CJ Classics Premium Stainless Steel 22 Gallon Fuel Tank Conversion Kit for 1965-1966 Mustangs.

This Premium Stainless Steel 22-Gallon Fuel Tank Conversion Kit from CJ Classics comes with everything you need to upgrade from the 16-gallon fuel tank in your 1965 or 1966 Mustang to the larger 22-gallon fuel tank that is used in 1970 Mustangs. With a Premium Stainless Steel 22-Gallon Fuel Tank Conversion Kit, your Mustang will benefit from six extra gallons of fuel, a 40 percent capacity increase compared to the factory's 16-gallon fuel tank. Fewer stops at the gas station means longer road trips in your 1965 or 1966 Mustang!

If you are running a 4-barrel carburetor or any other type of performance modifications, looking for increased fuel range and security, the Premium Stainless Steel 22-Gallon Fuel Tank Conversion will increase your capacity using original dimensions, measuring 32-5/8" x 24-1/2" x 9-3/4", with the correct 22-gallon capacity. A drain plug is included for easy drainage. 

Features and Benefits:
- Increased Fuel Range
- 40% More Capacity than Factory
- 22-Gallon Fuel Tank
- Stainless Steel Construction
- Accurate Fuel Level Gauging

- 22-Gallon Stainless Steel Fuel Tank
- Fuel Tank Sending Unit

This conversion kit comes with a superior Fuel Tank Sending Unit that is specific for the 22-gallon fuel tank allowing for accurate fuel level gauge operation. The Fuel Tank Sending Unit features a 3/8" outlet tube and includes a plastic float, O-ring gasket, resistor, mounting plate and filter.

Your 1965 or 1966 Mustang's original filler neck will no longer work with the new 22-gallon tank, which is why the conversion kit includes a custom Fuel Filler Pipe, designed to be a direct bolt-on replacement that lines up perfectly with the neck on the 1970 Mustang's 22-gallon fuel tank. The brand new, high-quality Fuel Filler Pipe is made of thicker steel and is crafted with the correct notch for the gas cap seal to let air in and is designed so that the gas cap fits tight. 

Please Note: Molded trunk mats will no longer fit properly with a 22-Gallon Fuel Tank.
