The one coming from the fuel sending unit should be a square black plastic snap-on thing about 2" square with a hose attached to it. The hose just kind of winds it way down to the swing arm pivot thru a clamp in case it ever leaks it would be directly to the ground.
The nipple on the rear of the gas tank (assuming this in not a CA model that has three) drains rain water or spilled gas onto the ground and pretty much follows the same path as the one above.
Make sure you have all 4 of the rubber bumpers while you are in there too. Two round bumpers slide into holders on the frame, the third is a large about 5" square block rests on the frame at the rear of the tank, and a forth one is "U" shaped and goes over the frame right where the coils are. Make sure you have the correct rubber parts and washers on the bolts that secure the tank also.
