Fuel leak - DL1k

Went to ride today, had the bike idling in the driveway, went out to get on and smelled gas?? Looked under the TB's and see drip, drip, drip...hmm? Looks like its coming for the 1.5" fuel line that connects the TB's. I'm in the process of taking all apart and have got up to removing the airbox.

Holy crap, can't believe all the stuff that has to be removed to get this far. I followed MS's stickys on removal and tank and all good. Have to remove RT side fairing to get to front airbox clamp and since I have Givi guards, its a bit trickier to get the fairing off.

This might explain why my bike had trouble pulling top gear on the freeway last week after a 360mi spirited ride.

Any input at this point would be appreciated. I'll take pics and report back.

here it is. Doesn't look bad, but it can be seen where the fuel stained the front fitting. Hard to tell from pic.

I'm hoping I can just remove the mounts to the top of the TB's (2 screws each- see in pic) vs having to separate TB's and go that route. Hopefully someone will post up with some thoughts. I'm in no hurry.

Thanks.

If the hose isn't split, snipping off the the stock crimped clamps and installing FI rated screw clamps will usually cure the problem. The part that covers the space between the ears of the clamp is vital. Regular hose clamps and the stock clamps don't have it but the stockers have a smaller opening and usually work okay.

Hose looks fine but hard to tell until I take off stock clamps as you suggest. Seems to be seeping under the clamp/hose and not damaged.

Not sure what you mean about "space betwen the ears....stock clamps don't have....."

Thanks for the quick input.

I mean the curved part next to the screw shaft between the nut and the head. I guess that is pretty standard now. Just make sure whatever clamp you use is rated for fuel injection pressures. Screw band types won't work properly for example so don't try these.

Thanks for the explanation. Noted about screw type not being suitable. I assume screw type doesn't provide equal pressure needed to secure?

Just checked Suzuki fiche to see if I could order the clamps and fuel line piece from OE. Ha! I see you can only buy the fuel pipe assy for $148.00!

Off to the auto parts store to see about clamps.

Screw bad types can't apply enough pressure or properly conform to the outside of the hose. Good pressure needs to be applied all around with no unpressed areas. Getting the right size is also important for that reason.

As I look at this further, I realize the stock type clamp still requires the hose to come off and also a special crimp tool for the clamp. I did a google search and found the clamp is "single ear step clamp". I went to a few local auto parts stores in town and no one has this type. I've found a few online places and will make some calls tomorrow.

Worst case, I'll replace the entire fuel pipe piece.

I wouldn't use a crimp type. The type in my first picture would be my probable choice and I think you can get it on without removing the hose. I've never replaced that hose but it doesn't look like a fun job.

Ok. I also see that type listed as ok for FI. I'll look for those tomorrow.

Thanks again Greywolf!
