Gas Tank Leaking - Repair or Replace
1 Attachment(s)
Just when we we ready to fire the engine, we put gas in the tank and discovered what looks like a serious leak. Bottom front above the crossmember that holds up the tank.
Questions: 1. Is the tank easy enough to remove? (Secrets?) 2. Repair or replace the tank? (Seam might be fixable.) 3. We see Long Island has new ones for under $300...seems pretty reasonable. Any experience? |
Replace without a second thought. Shop around, I got mine at Rock Auto.

Second on replacing. Very cheap if you think about it.

Replace, no doubt. If it's leaking at a spot now, it's almost a lead pipe cinch there are other places "almost" rusted through as well that will potentially be leakers in the near future.
Gonna be hard to beat Rock Auto's prices on a new tank, unless you opt for an original reproduction with the proper identifying stamps/markings. :thumbs: |
replace, they are inexpensive

Larry:
Buy a new reproduction tank with the logo from LICS or Quanta (the source). Then separately purchase a GM o-ring and a GM retaining ring for the gas sending unit. Many of the o-ring and retainer reproductions do not fit correctly, and can result in a fuel leak. A special (low cost) tool is available from LICS to remove the sender. You can also do without if you choose. A small brass drift works well. The archives are full of information regarding doing this replacement and the things to watch out for......but it is pretty straightforward. I did my 1967 convertible tank by myself with no additional help. However, having a second person is a benefit. Larry |

We looked into the tank from above berfore adding gasoline and it sure looked like new, thought it was galavanized. |
Originals were TERNE plated steel. This is a tin/lead alloy......it is not galvanized (zinc plated).
Not certain if the reproductions today still do the TERNE plating or use galvanized due to lead hazards. Larry |

Larry Powershift,
You answered the question on "Ni-terne" plated steel; THANK YOU! |
Quanta sells the reproduction direct from their website for $229, I don't know what they charge for shipping though?
I bought the one for my '62 from them at Carlisle, I think i paid $219 and of course no shipping. :cheers: Paul |
Larry,
I would suggest saving your original straps which are already bent exactly as needed for new install. New straps have to be bent to fit and usually are too short because you can't get the bends perfect. Take the old ones, clean them up and paint them. Also look at your old tank upon removal for bends around the lip ( you will see what I mean when you take it out and look at the new one.) You will want to bend the lip more where the straps go around. Use the old one to give you an idea how much. :thumbs: Don |

Questions: 1. Is the tank easy enough to remove? (Secrets?) From recent memory:
For reinstallation, it's the reverse of all of that, but: If you purchase a new tank be aware that you will need to bend the tank assembly flanges a little more than they are already bent, because they are not folded over enough when the new tank is made - the result is the tank straps will not go around the tank properly and the tank will not be centered if the flanges are not addressed.

Thanks Paul and Ron,
It looks like Quanta is the maker of these repro tanks $229 at Quanta and Paragon, $239 at Long Island. Plus $59 shipping.
