Ford Mustang Scott Drake Enterprises Tank Armor 22 Gallon Fuel Tank

For installation of the 22-gallon tank in a '65-'68 Mustang, you will need to use that generation's fuel filler neck. However, because the 22-gallon tank is taller, you will have to cut approximately 11/2-inches off the neck at the tank.

We decided to add mounting holes to both the fuel tank and Tank Armor. Here, pilot holes are drilled first for accuracy, then a 5/16-inch hole. If you want to give yourself some wiggle room, drill 3/8-inch holes and use flat washers on your fasteners.

Our Tank Armor has been sprayed with corrosion-resistant Cold Galvanizing from Rust Oleum. Fit has been checked and we're ready to install hardware. We strongly suggest the use of 5/16-inch Grade 5 or Grade 8 bolts, lock nuts, and flat washers. The Tank Armor kit comes with 1/4-inch bolts with locknuts and flat washers. Don't use the factory-style sheetmetal screws.

Here's the installed 22-gallon tank with Tank Armor. Based on what we learned from this installation experience, install the fuel filler hose before the Tank Armor.

We've cut the '67-'68 fuel filler tube 11/4-inches to create a 1/2-inch gap between tube and neck. The neck has been bent ever so slightly toward the front of the car to align with the filler tube.

During this installation, we learned that there are some filler tube/hose clearance issues with Tank Armor and a larger-than-factory 22-gallon tank in a '65-'68 Mustang. Again, install the filler hose before Tank Armor or trim the Tank Armor before installation.

The filler hose clamps can be positioned any number of ways.....

....Here are two. Due to clearance issues with Tank Armor, we are limited to one way on the bottom clamp.

Completed installation looks like this. We have six more gallons of driving range and a safer installation.

Because today's automotive fuels are hard on fuel systems, we suggest using high-pressure fuel injection hose at the sender and where the two body lines join. You should also hard line your fuel system between the pump and carburetor. If you can't, use high-pressure fuel injection hose there along with quality worm gear clamps.

Pop-open gas caps were a clever idea for their time but are unsafe. With reproduction pop-open gas caps, you can opt for the spring-loaded cap or improve safety with a fit and twist, which is safer because it's less likely to pop open in a collision. The pop-open feature then becomes a fuel door.
