Introducing one of the highest flowing in-tank pumps yet. Surpassing the competition 320LPH at a time.

  • Flows 320+ litres per hour
  • Ethanol compatible
  • 3-year no-fault warranty
  • Quiet and reliable turbine impeller

Kit Includes

  • 2"x2" sock
  • Electrical connector
  • 4" of fuel line
  • Miscellaneous hardware

Also included is the MAP fuel pump installation kit to make installation a breeze! Our CNC machined fuel pump housing designed to replace the factory fuel pump/filter assembly and includes all hardware for a bolt-on installation.

Important Note: We have found that these fuel pumps require a significant amount of amperage, depending on your application rewiring the fuel pump may be required for optimal performance. If your fuel pump is not working as advertised and/or you are experiencing a drop in fuel pressure please ensure rewiring the fuel pump is your first step in the troubleshooting process! See the below item to solve all of your wiring needs!

Optional Hardwire Installation Kit

Get the most out of your 9-301 or other high flow fuel pump by ensuring it is getting the voltage it needs. Old, compromised OE wiring can limit the voltage your fuel pump receives. Our hardwire kit includes everything you need to safely, easily, and reliably wire your pump directly to your battery, ensuring no matter how hard you push your pump, your wiring will be up to the task. We especially recommend this kit for use in cars over 10 years old, cars making over 400whp, and cars which were originally not designed for high horsepower.

Installation Instructions

Important Disclaimer for Evo X Owners: It has come to our attention that installing a high flow fuel pump in the Evo X may cause excessive fuel pressure in the return line. The issue appears to be caused by an intentional restriction in the fuel pump housing that is designed to scavenge fuel from the passenger side of the fuel tank. We have not yet heard of any issues from E85 users (which is most likely due to increased fuel requirements), however several pump gas users have experienced issues in which the fuel return line will detach from a joint or the fuel pump housing itself resulting in a fuel leak. The increased fuel pressure will also have an effect on your tune causing a rich condition. We are currently exploring a fuel pump housing modification with the hopes of rectifying these issues. In the meantime if you plan to run pump gas with a high flow fuel pump we strongly recommend installing a fuel pressure gauge to monitor conditions and ask that you proceed at your own risk.
