Abstract
A filter head including a lid extending along a central axis. The lid includes a filter bowl receptacle positioned coaxially about the central axis, a central receptacle positioned coaxially within the filter bowl receptacle, and an intermediate receptacle positioned coaxially between the central receptacle and the filter bowl receptacle. A conduit portion connects to the lid and extends along another axis that is normal to the central axis of the lid. The conduit portion includes a first pathway extending between the first end and the filter bowl receptacle, a second pathway extending between the first end and the central receptacle, a third pathway extending between the second end and the central receptacle, and a fourth pathway extending between the second end and the intermediate receptacle. Couplings allow the filter head to be pivoted about the central axis of the conduit portion.
