Question about Chainsaws
I am trying to replace the fuel line on a 1999 2175 type 2 Poulan chainsaw. The old lines have disentegrated and I need to find the line routing from the primer bulb. The info on the plate is
Family XPWES 0424CS:EM
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.

The fuel line from the tank filter goes to the carby and the other tank one goes to the "out" on the primer bulb. the other one on the bulb goes to the carby.
Now If the primer isnt marked there is a long and short nipple, and I cant rememer which is which...If you press the the prime rwith the hoses off you can find which one is sucking(in) and the one that blows (out).
The "in" on the caby (tank filter hose) is usualy the pipe that is in the aprox middle position, out (return, primer) is usualy ont outer position.....
the primer basicaly pulls air and fuel out of the carby and back in to the tank, not pushing it into the carby like most ppl think.
if it wont prime swap the hoses around on the carby and try....if that still dont work the caby diaphram might be US.

I also might add...the hose from the primer bulb to the tank is bigger than the hose from the primer bulb to the carb. No way can you put them on backwards. If this helps.

I had a hard time with the coupler on the end which is inside the gas tank. I ran a string in the opening and fished out throught the gas cap opening. Then I put through the coupler and tied a knot. That allow me to pull in position inside the tank. I threaded the string through the large tube an tried to push in the hole. After I finally got the tube in the hole I pulled the coupler into the tube inside the tank. I never could get the coupler back in the hole. Just got it to start.

An exploded parts list for a 4218 type 2 chainsaw follows (May not be your saw):
Poulan.com The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best. They are also beneficial with disassembly/reassembly. Fuel components and part numbers are listed but may be on different illustrations:
The dash number of your serial number is the type.
A very good general diagram of a 2-cycle fuel system can be found here:
