ABSTRACT:
A filter head having a pump housing, a flow passage network, and a mounting bracket is adaptable to engage a replaceable filter cartridge. An electric pump is positioned within the pump housing. A Seal/isolator disposed between the pump housing and electric pump protects the electric pump from vibrations. After changing the filter cartridge, typically an air pocket forms creating a danger for a fuel injector or fuel injector pump. By using an electronic controller, an operator may remotely operate the electric pump to prime the filter cartridge. Also, the electronic controller may selectively determine whether the fluid flowing from the filter cartridge passes through the electric pump or instead passes directly into an outlet.
