2.25in Fender Filler Kit

The JAZ 2.25in Fender Filler Kit is a remote fuel filler assembly designed for custom fuel system installations where traditional in-tank or door-mounted fuel doors are not practical or desired. This complete kit provides flush-mount, remote-mount capability with a vented twist-lock fuel cap, allowing builders to relocate the fuel filler opening to custom locations on the vehicle body—typically the rear quarter panel or custom-fabricated fender area—while maintaining a clean, integrated appearance.

The kit includes a 2.25-inch hose connection point that serves as the interface between the fuel cap assembly and the vehicle's fuel tank or feed line. Construction is steel with zinc-oxide plating, providing corrosion resistance suitable for long-term underhood or exterior exposure. The vented twist-lock cap design allows pressure equalization during fueling and emptying, preventing vapor lock or fuel surge issues common with sealed remote filler systems. All necessary hardware is included for installation, simplifying the integration process into custom fuel system layouts.

This remote fuel filler kit is ideal for custom vehicle builders, hot rod and classic car restorers, and performance enthusiasts executing non-standard fuel system configurations. It solves the challenge of fuel access in vehicles where the stock fuel door location conflicts with custom bodywork, wider fenders, or altered frame geometry. The flush-mount design eliminates the need for a protruding door mechanism and allows seamless integration into custom body panels, making it a popular choice for vehicles undergoing extensive fabrication work.
