NOT the standard fuel line between the throttle bodies issue...or maybe it is... ;/

Hola All!

New member and new owner of a DL650 K4. 32k miles and in great condition. I don't know the service history so I figured I'd have to do some maintenance on it soon. It's been 3 weeks since I've had it aaaaaaaand gas leak.
I've searched the forums and found the common threads about that fuel line between the throttle bodies.
I put this out here only because it doesn't act like what I've read in the threads.
It just started leaking. Went for a 2 hour ride on Saturday, was getting ready to ride on Sunday and when I went out into the garage, the smell of gas hit me. It has a slow steady drip.drip.drip from under the tank onto the radiator.
I'm going to pull the seat and tank off later tonight or tomorrow and hopefully find that it is indeed that same fuel line, but just in case...anyone have any other ideas? Much appreciated.

Just to verify, is it dripping on to the radiator or the oil cooler? The small hose you are referring to is about directly above the oil fill hole. If you get down on that side of the bike and look up you can see it pretty easy. I attached a terrible picture I just snapped. Look for the square shaped ends in the picture. The hose is maybe 1.5-2” long.

I can’t see how leaking fuel would get from there all the way to the radiator but maybe it could.

If it is in fact leaking on to the radiator, I’d be more inclined to suspect the tank itself is leaking as I don’t think there are any openings for hoses that far forward.

That is just my $.02 worth.

PS 2004 is the best year!

I went back out and took some pictures to be sure. Definitely not from the small hose. With closer inspection, I noticed discoloration on the underside of the hose that runs from the radiator and bubbling of the paint on the radiator itself. When I tried to dry off the gas from the radiator, it slid off... Me thinks this bike has had this issue for awhile. What does not make sense is the time in between. I bought the bike on 6/21. No gas smell, no leaks, no anything. I've ridden it around 1,200 miles since then and on day 23...boom. Hello Mr. Leak.
I don't know what changed. Ah well, I knew it was going to need some work for its age and mileage. I've only ridden around the block a few times since Sunday and I'm jonesing to go ride...lol.
So, you said gas tank? What connections are directly above that spot? Got any schematics?
First pic is the underside of the radiator. Second pic is right side, water hose. See how gas is dripping from the fairing to the top of the hose?
Thanks Bud!

Man that sucks...

There are no openings above that spot. The only openings on the bottom of the tank are the fuel pump and the overflow / vent. The fuel output hose connects to the fuel pump. Those are all toward the rear of the tank though. The overflow / vent hose drains down by the rear brake pedal. There is nothing towards the front.

Here is a pic from when I replaced my fuel filter a few months ago showing the bottom of the tank. I guess the gasket for the fuel pump could leak and dribble down towards the front or something. Either that or the main hose (replaced mine a few years ago cause it was getting damp with fuel soak thru but not actually leaking).

Hopefully it turns out to be something easy like a gasket or hose.

The metal tube with the gray clip is where the main fuel hose connects. The other tube towards the outside of the tank is the vent / overflow. There’s a rubber hose supposed to be hooked to that and it snakes down by the brake pedal.

Just a thought, but a leak can run laterally following something like a frame rail or metal surface, before it drips and falls vertical.

Three suggestions...

1) light it with a match and watch which way the flame goes.
2) remove the tank and have a look-see
3) ignore number 1

Are you sure you are only chasing one leak ?

When restoring tractors many use coolant as a gentle way of removing paint, could you also be looking at a coolant leak ?


Stuffing paper towels in gaps then looking for wet spots can help pin down a leak.

You may need the motor running to find high pressure leaks.

Don't rule out rust spots in the tank, water sits in the bottom and causes rust holes.


Good luck.

Thanks for the pix, bud. Very helpful. I know that the guy I bought it from said he had replaced the fuel pump...maybe it is a gasket or a hose like ya said. We'll see. I plan to pull the tank this evening.

Shoot...had not thought of that. I figured the bubbled paint on the bottom of the radiator was from the gas...
I'm going to do a double check with the paper towels and look for what you said.
Is there anything else I should look for/check/change while I have the tank off? Thanks!

For sure look at the air filter. If it is even close to dirty replace it while tank is off.
