Just when I put the pop corn down.
There is no 'overflow' fuel line per se coming from the fuel tank. The two hoses are the tank vent (w/roll over valve) and the scupper drain.
On the 05+, the vent hose connects to the front tank fitting, and the rear is for the filler cap scupper. Someone needs to verify if that is correct for an 01. I'm assuming that is your ride since you have not said otherwise in your profile.
Verify that the QD is connected correctly, and the two hoses are on the proper fittings and are not kinked/pinched, and let us know how it goes.
