The mirror didn't help much, but removing the side skirt panel stay gave me a good view of the top of the tank. The fuel guage unit and connector are way back on the tank - the stream of gas is squirting from one of the metal pipes coming out of the Fuel pump assembly toward the front. It looked to lead to the filter so I assume it's the main fuel line.

The sevice manual gives no indication of the distinction between fuel pump assembly, packing, and the two lines leading out from the pump area. As the 'pipe' curls over the side of the tank and heads to the front it attaches to a flexible hose after a few inches. Does the other end just go to the pump or is it part of some of the other pieces in the assembly?
