I have a 1982 GS 850. I have two rubber lines coming out from under the gas tank that don't connect.?
One line comes from the petcock and the other comes from a silver electronic moduel just opposite from the petcock. I was wondering if they were suppose to be connected to anything.
--The "electronic moduel" is the fuel level gauge. It has a cover to protect it from getting damaged when removing and installing the fuel tank. When water gets in, or moisture accumulates in the cover, it drains out the hose. The hose doesn't connect to anything. It either just hangs there, or if it's long enough, it's gets routed to the ground.
--The petcock is a vaccum petcock. Vaccum from the engine while it's cranking, sucks a diaphram open to allow the fuel to flow (a saftey feature to prevent the fuel from flowing in case of an accident and the bike stops running).
--If the petcock has 2 outlets, one is the fuel line to the carbs. The other is the vaccum hose and connects to the joint between the #1&2 carbs.
--If the petcock has 3 outlets, then the 3rd hose is just a breather hose, to allow air to enter and escape from the diaphram chamber. It doesn't connect to anything. It just hangs there.

I have an '87 GSXR with vaccume actuated fuel petcock not opening...?
I had the tank off of my '87 GSXR 750 for paint. Would not start when re-assembled. After much aggravation and trouble shooting, it turns out that there is no vaccume at all at the line connected to the petcock, so it is not opening. Bench tested the petcock, and it opens with vaccume. The vaccume line is good, connected securely, and not obstructed. I can blow air back into the carb fitting through the vaccume line. Anyone have any thoughts?
You probably have the wrong hose attached to the petcock.
Remove the hose - put your finger over the end - crank the engine - should feel a vacuum.
