Needing to remove my tank ( 06 Roadster ) for repairs. I have fuel line disconnected and valve turned on, but the fuel won't come out. What am I missing?

 

Fuel will drain by vacuum only.

 

The vacuum feature only works when the engine is running. I recommend a suitable can to contain the fuel, plus a large funnel, remove your tank from the bike and then carefully drain the tank via the filler cap.

 

Ya you have a vacuum petcock. I prefer to use a siphon. Quick and easy with no mess.

 

Pick up a cheap siphon hose pump from Harbour Freight or your local auto parts store for around $5.

 

When I swapped out my tank I pulled it first, removed the fuel pump and drained it into a clean bucket. Was quick and easy and allowed me to completely drain the tank.

 

Same method I just recently used, much easier.

 

It sounds like the OP's bike is carbureted, meaning there's no fuel pump.

 

Someone should invent a tube like device that can be used to suck out the gas in the tank. Oh wait! They did it's called a siphon.

 

Keep it simple.

Disconnect the vacuum line from Carb end, keep it connected to petcock. With drain line in a suitable container, suck on the vacuum line until the fuel starts flowing, then pull it out of your mouth and cover it with your thumb. Might need to do it a couple of times. It will work, might be a little slow, but it will work. Just needs a little vacuum/suction to get the fuel moving.
