Using this lift pump is quite straightforward. First, follow the installation guide provided. Make sure to click on the installation link in the product description for detailed steps. If you're installing it on a cab and chassis, be aware that you might need to make some modifications. Once installed, the pump will start working to filter your diesel fuel, removing water, air, and debris. This protects your injectors and improves engine performance. For maintenance, keep an eye on the filter life expectancy. The filter should be replaced every 30,000 miles to ensure optimal filtration. Also, since the pump has a limited lifetime warranty for parts, if you encounter any issues with the parts, you can get them replaced. The Mass Flow Return (MFR) technology keeps your fuel clean, so there's no need to worry too much about fuel contamination. In cold weather, if you've opted for the electric heater ports, it can help with better starts. Enjoy the benefits of improved fuel mileage, smoother engine idle, and reduced emissions with this great product.
