Tim -

I'm not sure about a 280, but on my 240 the sender has a notch at the 3 oclock position that mates with a bump in the tank opening (i.e. it can only seat properly one way). In that orientation, the wires are about 1 oclock (white) and 5 oclock (black). The float moves up and down (not sidways). Just to check things out before you install, try swinging the float all the way in one direction and watch the fuel gauge (wires connected) then swing the float in the other direction. The guage should also move from full to empty. If no notch is available to align the sender, then make sure that you install it so that the gauge reads full when the float is up and empty when down.
