Replacing Your Classic Ford's Fuel Tank - Bird Feeder

Marks inspects both straps in the interest of safety and security. Both are plagued with corrosion but are serviceable. The application of something like POR-15 will markedly extend the life of these straps.

After lubricating the filler-neck O-ring seal with white grease, install it and check for security...

...This is what you can expect with any full-size Ford or Merc because all are similar to the Thunderbird. On the left is the fuel vent hose.

Marks gently slips the fuel filler neck in as shown. Check for solid sealing during this process. The neck should be snug. If it isn't, determine why, and consider the need for a new filler neck. A word to the wise-replace the fuel vent hose while you're at it, even though we didn't.

Secure the tank and tighten the straps...

...All that remains is the fuel filler neck and fuel hose.

The 31/48-inch high-pressure fuel hose is connected above the rear axle.

Our American Designers fuel tank looks sharp, functions well, and will keep Marks' Thunderbird off the flatbed for a long while.
