Tank Install help...Gas Lines

[Streetdremz]

Got a new tank for my `82 850GL. Problem is the old lines were badly damaged so I can't figure out were the new gas lines should be connected.

Petcock has 2 valves for gas lines and the the fuel Gauge/Drain has 1 valve. Problem is I only have 2 visible gas lines both running to the carbs: 1 to the front and 1 to the rear of the carbs (rear has some sort of fuel filter nipple).

So I assume one of these has to be a breather tube but which one. I've checked Babbitts and Bike Bandit but they were no help. Does anyone know which gas lines need to be connected were?

The bigger hose is the fuel supply to the carbs, it goes onto a "T" between two carbs, probably the center two. This would be the one that had the filter on it. Filter is not necessary if the tank is clean inside, if you do use one get one made for motorcycles, the automotive ones won't flow enough fuel without a fuel pump.

The smaller hose is vacuum from the carb to the petcock, it turns the fuel on only when the engine is running. The lower end will go onto a barb on the side of one of the carbs, not sure which one on your model.

The drain from the sending unit just goes down under the bike someplace safe in case fuel leaks out, which shouldn't happen. If fuel leaks out of this hose, you will need to fix the leaky sender.

Perfect! Thanks for the fast response. Going to see if I can get her fired up today.
