I took my tank off to work on the wiring, I didn't notice there were 3 lines on this. I know one is the vacuum line to the petcock, one is the main fuel line, but there's one thats a couple feet long, is this a vent line or something?

Its a drain should the gauge sender unit spring a leak.1978 GS1085.
Just remember, an opinion without 3.14 is just an onion! -
The drain tube slips over the small nipple on the "gutter" at the bottom 1/2 of sending unit , runs along the frame to the ground, away from the exhaust !!Comment

I have no idea which model you have but there should be one (or 2) vent lines coming from between your carbs. Since you mentioned your gas line and your petcock vacuum line, I'm guessing that's the one you're seeing.1980 GS1100E, the latest of many.Comment

Except that he is asking about the line on the TANK, not the carbs.Originally posted by rockford View Post
Shameless, as the others have mentioned, that is a safety drain line, in case the gasket around the sending unit happens to leak.
And this is one of the few times that specific model information does not matter. Any of the GSes that have a fuel gauge will have that drain line, and it works the same way for all of them.

My confusion came from reading the post but not the title. My bad! (I still can't figure out why the 2 petcock lines were even mentioned)Originally posted by Steve View Post

Be sure to route all those overflow lines (either from the carbs or sender unit) pointing away from your rear tire. Some guys got these lines dumping right in front of the rear tire. Spring a leak and you are going to start sliding all over the place.Ed
