22 Gallon Fuel Tank Conversion Kit for all 1965-1966 Mustangs.

This 22-Gallon Fuel Tank Conversion Kit 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 22 Gallon Fuel Tank Conversion Kit your Mustang will benefit from 6 extra gallons of fuel, which is almost 40% more compared to the factory 16-gallon fuel tank. Now you will be able to avoid those frequent stops at the gas station and finally be able to enjoy longer road trips in your 1965 or 1966 Mustang with peace of mind.

This 22-Gallon Fuel Tank Conversion Kit makes the switch to a larger fuel tank relatively painless and is a smart upgrade for anyone looking to increase fuel capacity. So, if you are running a 4-barrel carburetor or any other type of performance modifications, looking for increased fuel range and security, or just simply tired of filling up your tank so much, this 22-Gallon Fuel Tank Conversion Kit is perfect for your 1965 or 1966 Mustang!

Fuel Tank Conversion Kit Includes:
- 22-Gallon Fuel Tank
- Fuel Tank Sending Unit
- Custom Fuel Filler Pipe
- Fuel Tank Filler Hose
- Fuel Tank Mounting Hardware Kit
- Fuel Filler Pipe to Body Gasket
- Fuel Tank Filler Screws

The focal point of this conversion kit is of course the 22 Gallon Fuel Tank. This fuel tank is a direct replacement for all 1970 Mustangs, but will fit in any 1965 or 1966 Mustang using the factory mounting locations, without any modifications. The tank is made using original dimensions, measuring 32-5/8" x 24-1/2" x 9-3/4", with the correct 22-gallon capacity. It comes with a special coating that prevents rust and corrosion. A drain plug is included for easy drainage.

This conversion kit comes with a 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 stainless steel construction with a 3/8" outlet tube and uses a brass float. A retaining ring, o-ring gasket and filter are included.

Your 1965 or 1966 Mustang's original filler neck will no longer work with the new 22-gallon tank and must be replaced. That is why this 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 from thicker steel compared to the original filler pipe found in the 1965 and 1966 Mustangs. It features the correct notch for the gas cap seal to let air in and is designed so that the gas cap fits tight. This Fuel Filler Pipe is improved in every way possible over an original filler neck, but still looks like an NOS part.

Connecting the custom Fuel Filler Pipe to the new 22-Gallon Fuel Tank, is a durable, 4" long Fuel Tank Filler Hose that is made from flexible, hard rubber. Replacing this hose is always recommended when installing a new fuel tank.

The best part about this conversion kit is the fact that everything bolts up to the factory locations using original hardware. If you don't have original hardware to use, a Fuel Tank Mounting Hardware Kit is included, which comes with all the necessary mounting hardware required to drop in the new fuel tank and secure it.

Please Note: Molded trunk mats will no longer fit properly when a 22-Gallon Fuel Tank Conversion Kit is used because the larger fuel tank will eliminate the hole that the molded trunk mats fit into.
