Tank incorporates a 360° perforated 4'' diameter vertical center baffle that forms a very effective oil/air separation chamber against the outer wall, allowing aerated oil to continue to swirl at higher RPM. Includes encapsulated element type oil heater, two elastomer lined through-bolt clamp mounts, two -12AN inlets and two -12AN outlets. A 4'' self-locking cap and internal accessibility allows thorough cleaning without removing lids, baffles, O-rings, or clamps.
