Red is fuel in from tank. Blue is a vent line routed down behind engine case.

Yes, all inter-carb connectors should have fuel line on them.   The one pictured above is a vent/overflow line, and needs to be routed to drain down and away from the hot engine.

It is a float bowl vent.

If you put your finger over a straw full of fluid, the fluid will not come out until you VENT the straw by taking your finger off of the straw. Same principal.

yes i was shure it should be connected. but my 77 carbs dont have the vent beside the fuel line. guess its the one one the left side on carb 1 that serve this purpose.
