- Single-hole Installation: Unlike other sump kits, the SK5501 requires just one drilled hole in your fuel tank for a clean and streamlined installation. No need to drop the tank!
- Unrestricted Fuel Flow: The sump places the ½” NPT suction port at the absolute lowest point in the tank, ensuring your lift pump gets a consistent flow of fuel, even when your tank is running low.
- Say Goodbye to Quarter-Tank Issues: The extra-large, 6061 billet aluminum bowl acts as a reservoir, keeping your engine fed with fuel during heavy braking, acceleration, or when your tank is close to empty.
- Seamless FASS System Integration: The included ½” NPT return port allows for easy connection of the FASS return line directly to the sump, simplifying the installation process.
