Question about Craftsman 25cc Gas Line Trimmer

2 Answers

Replace fuel lines,craftsman weedwacker, 358.798520 . Fuel lines disintegrated in gas tank. Three parts left in tank, fuel filter and two small plastic hose connecting items.How are these parts related to each other and how are new fuel lines connected to them. One line is fuel supply from fuel tank to the carb and is slightly larger in diameter than the other one that goes to the primer bulb from the fuel tank. A diagram would be very helpful. Thanks, JS.

Fuel filter in tank with line going directly to the fuel pump side of the carburetor This is the end of the carb with a solid cover. . This line should have length in it inside the tank where it can flop around and stay on the bottom to collect fuel. The other line in the tank should have one of the little connectors on it and can be right up to where the hole in the tank is to hold it there.. This line should connect to purge/primer bulb on the longer outlet nipple. Another fuel line should run from the metering chamber side of the carb (the end with the hole in the cover) to the purge/primer bulb with the shorter outlet nipple.
The purge bulb "pulls" fresh fuel out of the tank via a vacuum created after depressing the bulb and the fresh fuel flows completely thru the carb and any air or old fuel ahead of it are drawn to the purge bulb which then "pushes" this mixture back to the fuel tank.

    I agree a video changing the fuel lines is extremely helpful for those of us that need a diagram for reference purposes.

Craftsman 21cc weedwacker, need fuel line diagram


This is an ongoing issue for users, and rightfully so. 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.

Weedwacker won't start


Is there an air lock in the line. Remove the lines and insert only one at a time and see if one will take fuel and the other none? Also, check carb float to make sure its not stuck open intaking fuel constantly flooding bowl

Fuel Lines - 25cc Craftman weedwacker


Your Craftsman Trimmer/weedwacker:

Best Poulan Engine Match (probably real manufacturer):
http://www.ordertree.com/modelinfo/PWE/BC2400-Gas-Trimmer-Type-6/75.BC2400-Gas-Trimmer-Type-6.1.59.1.html

My decisions are being driven by my experience with Poulan chainsaws. Small hose in tank (long enough to reach all corners), filter on bottom, connects to lowest connection on carburetor. Small hose on upper carburetor connection to small fitting on primer. Large hose from large connection on primer through largest tank hole, roughly mid tank long. nothing on bottom. I suggest you leave the 2 connections on the carburetor long enough they can be swapped (just in case) then try it. if no go swap them.

Typical fuel system and a suggestion or two:

This is how I would configure it if a chainsaw, doubtful they would do something completely different. In defense of Jerry, he knows how it should be done, clarity of instruction could use some help. Good Luck. HTH

Craftsman weedeater will not start


The most probable problem is no fuel delivery to the engine.

1. Check/replace the fuel in-tank filter, you should be able to easily blow through it once removed. The primer bulb will sink down and not return quickly if the filter is bad. Fuel will not return to the tank via the return line if the fuel filter doesn't allow fuel to be pulled in.

2. If fuel is returning to the fuel tank when the primer is pushed then your problem is inside the carb.

3. To verify this put a small quantity of gas in the lid of a water bottle (half full). And pour it into the carb throat. Replace the air filter to prevent a backfire from shooting flames out. Try to start the weedwacker. If it runs and then dies the problem is inside the carb.

4. If you are really good at working on things with small parts you can clean out the carb and replace all of the gaskets to solve the problem. If this isn't for you then you should take it to a lawn shop and have them clean the carb and replace the gaskets.

NOTE: Replacing the gaskets is very important because the gaskets get stiff and the fuel pump action of one of the gaskets is reduced or stopped.

Hope this helps, Karl

Craftsman weedwacker keeps dying


If the weedwacker runs OK on 1/2 choke or even better on full choke then most likely the cause is the carb gaskets are stiff and can no longer pump the fuel. Of course make sure the fuel lines are are the right ports (return and supply). While you have the carb apart clean all of the passages with carb cleaner.
