This is an ongoing issue for users, and rightfully so .On your machine.. Small diameter line out of fuel tank (has filter in-tank on end) connects 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. Years ago on 2-stroke trimmers, primers were not even used,...you choked the carb with a slide lever and gravity let fuel enter the carb from above...a few pulls, a "pop"...slide it off of choke and away you went.
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 the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank.

    this sounds bakwards i thought the pump had a vent hole

    Under the cover with 4 screws and a vent hole is the metering diaphragm. When it flexes, it pushes down on the end of the metering lever and opens the needle valve allowing the fuel to come in from the other side of the carburetor. A chamber (cavity) there acts as a reservoir holding the fuel until it is needed in the idle circuit or the high speed circuit or both. The other side of the carburetor is where the fuel from the tank enters first. It is "pumped" thru a small inlet screen and tunnel to the needle valve area when the carb receives the "pulse" signal from a vacuum created by the engine turning over. The flaps in the pump diaghragm on this side of the carb help to "push" the fuel to the metering side. If you open a diaghragm carb up you will surely see it. There are teflon pumps and buna pumps and mylar pumps. Tan, black and clear are their respective colors. Some people do call the metering diaghragm the pump but it actually is not....it's the colored diaghragm on the other side of the carb that does any pumping action. The information I've given you is correct as I own the same machine and have worked on it. Please look at this Zama tech guide: http://www.zamacarb.com/pdfs/TechGuide_2...

SOURCE: repairing fuel line on craftsman 32cc weed trimmer.

Cut the end of the line at a sharp angle. Spray WD-40 on the line and fuel tank hole. Slowly screw the line in the tank far enough so you can connect the fuel filter if you are replacing that line. If not just push the line into the tank if you have a two line system. Remember on the fuel primer, the long tip has the line going to the tank, and the short tip has the fuel line going to the carb.

I need the fuel line routing diagram for a Craftsman Model No. 358.791510 Weedwacker 32cc/1.9 cu.in. 2-cycle


The fuel line in the tank connects to the nipple. It then goes into the small hole in the tank and then the fuel line from the carb connects to the nipple. This line is the line that is attached to the body of the carb, not near the plate.

Need to know the fuel line routing including the primer bulb.


The smaller diameter line (fuel supply) goes from the fuel tank (w/filter) to the carb body. Look carefully at the 2 nipples on the carb. You can tell one is slightly larger than the other. Another larger line (purge line) goes from carb body to the right nipple on the primer bulb. Another large line (return line) goes from the left nipple of the primer bulb into the fuel tank. completing the purge circuit. This info pertains to the Craftsman 32cc with Zama carb and may work on the 25cc model as well.

I have a 32cc crasftzman weed wacker need how to


This can be a little tricky, the filter is in the tank connected to the line. The line is pulled through a hole in the tank which seals only because the line is the correct outter diameter to seal the hole and not collapse the interior. Fuel line and filters are available at most places that carry outdoor power equipment parts but you must make sure the line is the exact size inner and outter as the original.
If the trimmer has a primer bulb the line goes from the tank to the bulb and then to the carburetor, a second line goes from the carburetor back to the tank, don't get them mixed up.
