With the base removed the filter will come out with some wiggling.
This was actually the end that faced the gasket and we can see evidence of water infiltration. The previous pictures show the filter inserted for illustrative purposes only and it was upside down from the way it actually came out. Despite being down stream from a Racor primary fuel filter the pump still had some water in it. This was likely due to a failed 0-ring on the boats fuel fill.
Facet no longer uses metal/paper filters in these pumps, this one was 27 years old, and they are now just a simple 74 micron screen.
