Go to www.searspartsdirect.com and with your model number you should be able to find explode parts views of that trimmer. Filtered line to primer, primer to straight inlet on carb, angled outlet on carb back to tank. That might work. Not sure without part number.

How to route fuel lines for a weed eater GHT-17 type1 carb. It has only one fuel inlet on carb, its a walbro w1221a.


It would a WT-221. You got fairly right that one is a vent line and it does feed up into the handle and is vented out thru it; although, you may to add a check valve to it. I repaired a few of these and the ones I did all leaked out of the vent line until I added an Echo line vent to the vent line.
The problem I had was that the vent line not only allowed air into the tank, it allow fuel to escape thru the vent line when the tank pressurized.

Walbro wt-141 changeover to wt-629


If the carb has two connections then it is designed to work with a primer bulb, the fuel inlet will be nearest to the pump cover, the alluminium cover held with a single central screw, you can either get the correct carb for the machine or use a short rubber tube with a blank in the end ti close it off.

Need diagram of fuel lines from tank to primer bulb and carburator on a Poland chainsaw model 1950 wood shark


There are 7 different types of the 1950 model (types 1 - 7) and it came with one of these 2 carbs Walbro or Zama. The carbs are different as are the fuel line connections for each one.
Although this video is for the promer bulb you can see the routing of the fuel lines.

You will have one line from the fuel tank connecting to primer bulb the 2nd line going to the carb. If you connect it backward it does not pump fuel into the carb.

(FYI Types 1 - 5 all have the same fuel line routing.)

Walbro WT891 carb on a Craftsman chainsaw. Carb is brand new, all fuel lines and fule filter replaced. I prime the carb with the little plunger, chainsaw starts up and runs out of fuel within 30 seconds....


Who connected these hoses? the normal routing for a machine with a primer is like this, the fuel hose from the tank with the filter on the end goes to the carb fuel inlet nozzel ( not to the primer ) nearest to the pump cover ( cover on carb held with one screw ) the pipe from the metering side of the carb connects to the shorter nozzel on the primer bulb ( suction side ), the longer nozzel on the primer ( pressure side ) connects to the pipe going back to the tank, just remember the primer pulls fuel from the carb,into the bulb, and pushes it back into the tank, it is not actually a primer it is a purge. because it is connected this way it is impossible to flood the engine no matter how many times the bulb is pressed.
Let me know if it starts and runs.

Which fuel line "port/inlet" on the Walbro wt-380 goes to the fuel tank? It's on a Craftsman 25cc Gas "Weed Wacker" Line Trimmer purchased in 2002. It has Walbro WT-380 carburetor with external primer...


Usually the line with the filter on it that comes from the tank goes to carb. inlet first which is most likely close to the bottom side of the carb.nearest to the engine,then the outlet or return line on the carb.goes to the inlet side of the primer and the outlet side of the primer goes back to the tank. The primer draws fuel through the carb to the primer to the tank if its not? then correct the line connections until it does

String trimmer, fuel lines disintegrated, I need routing.


The Walbro has two connections on it for the fuel line. My Walbro has one connection on the side of the idle screw and main fuel adjusting screw. This connection hooks up to the suction side of the primer bulb. Usually the shorter stem. (You actually **** fuel through the carb instead of pushing it through.) On the other side of the carb is the other hook up. It draws fuel from the tank. This line will connect to the side of the tank that has the filter. The other side of the tank is your return and it hooks to the other connection on the primer bulb. Usually the longer stem.

  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, the output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.
Take lots of notes and a few digital photographs will help with reassembly. HTH

Trying to put new fuel lines in all around... bulb has two connections, tank and carb. carb has two connections, I imagine that the tank/filter line goes into the carb, carb then goes out to bulb, bulb...


Fuel routing:
Tank to carb (filter on free end in tank, replace annually)
Carb to primer (primer sucks fuel through carb)
Primer to tank (primer returns excess fuel to tank) HTH
