Using your XP 600 CP3 Fuel Pump is straightforward. First, make sure your vehicle is a Cummins or Duramax race vehicle as this pump is designed for them. You'll need to have a 290 GPH lift pump installed, as the XP 600 CP3 Pump requires it to work properly. This pump is only for race applications, so don't use it in regular daily - driven vehicles. When it comes to maintenance, check the pump regularly for any signs of wear and tear. The internals are hardened and DLC coated, which gives them good durability, but still, a quick inspection can save you from potential problems. Keep an eye on the flow and performance, and if you notice any drop, it might be time to have a professional take a look. With proper use and maintenance, your XP 600 CP3 Pump will serve you well in your racing endeavors.
