Heavy rust, put in rocks and strap to the front of a cement mixer and run it.

Re: gas tank
Substitute ICE for the rocks. You will get the same results and you won't have to fish out all the rocks when you are done.

Re: gas tank
How does the 5 pounds of rock all get behind the baffles, ...and then when they do, how do you get all of them out? I cannot begin to tell you how many we have opened to find 5 lbs of trapped debris (nuts, bolts, rocks etc.)

Re: gas tank
Brent is spot on
Anything short of opening it up will be worse down the road. Get that tank painted and in the car and start getting a clogged fuel system and u will wish you did just what is described Heed the advice! |

Re: gas tank
Have I missed something? Is the OP all the information we get for this quiz????? Is the tank out of the car? Is there a large rust hole in the tank ? Is the rust a minor external stain track? Is the rust clogging the fuel system? Or are simply rust particles visible in a glass sediment bowl? You guys seem to have firm answers to the question before I've even got sufficient data to hazard an opinion!!!

Re: gas tank
Too wordy to read the whole thing, but I think I understand.
I'd still try the liquid rust remover first. I will never line a tank with any product. I took my 1950 Studebaker gas tank out today because it has liner coming loose and plugging up the fuel line. I made it home the last 35 miles by putting a 5 gallon gas can in the front seat and running a hose to the fuel pump. This was while on an all day Model A tour this past Saturday. Lucky I had the gas can, as it saved me from a 2 or 3 hundred dollar tow to get home. |

Re: gas tank
Brent. I was sure that you of all people would have realized that the rocks and cement mixer was a joke. In any case I have always believed your philosophy to open them up is the right way to go. Wayne

Re: gas tank
Brent-
Once opened, and rust removed, and any repairs made, what do you coat the surfaces with? |

Re: gas tank
Actually, the rocks are not a joke! There is a process of tumbling with roughly pea gravel sized stones put in side and it does have some, repeat some, merit. However, it is not a cure and gets rid of some of the larger scale but the rust issue is still there and coming back.
I cut them open like Brent. The best way is to cut the top off as pictured. After carefully welding back together (tig best, mig will work), test it for leaks and weld up small weeps around the welds. Then slosh with a compound. Right now, someone will have to tell me the better slosh as I have not had to do one in 5-8 years.Products have morphed. Last edited by Oldbluoval; 06-10-2015 at 12:29 PM. |

Re: gas tank
The cement mixer is the funny part in case anyone missed it. Can you visualize a gas tank tied to a cement mixer ? Wayne

Re: gas tank
What's even funnier is that the original poster created this thread with a total of 4 words. It was his first post. He hasn't posted on this thread or any others. The thread is 2 pages long and he provided absolutely no details about his problem!!

Re: gas tank
As you know I'm the one that posted about the cement mixer.
Let me expand a little on rusty tanks. There are three types of tanks, ones in good shape, ones with small flakes of rust, ones with large flakes. Tumbling media, such as rocks, will beat most of the large rust out of the tank. Rocks left in the tank will not rust and would be of little problem in the future. Chemicals that remove the rust do a good job as well. Both tumbling of some kind, and rust remover would be better for the real rusty tank. Now, once the tank is "clean" what do we do? If you leave it rust will reappear where there is no gas, including the top of the tank. This will eventually cause a problem several years down the line. How many? Could be 5, 10, or 25 years from now. The bottom line repair, (Notice I did not say fix) is to open the tank, remove the rust and seal the tank metal surfaces.

Re: gas tank
I suggested strapping the tank to a cement mixer a long time ago, but you'd have to use some media that can get around the baffles. Someone lined the tank in my 1950 Studebaker that I bought a year ago, and the crap is coming off and plugging the fuel line. Yesterday I removed the tank, and today I tumbled it with my cement mixer. This tank has no baffles, and I used a few pounds of bolts and screws, mostly lag bolts. Lag bolts work well because of the course sharp threads. The tumbling did a good job of removing the rest of the liner. I set the angle at 45* so the hardware slides across the top and bottom surfaces. This means I had to flip the tank over to do both surfaces.
For a Model A tank, if you used a bunch of black beauty it would get past the baffles, but if you have heavy rust it could takes days of tumbling to remove it. My first choice would be EvapoRust or whatever the liquid is called. Again you'd have to turn the tank to reach all sides, or buy 10 gallons of the stuff. Actually my first choice would be to buy a cleaner tank, and I've passed up some nice tanks because I didn't need them. |

Re: gas tank
Thankyou Mike and Tom for your great explanation of a subject that I indeed thought was a joke. I still chuckle when I envision the tank strapped to the cement mixer but I understand what each of you are saying. I also agree with Brent that the best solution is to open up the tank to do a proper job. Thanks again, Wayne

Re: gas tank
Anyone know what dissolves a tank liner? Not sure what brand. It was put in during the 1980's. It all gravitated to the bottom of the tank and left the holes at the sides.

Re: gas tank
Ethanol will dissolve the older sealant. I used the sealant from hirsch in 1980 in my model t gas tank. Worked great until the advent of modern day ethanol contaminated gas. The ethanol melted the old sealant and filled my carb with a jelled glob.

Re: gas tank
We had a couple in the shop that had failed sealing jobs. One had the soft set type sealer from the 80s, alky fuel melted it out and we found goo clear into the intake ports. Makes a lovely mess. #2 had a thin white plasticky sealer that came loose in sheets, looked like you put a handful of bread sacks in the tank. We found that lacquer thinner would dissolve both types, we would pour in 5 gal and rotate it around, then drain through a paint strainer to see what we had. Repeat until clean. We then sealed with por15 to hold down any remaining bits. If your tank is nicely painted, you gotta be real careful not to get any thinner on the paint or it will eat it.

Yep, That's the joy of Fordbarn. No matter what the question; we will give answers! ( OK then, opinions) And I for one think he should check the condenser.
