ABSTRACT:
A backup fuel pump (16) has a thermal fuse (40) positioned in a bearing. The fuse is adapted to melt at a predetermined temperature during dry running of the pump. Melting of the fuse causes a spring urged braking member (42) to screw into a shaft journal (26) and terminate operation of the pump.
