Note: This product is suggested to be installed with a FASS Titanium Signature Series Systems. The larger suction tubes and Fuel Sump Bowl improve fuel delivery and work perfectly with a higher-volume fuel System.

Installing a FASS Fuel System has NEVER been easier! Their all-new Return Style Fuel Tank Sump Kit only requires a single hole to be drilled into the fuel tank, and includes a ½” NPT return port—allowing you to plumb the FASS return line right to the Fuel Tank Sump.

This Return Style Fuel Tank Sump Kit also places the ½” NPT suction port at the lowest point in the fuel tank, ensuring unrestricted fuel flow to the FASS System.

Last but not least, the extra-large bowl acts as a reservoir—creating a consistent supply of fuel to the FASS System when running close to empty, or under heavy braking and acceleration.
