fuel gauge wiring

I am most likely over explaining and thus not making good sense or you may have a slightly different configuration.

no, you make perfect sense, we just have different setups.

my gauge has a black/white wire, a grey wire and an orange wire. my tank sending unit, on the other hand, has a black/yellow wire and a yellow/black wire. now acording to the wiring for my bike, the black/yellow and the yellow/black run to the gauge, but the gauge has black/yellow, orange and yellow/black. and orange. i hooked the orange to the orange from my bike, and the b/y and y/b to the corrosponding wires. but i also had a grey that i ran to a common ground i had.. i'm ognna have to take off the gauge and investagate.
 
OK I found more detail. Save this diagram to your PC and open.
The grey wire is positive for the gauge lamps and goes to the positive thats there when the lights are on. Both the lamp and the gauge have a black/white to negative or ground and may be be combined into one.
There must be a yellow black wire that goes back to the tank sender unit. At the tank definitely two wires a black/white to ground and a yellow/black to the sender.
Have a look at the diagram attached
 
Yeah, the gray is for gauge-lighting, and if this is your 1100 you're working on, then the gauge lights are probably on whenever the ignition's on. The gauge itself only needs 12V to the gauge(wire w/orange), and a variable ground/potentiometer/tank sender between gauge ground(black/black & white wires) and the gauge.
 
well.. the gas gauge has mysteriously started working again. since the continuity checks out on the lines outside the tank, i am starting to wonder if i've got a faulty connection inside.

That sounds good. If it's not the wiring, check this procedure blow to adjust the sender unit. If the wiper does not have enough tension on the sender resitance windings it can lift off and give intermittent readings, sometimes only at some different positions.
