If you have ever lost engine power due to dirty fuel you would really appreciate this dual Racor setup. Vacuum gauge lets you see how dirty each filter is. You can select either filter or both.
Filters are mounted aft of the engine. Access is pretty good from the angled panel directly above it.
In addition there is an electric pump shown in the second picture which can be used to polish the fuel or bleed the system. Note the split cushion. This makes access to the shaft seal area easy.
