Default Fuel tank help.

Is it possible to drop the fuel tank or do you have to take the body off the car? Also if you can drop it where is a good diagram?
Thanks!

Remove the spare tire carrier- all of it. There are 2 1-1/4 wide straps that run over the top of the tank and bolt into the rearmost crossmember- soak those bolts with your favorite penetrating oil. The tank sets on a crossmember that bolts in with 2 bolts on each side- soak those too. Take all those bolts out after you disconnect the wiring to the tank sender and the hoses. Tank comes out. Make sure it's empty- gas is heavy and the tank is not real light either.

Thank you! Maybe a second jack would help this process? Also im dropping it to replace all the rubber lines because they are cracked. Hopefully that will fix the starting problem. Does the car have to have a vacuum in the fuel system?

I just replaced the tank on my 68 L36. My biggest problem was the muffler hanger bolts that were (probably) installed by a muffler shop's air tools. The rest was easy. You just might find a sticker...

Where does the metal line that runs from car back turn into a rubber line to go to the tank? It's a 1978 Car.
