Used by Warren and Kurt Johnson, MagnaFuel ProStar 500 fuel pumps are built with computer-machined aluminum bodies. They feature custom-built motors and an exclusive vane/rotor design to provide cool, low-amperage operation without overheating. Compatible with gasoline and alcohol fuel, these pumps use an externally adjustable bypass to eliminate pump cavitation, stabilize fuel flow, and eliminate fuel starvation. They feed engines up to 2,000 HP.
Features
High performance when rated at flow vs. pressure External by-pass to eliminate pump cavitations Instantaneous compensation for sudden changes in fuel demand Consistent, reliable fuel supply for optimum carburetor performance Compatible with both alcohol and gasoline racing fuels Light weight Hand assembled to the highest quality standard Pump bodies computer machined out of high quality 6061 Aluminum Custom built low amperage motors – the best in the industry Compatible with 12- and 16-V electrical systems No metal to metal contact for reduced wear and greater reliability Blades self-compensating for wear Flow tested to ensure maximum performance All MagnaFuel pumps are rebuildable to “as-new” factory specifications
