The bilge pump on the M548A1 is located in the right front corner of the power plant
compartment. On the M548A3, the pump is located in the rear center of the engine
compartment. The screens and vent holes are maintained in the same way.
The pump has an inlet screen to keep the pump from swallowing junk that could jam or break
the pump. But if the screen gets blocked (with big leaves, paper, cardboard and other debris)
the pump cant suck any water.
Clear away any trash on the inlet screen. Keep the carrier bilge cleaned out.
The bilge pump has a vent hole that you need to keep clean. If the vent hole gets clogged, the
pump could become air locked.
Clean the vent hole by running a wire back and forth a few times.
