I'm leaking gas and I can't figure out where.
Haven't been able to ride all week as I've been feeling sick. Finally today I've been feeling ok so I decide to take my tank off to shrink wrap my wires.
I put the tank back on and within a few minutes a small puddle of gas appeared.
So I turn the gas petcock off and feel around looking and feeling for a gas leak.
NOTHING!
Turn the gas back on and again the leak, felt around petcock, and visible part of gas line NOTHING! So I take air cleaner and backing plate off and still see nothing.
Being as I haven't rode it all week and had the petcock off I don't know if it was leaking before hand. I felt all under the tank and it was dry as a bone.
I'm at a loss here, it looks like it is just leaking out of the bottom.

Sul beat me to it. If your float is stuck due to trash in the carb bowl, it will keep trying to fill itself, when the level of fuel reaches the overflow port, it will dump out thru the small line running from your carb down to the ground. If that's it, drop your bowl and clean it out. :up:

Does your tank have a vent line at the right rear? If so then when you removed the tank you could have drained some fuel out of the vent. Both of my Big Dogs have been Kalifornia models that have the tank vent (vents to the charcoal filter).
If you don't have the vent then you must have a stuck float although seems odd that it happened after you removed the tank without any other agitation. :confused:

Hope you get it figured out,

Same thing happened to me during my sporty build where all I did was swap out the fuel tank. I had let the carb dry out and that must have messed up the adjustment on the float or something cause the first time I turned on the fuel, it filled up the bowl and then started pissin out of the overflow. I took the bowl off and made sure there was no trash in there, fiddled with the float a bit and it was good to go after that.:confused: :confused:

Thanks guys,
Yea, it was coming out that overflow tube. Couldn't see it at first until I put a mirror down there and saw it drip. I banged on the float bowl it a couple times, then took it out and blasted down the freeway, came back, had 2 cigarettes and no leak during that time...Just like my old Barracuda...Bang on the float bowl...

This was discussed a month or so ago, so I guess some Dogs did have the charcoal filter.
