    Fuel Pump Breather

    After a recent flight, for the first time, the engine mounted fuel pump breather line started dripping fuel. Any idea why that might be? Thanks.

    Bad diaphram. Replace pump.

    It’s not a breather. It’s a dump line for fuel leaked past a bad pump diaphragm. It directs the fuel away to reduce fire risk.
