Occasional Fuel Leak 07' DL1000?

I have an 07' DL 1000, 17,000 mi. Every now and then, usually if she sits a few days, when I start up I have a fuel leak. It started last winter, happens on and off sometimes doesn't do it for a month or more. It leaks pretty good things get wet, fuel on ground.

I Replaced fuel line that runs from tank to fuel rail this spring and thought I fixed it but it did it again yesterday. Hard to see but it looks like it comes from connection between fuel line and fuel rail I think? But really not sure fuel bouncing everywhere, and it doesn't do it if you take stuff off and look for it!!!

Runs sort of rough too, wanted to stall while on stand (never usually happens) exhaust smelled rich but not sure odor was exhaust or raw fuel evaporting off engine. Just smelled hydrocarbons not sure which ones.

If you shut her off and start again it usually quits. Yesterday it seemed to do it when I restarted but till I got to the gas station (7 miles) it had stopped, to never do it again the rest of the day. Yea I rode with a fuel leak, but was trying to see how it was behaving and it quit as it usually does.

Went out this morning, no leak.

Two bad fuel line O rings?? Ethanol eating the gaskets ( Ohio Fuel, U can smell the E )? Pump creating too much pressure now and then?

The most common reports of leaks except for user error at the tank connection are the hose connections at the rails. The second most common involve the O-rings at the rails. Replacing the crimp style clamps with hose clamps rated for fuel injection hoses usually solves the problem.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

I have had this problem too

My 2003 DL1K started doing this last year. The fuel cascades down into the V between the cylinders. Once warm or ridden the problem goes away for several months.

I will take Greywolf's advice and get rid of the stock connections.

2 or 3 times (not recently) my 07 Vee has puked fuel out of the overflow and dribbled along the crankcase leaving telltale streaks of ethanol corrosion

Grey wolf has guided you wisely. Very common and easy repair. This leak will come and go but will get worse. This was my first repair to make.
