How do I replace fuel line on Jonsered 2054 chainsaw

Take top cover off(3 screws). Take off the 2 nuts holding the carb on. Pull carb part way out to access the hoses. Remove the 3 old hoses after making a diagram of where they connect. Buy new hoses. Cut one end of the small hose on a bevel, pierce both sides 1/8 th inch from the end with a needle. Thread a thin wire through both holes. Thread both wire ends into the gas tank. Use a hemostat or long needle nose plyers to pull the wires and then hose down into the tank. Attach the weighted fuel filter. The other end of this smaller diameter fuel line goes on the upper nipple on the carb. Take the side cover off (4 screws) to access the primer bulb. Take 2 screws out to remove the bulb which has 2 nipples. The longer nipple connects to the larger diameter hose which goes to the fuel tank. The larger diameter tube has a coupler on the end which is inside the gas tank. It took me an hour to change all 3 hoses.

Try your friendly neighborhood chainsaw seller/mechanic. Take a piece of the old hose with you.

Routing runs from fuel tank to carburetor, (if equipped) through carburetor to primer bulb, bulb returns excess to fuel tank.

The line at the rear of the fuel tank with the fuel filter is the main feed line to the carburetor and connects to the upper nipple. The lower nipple on the carburetor goes to one of the primer ports, and the other primer port goes back to the tank, which has no filter on the tank end. On the primer port, it is cut and try--remove the tank return connection and leave loose. Place the main fuel line on to one of the primer ports and try to pump fuel into it with several pumps.Make sure the filter in the tank is not plugged. If nothing, shift the line to the other port of the primer and try pumping again. When successful, remove the main fuel line and return it to the upper carburetor port. Run a new line from the lower carburetor port to the active primer port and try to pump fuel again. If it won't pump fuel, reverse the two connections at the carburetor and try to pump again. If still nothing, there is trouble within the carburetor which should be cleaned with spray carburetor cleaner and maybe re-kitted. When you can finally pump fuel through the carburetor, then attach the tank return line to the open port on the primer bulb. Hope fully, the engine should run at this point. Hope this helps!

No drawings or pix, but will try for description--the line from the tank that has the fuel filter is the main fuel source which goes to the upper connection on the carburetor. The lower carburetor connection goes to the intake side of the primer bulb, and the outlet side of the primer goes back into the tank, which has no filter inside the tank. The main problem is determining the correct primer port to connect back to the carburetor. When everything is connected, try priming the carburetor. If fuel fills the bulb, you have everything connected correctly. If nothing happens, try switching the two primer port connections and try to pump fuel again. If still nothing, hook the main supply line from the carburetor over to one of the primer ports and try for fuel again--if still nothing, switch the main supply line to the other primer port and pump again. If still nothing, check for a plugged fuel filter in the tank. If the filter was plugged, then go through the previous procedure again. Make sure to replace the fuel lines with original rubber lines, not plastic. Hope this helps!
