Increase your engine's performance with a Rotary Fuel Pump. You can run it with leaded or unleaded gasoline. Hot fuel boosters won't faze it. It's a rotary so it runs quiet and smooth without fuel surge. An internal pressure regulator supplies a constant 3 1/2 lbs. of uninterrupted fuel pressure at up to 30 gallons per hour. Each Rotary pump is supplied with a complete mounting kit and instructions. The new Rotary Fuel Pump is the right performance choice when moving up to a set of Superformance Dellortos or Webers.
