67 barracuda gas tank removal

I have never needed to remove the filler tube. I walk the tank onto the filler tube first then set it against the floor pan. I have done this alone with one functional arm. The parts listed are correct. I would also replace the filler tube grommet where it goes into the tank.
Detroit Muscle Technologies "DMT" is one of our sponsor vendors and Jim and his wife Loretta are great to deal with. You can call him for the grommet or use the link below.

These cars are notorious for bad fuel gauges. If the oil and temp gauges still work then you're probably in luck as they are fed from the fuel gauges internal voltage limiter.

The 67 service manual has a 30-ish page supplement for barracuda. The individual pages for barracuda can be viewed/downloaded here.
