Questions & Answers

does the line from the primer pump stick in the larger hole on the gas tank or is there another way to attach this line? I know that the smaller hole is for the line going to the filter.
Don for model number pp338pt
Hello Don, Thank you for the question. The primer pump line would go tot he larger hole. Hope this helps, good luck with this repair!

Tools Used:

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

The fuel system disintegrates from the ethanol in gasoline, so I ordered the necessary parts; fuel filter and fuel line, purge line (different size), and a primer bulb, if one is needed.. If the primer bulb is tore, cracked, or makes a whistling sound, replace it first. Get a diagram online if your fuel lines are in pieces, but if they are intact, remove the fuel line from the back of the primer assembly, slowly pull the fuel filter and fuel line out through the fuel fill port. Cut your new fuel line's end at a diagonal, so that you can insert it through the hole in the gas tank. Slowly push enough through until you can grab it from the fuel fill port. Cut off this diagonal piece so that the end is once again square, and install your new fuel filter. Pull the fuel line back enough so the fuel filter is at an appropriate pickup point, I.e., close to the bottom of the tank while running. Cut the fuel line so that it just connects with the primer assembly. Remove the purge line from the primer assembly and use it to cut a new purge line slightly longer, with a diagonal cut on one end. Feed the diagonal end through the tank wall, and connect the other end to the primer assembly. I was able to do my 2 machines from one fuel line and purge line kit.

All of the fuel lines was broken due to me leaving fuel in the tank of the winter months.
I removed the plastic covers on the top and side of the chain saw to replace the fuel lines to the carburetor and primer bulb. I also removed the fuel cap and drained the fuel from the tank to connect the fuel line in the tank and replace the assy-pick-up and fuel line fitting.
