSA - my point being that a plugged canister on the GT caused the following:

- intermittent performance after fill-ups - multiple restarts until ~75 miles after fill-up
- gas fumes and occasionally a whiff of something hot/burning - canister most likely
- vacuum condition on fill-up that made it difficult to get the gas cap open

Not sure if anyone has performed the 'canisterectomy' on the GT; however, many GS riders have removed them and regard them as a nuisance.....

Ive done the canisterectomy on the GT but that is a different issue than the white ring crack the op has. His is the first I have ever seen or heard of breaking.
