Fule filter change
1. Unplugged the WIF electricle connection

3. poured contents from filted into a glass jar as i will use the old dirty fuel for cleaning renches and sockets and such.
4. removed the WIF sensor from teh old filter and removed the larger (round) o ring from teh sensor as well and installed the new one on teh sensor.
