Claim:
1. A coalescing filter element comprising a) At least one particulate filtration layer; b) A coalescing layer promoting coalescing of water particles, wherein the coalescing layer is downstream of the at least one particulate filtration layer relative to the flow of fluid through the element; c) An annular coalescing space downstream of the coalescing layer; d) A sump in a lower portion of the filter element in fluid communication with the annular coalescing space; e) A hydrophobic layer downstream of the annular coalescing space, wherein fluid being cleaned by the element flows through the hydrophobic layer, wherein the filter element is an inside out flow design, and wherein the filter element includes a lower end cap and an intermediate end cap on opposite sides of the sump, wherein the filter element includes an upper end cap and wherein each of the particulate filtration layers and the coalescing layer extend between the upper end cap and the intermediate end cap, wherein the hydrophobic layer downstream of the annular coalescing space extends between the upper end cap and the lower end cap, and further including a spacing support tube between the annular coalescing space and the hydrophobic layer which is downstream of the annular coalescing space.
