BMW K1200 S fuel leak problems

My motorcycle is leaking gasoline somewhere. I can't leave it in the garage due to the strong gas smell. I've removed the fairing, but still can't find where the leak is coming from.

Fuel was leaking excessively at the end of 2.5 hr ride. Repair was completed by bmw dealer 3 days later. They replaced the plastic piece that threads into bottom of fuel tank because it was cracked. I was charged for this repair because it wasn't under the other fuel system recall. To have a plastic piece that is prone to breakage above such a powerful engine is not safe.

Fuel tank started leaking fuel enough to drip all over engine and exhaust. Was able to stop bike before fire started. Brought bike to dealership and was able to replace. Dealership said that the fuel pump cracked and was leaking under pressure. Seems to be a common issues with all of the 2005-2008 bmw k1200s motorcycles. Bmw dealership has not filled for a recall to fix all the affected motorcycles yet.

I could smell a very slight hint of raw fuel, first thought it was a fouled spark plug, so I decided to limit use of the bike until I could get the plugs replaced. I was riding the bike to my local storage, less than 3 miles when I stopped at the gate to enter the code I noticed that the smell had become very strong, I pulled up to my unit and notice a large quantity of fluid running out from inside the bike, at first I thought it was coolant then I realized it was fuel and shut the bike down. I called the bmw service center and they were aware of at least two other bikes with a fuel leak issue, I started to research the issue, I found that a female quick disconnect fitting once installed starts to crack the fuel pump flange. I have removed the tank and found severe cracking around the quick disconnect, as it turns out this is a well documented defect by other bmw k1200 s&r bike owners also it seems that bmw is possibly aware of this and have yet to do a recall or service bulletin that I know of, my reasoning for this is that they (bmw) apparently have started to reinforce the opening for that fitting with a metal gusset to prevent the cracking and from what I have read that's how the replacement part comes. I feel pretty lucky that the unit did not catch fire. I have ordered new parts, to the tune of $800.00 that includes a new heat shield because the one on the bike is saturated with fuel. The tank sits directly above the generator, this leak is not static it happens when the unit is under power.

My motorcycle started leaking gas in the middle of a day ride and progressively got worse, so that by the end of the day, gas was pouring out onto the side of my engine and onto my boot, pant leg and forming a good size puddle on the asphalt where parked. I ended up having to replace the entire fuel pump assembly ($550 for the part, $850 total cost installed). I want bmw USA to recall this part and stand behind their product. There are multiple internet threads of people complaining about this issue. Many bmw owner's lives are at risk of catching on fire. I have spoken with mechanics and they agree, this is a defect in manufacturing.

Fuel leak from fuel tank flange. This complaint is the same as the others, namely the fuel tank flange cracks and allows fuel leakage under pressure which allows a significant amount of fuel to spray and subsequently drain down onto the alternator and then down the side of the engine and out the bottom. There is a heat shield glued to the bottom of the tank which becomes unglued when saturated with gasoline. This shield then falls onto the top of the alternator, thereby making contact with the foil-side of the heat shield to the alternator. In the event of a spark from the two materials making contact, there would be a high probability of a fire starting under the fuel tank.

The gas tank started leaking fuel. There are small cracks around a plastic fitting that is attached to the fuel tank. The fitting is attached to the fuel pump that sits directly above the alternator.

Tl* the contact owns a 2006 bmw k1200 s. The contact stated that while parked, he noticed a strong gasoline fuel odor and leaking gasoline on the ground. The contact inspected the vehicle and discovered that the fuel assembly face plate was fractured and was leaking fuel onto the engine. The contact applied a plastic weld to the fuel assembly face plate and after some time the failure recurred. The contact replaced the fuel assembly face plate and the vehicle was repaired. The approximate failure mileage was 20,000.

I noticed the smell of fuel in my garage a few weeks ago and thought it was one of three vehicles in it. I went for a ride this past week and after parking it in the garage I notice a pool do fluid under the bike. I stop to take a look and identify the fluid as gasoline. I took it to the dealer and they tell me it is the fuel pump disconnects that are leaking. These cracks are leaking fuel onto the motor and alternator creating a fire hazard! I have no doubt that this would have eventually lead to a fire that most likely would of lead to severe bodily harm or death! I am sure bmw is aware of this problem as they have updated this part on their new bikes but haven't issued a recall. All evidence shows that bmw is aware of these inherent design flaws in this model motorcycle but refuses to issue a recall putting the public as risk! I believe the federal safety agency needs to take action forcing bmw to properly address these known issues."

I was preparing to replace a defective airbox, a problem that bmw still refuses to issue a recall for even though bmw has updated the part in later model years, that was causing erratic and unpredictable throttle control which made the bike unsafe to ride when I noticed cracks in the fuel tank. These cracks are leaking fuel onto the motor and alternator creating a fire hazard! I have no doubt that this would of eventually lead to a fire that most likely would of lead to severe bodily harm or death! It appears bmw is aware of this problem also as they have updated this part as well but haven't issued a recall.
