Poulan trimmer fuel line replacement - how to hook up?

Hi,Please show me how to hook up new fuel lines to my poulan trimmer. It has a primer bulb and total of 3 fuel lines. The primer bulb has an "IN" and an "OUT" ports. The caburetor has a bottom and upper ports. The long small fuel line from the gas tank has the filter. The big and short fuel line from the gas line has what looks like a vent adapter. I tried to hook up to different ways, but it only run when I put a FULL choke. It will keep running continuously on Full choke. When I turned to 1/2 choke, it die. Thanks in advance. ART

Yes, you are right. The larger line goes to the primer bulb and only goes into the tank about an inch. The coupling just keeps the line from pulling out of the tank. The smaller line goes to the carb. This line must rest comfortably on the bottom of the tank with the filter attached to the end.

The larger of the fuel lines is the main fuel line. It is the one that has the filter stuck in the end of it and runs out the larger hole in the tank to a fitting on the carb. The smaller line should be about one inch into the tank and comes out the smaller hole and runs to one of the nipples on the primer bulb. Press the primer bulb and put your finger in front of the fittings. The one that you feel air coming out of when you do this is the fitting that runs from the primer bulb to the carb. Hope this helps and good luck.

SOURCE: My Craftsman 17cc gas weed trimmer wouldn't start.

Hi There, Check the primer bulb for tare or pin holes. Replace it. Check and clean carb jet it maybe plugged with debree. Also check for spark which you didn't say. Replace with correct plug.
Note; Do not use strong cleaners on rubber seals (O rings and gaskets) They dry up and crack.
If needed use a dabble of grease on seals

Put a new carburator on and don't know how to hook


Hi janemueller...

Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.

Diagram fuel lines tank primer carbutor poulan pro weedeater


I have no diagram but here are the instructions on how it goes.
The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.

Need a diagram of fuel gas lines on a 131 poulan


Lots of research has shown a lack of diagrams on fuel line routing. Your carburetor has the purge/primer bulb on top of it. Just to help you understand how it works....the bulb uses a vacuum effect to pull fuel from the tank directly into the carburetor and the check valves in the plate under the bulb (known as the primer base assembly) push any air and old fuel inside the carb back into the fuel tank. On your model, the line inside the tank with the fuel filter on it will come out and go to the carburetor body BELOW the base assembly. The other line coming out of the tank (fuel return line) will go TO the nipple on the base assembly. The lines should be nice and soft and so should the bulb. They all have to be replaced periodically as alcohol, heat and age deteriorate them. Please post back if needed.

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.

My Poulan Pro weed trimmer SM132 does not run. I replaced the primer bulb and spark plug and it ran fine for 10 minutes. Now it will only start with the choke on and dies immediately. It will not start...


The primer does require two lines attached as it is a Walbro style primer. All four SM132 models uses the WT628 Carb. Since the trimmer ran 10 minutes then you have got all the lines connected right. Mostly you got trash in your carb or it simply needs rebuilding as the diaphragm may have pin hole in it or the check valves are worn out. Depending on the age and use of your unit you may also have a sticking piston ring.
