Typical Example

The 172-4375 Mounting Gp (1) can be used to mount the 172-4388 Fuel Transfer Pump As and the 172-4389 Fuel Transfer Pump As (2) away from the engine. As needed, use the appropriate hardware and the hose assemblies. The pump life will be improved if the pump can be mounted away from the engine. This will reduce vibration which is the main cause of shortened pump life.
