- Removed side cover where primer bulb is located
- Remove old snap in primer bulb (without disconnecting fuel lines)
- Cut and replace the 2 fuel lines one at a time (mine were hard and brittle from old fuel)
- The new bulb has 2 fuel ports, one is longer than the other which matched the old bulb.
- Installation instructions said to double check the direction of the fuel flow (the bulb sucks fuel through the carb, so the inlet side is connected to the carb and the outlet side goes back to the fuel tank).
- Snap the new bulb into place on the side panel
- Attach the side panel
- Attach the top panel
Refurbished model came with defective gas cap(no gasket/seal)

Remove the air filter to access the area.
Cleaned out the tank since there were pieces of fuel line floating around in the tank.
Had to fish the fuel line through the opening at the top of the tank and use long nose, bent tip needle nose pliers to pull it through. Had to cut the fuel line at an angle to make it go through the small opening in the tank.
After pulling the fuel line through the tank and inserting the fuel filter I had to pull the fuel line back in and then cut it to length and insert the other end into the fuel line tube outside the tank.
Install the covers back and the chain saw was operational after pulling the fuel line through the tank and inserting the fuel filter I had to pull the fuel line back in and then cut it to length and insert the other end into the fuel line tube outside the tank.
Installed all the covers back and the chain saw was operational.
Old and wore out
