Gas smell

[27376]

I have an 1150RT I noticed a smell of gas in the garage it seems to be coming from the right side around the cylinder. does anyone have any ideas as to where it could be coming from. I recently had my brake fluid flushed at the dealer, any connection?
Thanks John

The fuel lines connect to the tank on the right. There are quick disconnects with little O rings on the right. There are two connections to the fuel distributor assembly on the right. The fuel tank vent line and overflow line are also on the right side of the frame. All generally above the right cylinder or just forward of there. And some of this is disturbed when the ABS is worked on. So I'd try to find what's leaking and fix it.

It was the top quick connect parts on the way
Thanks, John

Thanks, JohnAre you going back with the original plastic QD or a metal one? Typically, it is the white plastic "male" portion of the QD that fails. Metal is better!

I called the dealer today and they recomend the metal ones so that is what is being sent. I guess there was a problem with the plastic

Problem with the plastic is that the male end breaks easily. However, the o-rings can go bad on either type. No need to replace the female plastic connector though.

The leak could also be caused by the crimp style hose clamps. The rubber hose material apparently shrinks, causing the clamps to loosen. You may be able to tighten the crimps with an old fashioned pair of pliers (I used jaw cutters) until you can replace the clamps.
Also, be aware that the fuel dripping on the transmission case may discolor the silver paint (not sure if your bike has that but it was an issue with the 04 GS models. DAMHIK

You might want to check the fuel lines and replace if they are questionable.

I would eliminate the quick disconnect on an RT. There's absolutely no reason to put quick disconnects on a motorcycle that requires stripping off all the plastic to see the gas tank, let alone remove it. There's nothing quick about removing the gas tank on an RT. Quick disconnects (even the steel replacement) provides an unnecessary point of failure. The fact that folks can diagnose the problem without even looking under the plastic point to the fact that this is a common failure.

I've lost count of the number of quick disconnect failures I've seen. On my GS, I've broken one male end while reassembling the bike and damaged the rubber seal on the new male disconnect while reassembling. When they leak, they permanently stain the motors piss yellow. IMHO, they are a bad idea for any bike other than a GS or R. On my RT and LT, I won't use them.

I wonder why BMW put them on in the first place, since quick disconnects add cost. It wasn't one of BMWs brightest moments.

Hmm you think like me! Actually if they made good ones that didnt fail Id be all for them. Im not sure theyre even suitable for the GS and R. If they leak and the bike catches fire (while you're riding it) it could prove very embarassing.

While I still use the quick disconnects on my GS, I always carry fuel line connectors and clamps just in case a fuel line develops a leak or the quick disconnects fail in the tool compartment. I would recommend this practice of anyone that owns a bike with quick disconnects.

I just had an experance with the disconnect on my 05 GS.
I too smelled gas in the garage after a fillup for the trip to Ar. I thought it was just because I had just filled the bike. I got 210 miles from home when gas began pouring out the left side of my bike. All over my leathers and boot. I was in the middle of nowhere, McCurtain, OK. This town has 1 store (7-11 type) No cell coverage with AT&T or Verizon. The pay phone in the store was out of order. The kind lady that ran the place allowed me to use her cell.

Thank goodness I had carried AAA for years, this was the first call. They arrived in about 30 minutes and the bike was hauled 91 miles to Ozark, AR where I was meeting my Brother from Fl. He rode up to Bentonville the next day and got me 2 quick disconnect. replaced the old broken one in about 5 minutes after I got the BMW clamp off. The spare is in my tool kit along with a alternater belt and a couple of light bulbs.

recommendation to all BMW riders
Carry a spare quick disconnect
