Purge Bulb 12318139130

Remove air cleaner and cover and slide small fuel feed line from purge bulb off metal tube of carburetor. Use a small screwdriver to gently pry the purge bulb feed from the bulb base. Pop the base up through the case with the screwdriver. Remove the small fuel feed from the old bulb and place it on the new bulb. Push the bulb down through the case until seated. Put the larger purge bulb feed on the new bulb and put the small fuel feed on the metal tube from the carburetor. Replace the air cleaner and cover. Pump purge bulb a few times and start engine.

2. Disconnected fuel lines
3. Removed broken purge bulb

The install was easy really, you can see what needed to be done at a glance.
Just be observant in getting all the fuel lines routed correctly.

With the help of the you tube video, took the old bulb out. Undid the gas lines watching which line went where. Pressed the new bulb in and re-hooked up the gas lines. I did find the you tube video to be very helpful!

Removed bulb and replaced unit.

I remove the air filter to get access to the carburetor and then I removed the fuel bulb put the new one on
