Default Installation of new AF Perf fuel pump

After nearly 1800 hours of operation of our RV8, the original Airflow Performance boost pump has become increasingly noisy. It has finally gotten loud enough to cause concern, so rather than waiting for failure I decided to change the pump. The new pump is the Air Flow Performance #2090255, sold by Van's as "EF Airflow Fuel Pump-1." The new pump has vastly simplified the installation, as the bypass is internal to the assembly, eliminating the return line to a "T" at the fuel selector valve. The installation eliminated seven fittings and about 18" of fuel line. A very nice assembly! The photos show how neat it is:

The photos of the fuel filter are a bit confusing. The line comes out the bottom of the fuel selector valve, and curves around to the back of the filter.
