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 DW300 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.
