  • After you get it clean .....

    I am getting ready to replace a leaking gas tank in my Tudor, I have a very good one coming from Berts, but ..... I'm not totally sure what I should do now.

    I have read Brent's thread over on the old barn regarding getting a tank clean, by cutting apart and then re-welding. But what do you do AFTER you get it clean? What do you do to keep it from turning back into a rusty tank?

    My tanks are clean and all I do is use good gas without corn crap, and I use Marvel Mystery Oil 4 ounces per tank of gas.
    I also use the filter in the tank valve.

      One thing I did to avoid cutting it open is to remove the fuel tank fitting (on my 29 its the shutoff valve) drill the fitting on the tank side to fit a 1" piece of steel tubing,basically a riser off the bottom of the tank about 1 inch tall.This way if you don't get the tank perfectly clean,or you don't want to cut it you have a clear supply of fuel to draw from without any tank sediment.

        Many years ago, I read an article in the Restorer about a guy who took a freshly cleaned tank; put some liquid cleaner (don't remember what,) and added small ball bearings in the tank; sealed it up and rotated it a few times a day to remove the bigger hunks.
        Good enough.. Isn't.

          One of the guys in our club rigged up a rotisserie sort of thing with a cement mixer, then put ice in the tank and rotated it till the ice melted. Did that several times until the melted ice came out clean. Hasn't had a problem with it since then.

            Carl, was that cubed ice or whatever you found that wasn't yellow by the side of the garage?

            It's also a technique used in cleaning the septic tank on RV trailers.

          Gas tank restoration - suggested welding service?
          by Pklarkin
          Hi all,

          The restoration of my '29 continues, and I've turned to the gas tank. It appears to have a pretty serious leak at the top of the tank where the tank meets the fire wall segment. I'm not a welder... can anyone recommend a shop that i can ship the tank to, or to a DIY fix that doesn't require welding? Thanks for your suggestions.

          Gas Tank Rust Removal
          by CSPIDY
          Finally got around to addressing the rust in the gas tank of my 28 Tudor.
          the plan is to remove it, fill it with 10 gallons of Evaporust, clean with Por-15 cleaner degreaser, then prep with the Por-15 metal prep, followed with Por-15 paint coating.
          what are your thoughts? I have heard good reports on the Por-15 paint but have some reservations using an internal coating.
          any advise...

          YARGTT ( Yet Another Rusty Gas Tank Thread )
          by cpf240
          I've been following the various threads here on how members have been dealing with rusty fuel tanks. While I'd love to pull the tank and ship it off to Brent, that will have to wait.
          The Rust911 concentrate should arrive today. After a PM session over FB ( Facebook, not the ) with the Rust911 people, I'll be picking up 10 gallons of distilled water to use in the process.

          Hugh brought me his coupe yesterday with several issues . A no start condition and a leaking gas tank. According to Hugh his previous mechanic has swapped out the tank with a cleaned and sealed tank. I began by draining the tank which was full of bad gas afterwards I took a peak inside and found a white powdery residue covering the inside of the tank. No appearance of any type of coating. Their looks...

          Rinsing Out Fuel Tank

          I am sure this topic has been beaten to death, along with which brand of tires and oil....

          But has anyone done a simple "rinse" or flushing of the fuel tank before with minimal chemicals? My new car was stored for 20 years before my purchase. I do believe the tank was dry when it was stored as there was nothing in it when I took the cap off. It looked alright in there. ...

          by Beauford
          So when I received a gas tank I purchased I really didn't give it a good once over since the deal was done and guy said it had no dents and was a really nice tank. Got it back from sand blaster....what a waste of money. Huge whammy in the top corner. Nasty welds on upper corners of dash. Looks like fuel valve was snapped or cut off so there is a mess there....nobody will work on a tank correct due...

          Gas Tank Screen Restriction During Refueling
          by Fordfan29
          After years of driving my 29 without the factory screen in the gas tank filler neck, I finally installed one. Now when I refuel, getting that last couple of gallons in the tank is tedious. There is no way to slowly fill the tank with most automatic shutoff nozzles. The factory screen does not let the fuel flow through it fast enough. Has anyone cut the bottom out of the screen & does this...
