Tech tips
- Choose flow capacity around the complete fuel system and intended use; a GPH rating is not a guaranteed horsepower or fuel-economy gain.
- Use the exact kit's installation instructions for hose routing, electrical connections, priming, leak checks and operating-pressure verification.
- Confirm tank, pickup and filtration modifications before scheduling installation. The overview above does not replace the installation manual.
