Upgrade your classic Chevy or GMC truck with the Tuckers Complete Aluminum Gas Tank Kit, designed to relocate your fuel tank between the frame rails for a cleaner appearance, increased fuel capacity, and a modernized fuel system.

Why Relocate Your Classic Truck's Gas Tank?

Move Fuel Storage Away from the Cab

On trucks originally equipped with an in-cab fuel tank, relocating the tank between the frame rails moves fuel storage outside the passenger compartment.

A properly designed and installed relocation system can be a worthwhile improvement during a complete restoration or custom build. Overall safety depends on mounting, protection, venting, plumbing, and installation quality.

Increase Your Fuel Capacity

A replacement aluminum tank can offer additional fuel capacity compared with some original configurations, potentially allowing you to travel farther between fill-ups.

Actual capacity and the increase over the original tank depend on the specific tank and vehicle configuration.

Cleaner Interior and Exterior Appearance

Removing the original in-cab tank can create additional opportunities for interior customization, while the side-fill configuration provides a dedicated exterior filling location.

Convenient Complete Kit

Instead of sourcing the tank, filler components, sending unit, and fittings separately, this kit brings together the major parts needed for your conversion.

Fuel Sending Unit Compatibility

Selecting the correct sending unit resistance range is important for accurate fuel gauge operation.

Tuckers aluminum gas tank kits are configured with the following sending unit ranges:

This 1947–1953 kit includes a 0–30 ohm sending unit.

If your truck has aftermarket gauges or a modified electrical system, verify the required sending unit resistance before installation.

Side Fill vs. Top Fill Gas Tank Kits

Tuckers offers aluminum gas tank relocation kits in both side-fill and top-fill configurations for select 1947–1987 Chevrolet and GMC trucks.

Side Fill Gas Tank Kits

Side-fill kits use an exterior filler door and hose assembly to provide access to the fuel tank.

This configuration is a popular choice for truck owners who want convenient exterior fuel filling.

Top Fill Gas Tank Kits

Top-fill configurations use a Cool Cap assembly to provide access to the fuel tank from above.

The best option depends on your truck's bed configuration, desired appearance, and intended filler location.

This product includes the side-fill configuration.
