Fuel Polishing System

[Administrator]

I wish...

Someone could think of a way to add a fuel polishing system to an A4 installation.

Such a system would use a stand-alone Racor filter and a continuous duty fuel pump (also stand-alone) to recirculate filtered fuel back into the tank. A plus would be the capability to use the polishing system as a back-up to the engine's primary system. A timer would be nice, too.

Major technical challenge: How do you plumb the pickup and return at the fuel tank?

Fuel Polishing

The fuel return from the polishing system should be above the engine fuel pickup. The intake for the fuel polishing filter should be below the engine fuel pickup. Would not run continuously, only when engine is operating. Make sure you get a pump that will not burn out when run dry or install a cutoff switch when fuel is low.
