1979 GS750 Fuel Tank Sensor Vent Line?

[Guest]

Trying to figure out where the black hose connects to?

Thanks

Also on the carb vacuum line....read in two places on this forum that the petcock goes to # 2 and one place that it goes to # 3?

I have VM26 Carbs.

Cant help you with the first question, but the manual for the 750 says the vacuum line goes on carb #3.

The hose is an over flow in the event the gasket leaks. It hangs down toward the center stand so and fuel doesn't flow on to the hot motor. I'm not familiar with VMs.

I will concur with both posters. On the VM carbs, the vacuum line connects to #3 carb. Note that carbs are numbered from left to right, as you sit on the bike. #1 is under your clutch hand, #4 is under your throttle hand.

The "vent line" as you call it is actually a safety drain, as Charlie G mentioned. In the event the sending unit gasket ever fails, that hose will divert gas away from the engine and dump it right in front of your rear tire.

Thanks for the info. Really helps.

This is my 1st Suzuki. Picked it up for $380. Was told it only needed new jugs...then I found the trans sprocket shaft totally stripped and in the middle of reassembling the engine. Waiting for a few parts before I can put the case together.
