My apologies for being away from the board for quite a while. Life. Y'know?

The subject is a 2000 K1200LT with about 50,000 miles.

The last two or three times I've ridden my bike, I have had a small gas leak. Apparently very small. It's on the right side because my right shoe smells like gas... but not enough to make it "wet" with gas (like the leaky carbs on my 1972 R60/5).

I have noticed no smell of gas in the garage, no gas spot on the floor, no other indications of a leak -- apparently it only leaks when it's running, or maybe with the bike a certain angles.


Does this sound like a failed quick disconnect fitting? Or does it sound like something else since it's apparently only leaking while running?


Thanks,
j

change out the QD's to metal ..
the lines are pressurized and will shoot gas out when the bike is on. beemerboneyard has decent prices for metal QD's.

Remove the right side tupperware, bring it outside and fire it up. You should see the problem right away.

I changed my plastic QD's couple months ago with beemerboneyard metal QD's. Not hard to do but take your time working the old ones off the fuel lines as those lines are getting up in age.

BYW; Do one at a time so you are sure to keep the male and female parts on the correct ends of the fuel line.

You can just replace the male half only with the metal ones from the dealership. It is probably best to just change both halves to metal while you're in there. I would not ride it until it's repaired. When it goes all the way out you get 50 PSI of fuel. It can catch fire. If nothing else it will stink your boot and leg up big time.

Definetly sounds like QD's mine started out as just smelling the gas then went to leaking enough that when I put my foot down it slipped on the asphalt. This got my attention and I replaced both with the metal QD's problem solved. Easy fix and relatively inexpensive compared to a FD repair.

Here is 1/2 of what you need - took tank off!!



The plastic male part breaks or should I say cracks - but not all the way.
Then when the fuel pump comes on and pressure is applied to the lines they
will leak. I always thought it was rough handling by guys with big mits that
broke them I was very careful and mine just snapped with almost no effort
- aged plastic, poor material selection and design.

If you can get a clamp tool and clamps that do not require the screw connections
like shown in the picture - bit if a hassle getting them plugged in and fitting properly
in the allotted space - even the steel ones!!

I had the same problem on a recent trip. For a few days I smelled fresh gas but could see nothing. Going from Livingston Mt down to Gardiner Yellowstone the smell got worse, stopped, saw nothing. Figured it must only be leaking when running. I stood on the right side and started it, looking in I could see wet gas running down the side of the case. Took off the plastic and found a bubble in the fuel line with a pin hole in the center of the bubble. Sprayed pretty good when it was running. I cleaned and taped it well with electrical tape and put a hose clamp right over where the hole is. Still that way now.

Years ago, it wuz recommended to install the QDs in reverse orientation to each other. That way, if you have both lines apart (removing fuel tank, as an example), you won't get them confused when re-connecting the lines.

The model year 2000 LT did not come with QDs, although the PO may have installed QDs for easier maintenance.
Anywhoo you should remove the right side panel and see what is going on. You may have a bad fuel line, or maybe the gasket at the imperial (big round thing at the bottom of the tank on the right side of the tank) although you said it leaked only with the engine running so I would think it is a line or QD, or maybe just a loose clamp on the fuel line. A visual inspection shall reveal all...;)

My 2005 LT did that to me just this last Tuesday. Amazes me, BMW has known about the failure rate of these since at least 2001 as there had been a recall on that bike, yet they continued to use the same plastic QD!

Anyone know what they are using on the new 1600s?

I had to have mine changed out on the road this summer. The dealer I went to didn't even have the plastic ones to replace with and suggested to change both out to metal. $150.00 later and we were back on the road.

Thanks, all. Yeah, my tupper looks like Wardenross' pics. When I have some time ( :histerica ) I'll dig in there and see what's up. It's getting to be cage season anyway.


A couple months ago, I had part of the front brake line fail. The front brake lever had started to feel really mushy, then one day, it just came all the way to the grip. I rode very carefully to my indi using just the back brake. It took him a while to find which hose it was, but I think he said the hose broke at a fitting.

Maybe I missed the item in the technical handbook that said "replace ALL rubber bits every ten years". I can't wait to see what poops out next.

Thanks again,
j
