Old Primer Bulb was cracked and would not pump fuel into the carb
- Removed top cover (to access carb area and allow side panel removal)

- 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

Remove from package and insert the plastic lanyard into the tank. Screw in place. New cap was a lot easier to tighten and sealed perfectly.

Saw would run and then stop. Would not allow air into the tank, but loosening the cap and it would run again for a short time
There is a vent in the fuel cap assembly that was plugged after being exposed to the fuel mixture. The new cap assembly allowed are to flow into the tank as gas mixture was drawn out. Replacement of the cap is easy and self explanatory.

The fuel line had deteriorated and had to be replaced
Remove the cover on the chainsaw to access the fuel line area.
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.

    Quick Replacement
    I didn't realize how bad my old fuel cap had gotten. Apparently it had swelled making it difficult to turn. On top of that, the vent had started leaking fuel. Fifteen seconds and it's ready to use.
