    1. I'm gonna go visit my dealer first, tell them I have filed with the NHTSA and see if they will do something for me. Can't hurt.

    2. ALSO - I have the 90-degree QD and flange cracking on *both* sides of my tank (not just the pump). Has anyone seen BMW address the right side with any changes? Is there a part (other than the whole tank) for replacing that flange?

    Yes! I just had my right side ("sucking jet pump") flange replaced due to cracks and major leakage. It's under extended warranty or I would have used the 10ovr clamp. The replacement for this side has been upgraded with a metal collar just like the left hand pump side. Unfortunately, I don't have any pics but the collar looks just like the upgrade on the other side.

    EDIT: Here's my upgraded pump side collar from page four of this thread...

    It's good that the NHTSA is looking into this issue, but they might be the wrong agency for the job. A fuel leak is more an emissions-related issue. You folks should get the EPA and CARB (California Air Resources Board) involved. They'll go bananas over a defect-related fuel leak. Especially on a vehicle with a fuel vapor recovery system (aka charcoal cannister).

    Note also that vehicle emissions equipment has a federal and state mandated warranty structure.

    Have there been any fires related to this leak?

    None that I have heard of.

    I had a QD fail on an 1100GS and it was pissing gas everywhere. Gas doesn't catch fire as easily as people think. My ST was leaking too, and it dripped right on the exhaust. Nothing but stink.

    I had one loosen up on my 1150RS. Fuel sprayed out, but it didn't catch fire. An observant cage driver alerted me, while we were stopped at a light.

    Does the female quick disconnect ever fail? Or is almost 100% of the time the male quick disconnect fails?

    The reason for asking is I think there is more potential for causing damage as it is way easy to over-tighten the female QD exacerbating any existing cracks. The female is a tapered thread IIRC and the sealant on the threads is acting as lubricant thereby making it hard to "feel" how tight.

    I am pretty certain the metal male QD will work with the plastic female. Replace the male with a metal one and carry the female as a spare.

    The female fittings do fail quite often, actually. If you are carefull and do not overtighten the female fitting installing the complete set of metal fittings is the way to go. Just tighten by hand and then maybe 1/2 a turn with a wrench - max. If there is any cracking at all on the threaded boss where the female fitting screws in I highly recommend the repair clamp (even if you don't have any leaks yet). The repair clamp is worthwhile even if there are no signs of cracking. Hope this helps.

    When I talked to the owner of my dealership I was told that it was primarily the male part of the QD that failed. They recommended swapping in the metal ones. The owner was not aware of their having seen the cracks in the flange.
    I just looked at my buddy's '07 (right angle QD only on the pump) and he has some cracks. He has an extended warranty. I'll post (or ask him to) what he is told when he goes in.

    The OEM originally started offering only the male side in metal as a replacement. However, the female side has it's weaknesses as well. I wonder if BMW had used a metal female on the bike from the start if the flange would crak as much? Seems that the movement and vibration of the hose could cause cracking of the flange potentially.

    I just got off the phone with Mediha, a Resolution Specialist at BMW (motorcycle) customer service. She said that I would need to get a "certified BMW diagnosis" (from a certified dealer, at my cost) before they could go forward with any resolution investigation.

    I"ll go back to my dealer about this, but I am wondering if this is Standard Operating Procedure (they certainly don't want to just take my word for it), or if this is a stall.

    Edit: took bike in; they will take a look, then file a "puma" (not sure of spelling). I'll pass it's ref# to the Resolution Specialist and we'll go from there.

    Thanks,

    Both flanges on my new (to me) R1200GS are cracked. I'm going with the BBY flange clamps and metal QDs.

    I'll be interested to hear (see?) how it goes. I expect that this winter I will get around to looking at mine and will not be pleased by what I see.

    Can cheap hose clamps provide the same support as the $35 clamp from BBY?

    After finally getting some time to look into where the fuel was leaking from I have the same issues with my pump flange. :becca:waysad

    Mike expect a call in the next couple of days!

    I also did go ahead an file a NHSTA complaint to add another one to their records since this does need to be taken care of.

    if you want to file here is the link

    I ordered the special clamp and installed it on my '05 last weekend. It was easy to access and seems to be the right tool for the job. Mine had not developed any cracks yet - but I store it outside in Michigan. I'm worried that if any tank will crack, it would be mine. I feel a bit better with the gadget in place.
