Stef's Cylindrical Dry Sump Oil Tank Assemblies

These revolutionary track tested designs incorporate a 360° perforated 4″ diameter integral vertical center baffle that forms a positive oil/air separation chamber against the outer tank wall. By contrast, traditional horizontally baffled or vaned tanks, which permit aerated oil to continue to swirl at higher r.p.m. levels is where STEF’S design first displays its superiority. This well proven concept promotes immediate downward oil flow and premeditate deaeration of return oil without scavenge line flow restrictions. Related design advantages employ an integral top vented breather tank, allowing only crankcase pressure to vent the breather as it’s virtually impossible for oil to reach the top center reservoir tank positioned breather tube. These tanks utilize a 4″ self-locking cap and internal accessibility thus allowing thorough cleaning without removing lids, baffles, O-rings, and/or clamps.
