  • Overall Compact Size: 4 ¼” tall x 3” wide x 3 ¾” deep

  • Weighs: 19 oz

  • Base/Manifold: Red, Billet 6061-T6 aluminum base/manifold. Not a casting. Mounting holes: 7/16" - 2 inches center to center

  • Stainless steel filter adaptor

  • Flow: 300 gallons per hour (1,800 - 1,875 lbs per hour) 

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

  • Filter media surface: 183 sq in. FloMax™ enhanced water-stripping cellulose.

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

  • Burst: 250 psi (ideal for fuel injection or carburetor)

  • Ports: Multiple (2-In, 2-Out) ½” NPT (pipe thread) so that brass fittings can be used to splice into your existing fuel line and the ability to add accessories like fuel pressure gauges, etc.

  • Replacement FloMax™ spin-on type filter: (# RF300) for ease of changing. Nothing to service or clean out, eliminating the chance for fuel system contamination.


High flow & highly efficient filtration make the FloMax™ filter systems the most innovative and efficient fuel filter systems ever built. The RPM300 is very popular in the Jeep and small marine/pleasure boat markets. Price: $159.95
