84 GS750E question

[Anonymous]

Hi everyone,

Helping a friend get this 84 GS750E going. The tank was removed to clean the carbs and we need to figure out were all the lines under the tank run to.

If someone could help us out that would be great.

Petcock has 2 outlets, 1 small one -pulse ? running to the front of carb #2
1 larger one - main gas line? running to the back of carb #3

Right side of gas tank, 1 smaller outlet, is this just a vent line?

Center of tank, vent line?

Thanks for taking the time to read this.

If you have any pics to show were everythings goes that would be great.

Great site

Small hose goes between the front-facing vacuum fitting on the petcock and vacuum fitting on carb 2; large hose goes between the large rear-facing port on the petcock and the gas inlet fitting behind carb 3. The petcock is vacuum activated. Prime is straight gravity flow. Run is diaphragm activated using engine vacuum.

The fuel guage sending unit has a vent line...likely this is the one you find coming from the right side of the gas tank.

Not sure about the 'center of the tank' one...could it be the crankcase vent line which comes off the top of the valve cover and goes to the front center top of the air box? With the tank on the bike it would look like it is coming from the center of the tank.

There should also be two vent hoses coming from the rear of the carbs.

The line from the center of the tank is the overflow drain line for the tank. Make sure it goes far enough down that you don't get gas on a hot engine part when refueling.
