ABSTRACT:
A submerged pump manifold for a liquid fuel dispensing system. The pump manifold includes a chamber for housing a filter cartridge and a cover attached to the top of the chamber. An interlock device is removably attached to the cover such that the device must be removed upon removing the cover. The interlock device is attached to a plug-type connection on the pump manifold so that as the interlock device is rotated away from the cover, the plug-type connection is moved from its plugged-in position to its unplugged position, thereby electrically disabling the submerged pump while the cover is removed.
