- Unscrew the bowl and bowl header from the filter element.
- Turn the quick change ring of the filter element left until loose.
- Grasp the filter element and pull straight down until dislodged from the filter base. Note the six embossments for alignment.
- Fill the new element with fuel, making sure the grommet is lubricated. Align and install by pushing the element into place. Do not force.
