The purpose of a diaphragm in a vane type fuel pump is to

  1. Filter the fuel

  2. Pump fuel more efficiently

  3. Compensate fuel pressures to altitude changes

  4. Prevent fuel leaks

The correct answer is: Compensate fuel pressures to altitude changes

A diaphragm in a vane type fuel pump serves the purpose of compensating fuel pressures to altitude changes. This is essential to ensure that the fuel pump can maintain a consistent flow of fuel to the engine despite variations in altitude during flight. This feature allows the engine to receive the correct fuel-to-air mixture at all times, optimizing performance and efficiency. The other options are not correct because a diaphragm in a vane type fuel pump is not specifically designed to filter the fuel, pump the fuel more efficiently, or prevent fuel leaks, as those functions are usually performed by other components in the fuel system.
