ABSTRACT:
An end cap assembly for an in-tank fuel pump is configured to close an open end of a pump housing and includes an end cap body and a companion clip. On the bottom side of the end cap body facing the pump housing is a pair of motor brush wells for holding a pair of DC motor brushes. A pair of blind bores are provided to receive corresponding RFI suppression circuits. A pair of pockets are located in between the wells and the bores to allow flexible shunt wires to connect the RFI suppression circuits with the brushes. The clip is adapted for insertion into the bottom of the end cap body wherein a pair of axially-extending legs are guided into and seal the pockets. The captured shunt wires are electrically isolated in the closed pockets and contact with fuel is minimized.
