Fuel Safe recommends checking the fuel filter element for foam bits after running a new fuel cell.  At first I planned to remove the fuel filter canister from the car and then change the filter but further examination proved that would be a major PITA.  Fortunately SoS mounted the filter in a location where I could access it from under the car.  Next blocker was how to unscrew the fuel line coming from the fuel cell without twisting the line too much.  Tony C. told me to unscrew the blue part from the filter.  I did that while holding the red part still and got the line off.  Of course fuel started dripping all over but that's what drain pans are for.

The old filter was only moderately dirty and I didn't see any foam.  Maybe there's an in-tank filter that's preventing it from getting to this one?  Regardless, I replaced the old filter with a new one and then placed the old (and now clean) filter in the trailer as a spare.  Part number for filter element in pic below: PE 7500-6IL - http://www.product-engr.com/fuel_filters.htm

While I was underneath the car I also snipped off the old fuel tank wiring harness since it's connected to nothing.  There were 7 wires and 3 connectors in that bundle.  Saving weight - a few ounces at a time!
