    I’ve looked, and no one seems to make a replacement gas tank for this car.

    I’ve also looked in this forum and am unable to locate a thread pertaining to this issue for this car. Possible I overlooked it. Just a few threads stating whT I’ve already learned.

    Does anyone know of a suitable replacement gas tank for my lil econocruiser?

    Thanks in advance,

    The tank in the video looks more like what I’ve seen while under the car.

    The pic in the ebay link, not even close.

    If the tank is not a complete basket case you can have it sealed using Red Kote. I had a local radiator shop do it for me -- worked well

    Thanks for the heads up. Not sure exact condition of tank yet. Just trying to stay ahead of the game in case I need one. Going to be replacing sending unit this spring. So I’ll know more then.

    Clearly the link is wrong for your car. Totally different shape.

    Out of options down here in Australia, I have purchased an aftermarket ''fits 68 Impala'' gas tank to fit my 68 Wildcat, which I bought without a gas tank - it was converted to LPG (''propane") 25 years ago and I am returning it to gasoline power. I know the capacity is slightly different, but I am certain it will work. Very similar shape. Experience in the custom bike world tells me anything can be made to fit with willpower....

    Have a look at 70 Impala fitments?

    Funny you mention that. I’ve been looking at gas tanks for other makes and models as well. Gotta be something out that’s close enough.

    I’m with you, while not a custom bike builder. I’ve designed and put together a few things myself over the years. Felt I could get something in there despite it never being designed to there!

    Going to look at other tanks for other cars with the big ol Impalas in mind. Always did like the big Chevrolets from the ‘60s and early ‘70s.

    The Red Kote coated tank has the benefit of being rust resistant for years to come. Some of these “costed” new tanks don’t seem that well made….

    I’ve seen that ‘71 Electra tank a few times and felt it was probably going to be the closest fit. I think you’re right about the filler neck as well.

    Not at all opposed to the idea of going the route of using the Red Kote either.

    At the moment, just trying to plan ahead in my mind and bank account what I may need to do, if anything, once I drop the tank to replace sending unit. As well as inspect inside the tank.

    And I am worried a bit about the quality of the steel, thickness of the steel etc of the new tanks. Some, if based on price and comments by the manufacturer, appear to be pretty stout. While others, not so sure.

    The ‘71 tank we’ve discussed previously, seems pretty decent. In fact, really looks pretty darn close down to the location and number of vent or return pipes.

    My tank, from a still installed perspective is right solid on the bottom. It’s the top I can’t get to for now. As I said, just trying to get an idea, game plan before I drop the thing!

    Thanks everyone for the info, very much appreciated.
