actually, the fuel line comes out of the bottom of the tank, left side, center. thats where the petcock is.
that looks like the right side tank mounting ear. there should be no gas near that. only fluid near that is coolant (thermostat housing is just above and to the right of there)
all of that said, tank removal to investigate is a breeze. I can probably take mine off in 8-10 mins max. and thats only because my seat mount is not the same as stock
remove vacuum line at petcock (either from petcock or the left carb)
remove 2 fuel lines from petcock
disconnect vent line from bottom rear (may have 2, may not)
disconnect the electrical connection there for the fuel level sender (2 wires i believe, should be right next to the vent line)
remove 3 bolts (one rear center, one left, one right)
lift tank off the bike.
NOTE: pay attention to the hardware that the mounts have on them, that needs to go back into the same place, front and rear are not the same
