I took this apart a few months ago and forgot where the hoses go. I assume the hose coming from the tank is a vent hose and a vacuum hose coming off of the petcock. But I'm getting frustrated trying to hook up the fuel line to the petcock with the vacuum hose directly in the way. Any ideas? Bike is a 79 GS1000E with VM carbs.

Could not tell anything from that picture (which way is UP?
), but there should be two fittings on the petcock. The smaller one is vacuum, it will be connected to the port on carb #3 (that is the inside carb on the throttle hand side). The larger port is for fuel, it gets connected to the hose that fits on the Tee between carbs 2 and 3. There should also be vent hoses on carbs 2 and 4, they just get routed over and behind the airbox, they don't connect to anything. There might also be a hose that goes to a fitting on the safety funnel on the fuel level sender. That should be a rather long hose, it gets routed behind the engine, usually ending below the swingarm pivot. It is there just in case the gasket on the level sender leaks.

Awesome, thank you. It appears I put back of the petcock on wrong. The vacuum line should be facing towards the front of the bike (I think). But the hose isn't long enough to reach the fitting on the carb.Comment

Correct, the vacuum port is towards the front of the engine. New hose will reach the carb fitting.Larry
