    Took delivery of my 67 Charger yesterday. First task is to rework the fuel supply starting with the gas tank. The last time I did this on a car a radiator shop charged me about $15 less than a new tank.

    From looking at the underneath of the car it really looks decent for its age. When I drop the tank, if it still looks good and doesn't have a ton of loose chunks inside, is getting it boiled a good way to go? I would like to keep as many original parts on the car as possible. Is a radiator shop the way to go?

    I used these guys, but there isn't one near you. A radiator shop would be your best bet, you might even want to go around town and start asking a bunch of different shops what they'd recommend. Good Luck

    You answered your own question. It will most times cost more to refurbish than replace.

      66-67 B body tanks are usually less than $150. Replacing it is the way to go IMO.

        I would agree that replacing tank is probably the best way to go. Probably want to replace tank, sender unit and fuel line as well as hanger strap for the tank. If you have a big block, consider replacing fuel pump and fuel pump push rod as well. Chances are push rod is worn and shorter than it should be.

        Repairing and boilout is for a car that doesn't have a new tank available. If a new tank is available,it is by far a better choice. For my 33, or my 49 business coupe, salvage is the only option, for your charger , new is a no brainer imo.

          Spectra tanks are excellent. I also got new hoses and correct clamps.

            You likely will need the filler hoses and be aware that the lock ring on your factory sending unit is better than the reproduction so keep and reuse it.
            But as far as the fuel pump pushrod, I would measure it first not just replace it.
            I'm still running my original pushrod it has about 115, 000 miles on it.

              Great feedback. I get discount codes from the Rock, so a Spectrum sounds like the ticket. There is a decent (not original) 318 in it now but long term I will be swapping it out.

                    Same here. I'll gladly pay more for anything not made in China.

                      Just did this. Wanted to keep my original tank, but in the long run it’s better to buy a new one. I also found my sending unit was bad, I’m changing all of the hoses and lines, even tho they look ok. I reused my straps and painted them to match, and reused my locking ring, which I also painted.

                        IF I had to do it again I'd go with new if available. What a PITA!

                        The inside was pretty clean...

                        Outside it was another story...

                        I think the only thing I didn't try on it was that Goo Be Gone stuff.

                        Came out fairly nice....

                        That seal sucked. Allegedly for the application ('69 Barracuda), the fill tube would not go in it. The DMT seal worked great.

                          Look at Dixie Restorations is in your neck of the woods. IMOP, I'd just put a new tank in and be done with that part
