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.

SOURCE: Poulan Trimmer PPB100 fuel lines

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.

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.

Replaced gas tank and primer bulb on my Poulan Leafblower FL1500 and it appears I'm not getting gas into the carb. Any ideas as to what my be the cause?


I assume the new tank came with new fuel lines and filter in it.
First be sure you have all the lines hooked up correctly. There should be a main line from the tank ( has the fuel line on the end of it in the tank) to the fuel pump side of the carb. Then there should be a line leaving the metering side of the carb to the primer bulb then from the primer bulb returning to the tank. When you press the primer bulb you should see it **** the fuel into the carb then from the carb into the primer bulb then back into the tank.
If the fuel lines are all hooked up correctly then you should rebuild the carb.

Poulan GHT-22 Hedge Trimmer The Primer Button Will Not Inflate


When changing the fuel lines did you get them back in the correct location? This would prevent the bulb from working. Also, if the bulb is old and brittle or leaking, would also cause hard start or leaks around the handle.

Either the fuel lines that were replaced are a poor fit in the tank ( wrong diameter pipe ) or the pipes have been connected incorrectly to the fuel primer bulb.
