  • Weighs: 24 oz

  • Base/Manifold: Billet 6061-T6 aluminum base/manifold, anodized Clear (popular in the Street Rod market). Not a casting. Mounting holes: 7/16 - 2 inches center to center.

  • Filtering: 4 Micron FloMax™ media (gasoline-methanol-ethanol compatible!)

  • Filter media surface: 183 sq in

  • Water Separation: Actually separates water to the “quiet” zone for water & heavy contaminates to settle. Not water blocking (which actually blocks the fuel).

  • Ports: -8 A/N (ORB). Multiple (2-In & 2-Out) for the ability to add accessories like fuel pressure gauges, etc. Also comes with two -8 to -6 reducers if needed.
