The Titan Fuel Tanks 9900025 filler neck kit is built for use with Titan PN 8020017 and 4020217 after-axle tanks. It packages the fill-side components needed to complete the fuel filler setup, including a flat-flanged filler neck, fill hose, vent hose, clamps, and fuel cap.

This kit gives the installer matched hardware instead of forcing separate hose, cap, and clamp sourcing. The included 1-1/2 in x 18 in fill hose and 3/4 in x 19 in vent hose support the fuel-fill and vent routing needed for the compatible Titan after-axle tank setup.

The kit is intended for the listed Ford Super Duty applications and compatible Titan after-axle tanks. It includes a cap and black finish components, with no supplier warranty listed for this SKU.
