I have a 1981 Suzuki GS750L. Not sure where the vacuum line from the carb hooks up to. Bike has not run in 20 years. It was a basket case. I am putting it back on the road. I see there is a vacuum...


The petcock has a diaphragm and needs a vacuum to allow fuel to flow, It is a safety fuel shut off, if the engine stops NO VACUUM, NO FUEL to carbs, there is usually a vacuum take off on the inlet manifold pipe between the carb and the engine. Hope that helps

Two tubes leave carburator and goes to gas tank. One has come loose and I dont see where it goes


1 tube is a fuel line and 1 tube is a vacuum line

The big one is the gas line which goes to the petcock.

The smaller one is a vacuum line which also goes to the petcock.

That is a vacuum operated petcock, which works off the vacumm off the intake side of the carb.
the intake side is the engine side, the other side of the carb is airbox side.
There should be a nipple sticking out of the carb on top on the intake side.
If not then the nipple is on the intake boot itself, on top.
The intake boots are on the engine side of the carb and the airbox boots are the opposite side.

Troybilt TB90BC fuel line schematic? I have replaced fuel lines that degraded with age and am uncerttain about the correct hook to tank, carburetor and primer. A diagram would help


easiest way to tell you is that the primer is there to pull the fuel through the carb. so fuel filter line goes from tank to carb, then from carb to primer and then back to tank as a return. if you forget which is the in line for the carb just hook with gas in a jar and try sucking it out of the jar. put filte rin a jar. and run line to carb , then line out of carb to primer and line back to jar as a return. if it pulls freely and fills the primer bulb your ready to go. if it pulls hard or not at all something is wrong.

81 650 gs whrer do the fuel lines go from tank to carbs


if this is the model i am thinking of it is a twin and has two carbs...one fuel line down to a "cross-over-pipe" ( one fuel line hooks to a "T" type splitter) that then sends fuel to both carbs. it sits in center of the two carbs.....What ypu will have that looks like fuels lines but one is a breather tube, the other is a vacuum line..
so only one fuel line down to carbs....thats if i remember the models correctly.

I think someone hooked up fuel lines wrong. The bike runs out of fuel when the fuel switch is on. Both lines out of tank go to secondary tank and bottom line on secondary tank has fuel filter and goes to...


not that familiar w/Yamaha,but disconnected vacuum hoses may connect to fuel petcock at tank.I know Honda uses a system that only allows fuel to flow when vacuum is supplied.

Replacing fuel tank on craftsman edger and other fuel lines.......do not understand where to hook fuel lines back up?  any diagrams?


ok If you have a Walbro WT series carb "without" a built on primer bulb here it is. First off if the fuel lines disintegrated you MUST disassemble it and clean it out. The MOST infintesimle speck of gas line trapped, can allow good prime and bad operation. OK? Don't be lazy on this. Just be delicate removing the flaps gasket and diaphram. ZAMA GND-12 Is the replacement Gasket and diaphram kit fot that carb. Use a cleaner, compressed air or blow good thru it. OK Now...Primer bulb, Carb, and Fuel tank, re connects: Smaller Diameter line comes from Gas tank (Connect filter screen to this in tank) to the short Straight brass carb connector. Primer bulb suction goes to the bent carb brass connector. If small line brings fuel "in" this other line sucks it back "Thru the primer bulb" and the blow side of the primer bulb sends it back to the fuel tank! So...Small Line brings fuel "TO/IN" carb thru short brass connect on carb. Other carb connect goes to bulb suction "IN", Then primer bulb "Pressure OUT" goes thru the larger tube "back to fuel tank". Trust me I know how frustrating a simple diagram is to find online fo this set up. And if you have a carb problem on top of the hook up uncertainty you got frustration. Not only was online help hard to find (Mfg...etc NFG at all!) My local repairshop in BBrook NJ could not tell me how!!! and thats no lie! Walbro has a "generic" carb diagram but no "hook up info" specifically. Poulan don't list it either. And these things routinly fall to pcs. all 3 of mine crumpled together on yr. 3 of use.

Carburetor fuel flow


Hi and welcome to FixYa,

Initially, to your queries:
  • hook up all the vacuum lines - yes or cover/plug all
  • to stop fuel flow - hooking up all the vacuum lines or covering/plugging them would be technically correct but will not stop the flooding/fuel overflow;
  • run correctly - with constant overflow/flooding, it will not run correctly.
To my knowledge, overflow could only be caused by:
  • faulty valve pins, worn out rounded pyramids, necked/indentations on the surface of the rounded pyramid, cracks (rubber type);
  • worn out inlet port;
  • dirt, sand, foreign object lodged against inlet port hole;
  • mis-adjusted floats;
Which would mean, go to do it all over again.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
