Rust in gas tank
I have 5 model A's at the present with one that has always had fine rust in the tank that I never have been able to keep cleaned out. In the past I would run an extension magnet to the bottom of the tank and clean what I could out but still would have the pencil filter to stop up and also the filter in the carb with real fine rust. This could be a trick everyone already knows but I came up with the idea to put a strong magnet with a small eye bolt screwed in it positioned on the bottom of the tank. About once a year I reach down and hook the eye bolt and pull out about a half a cup of fine rust. I used to travel about a hundred miles before having to blow back in the gas line to clear the pencil filter and maybe clean out the carb filter. Since I have been using the magnet I have never had to clean the filters. I know this may sound like a band-aid fix but it has worked for the last 5 years for me. Also I saw some magnets at Harbor Freight that would work that already have a loop made on top.

Re: Rust in gas tank
Have you considered trying a dirty leg to catch the rusty crap?

Re: Rust in gas tank
why don’t you just clean the tank properly once and for all and get Rid of the rust and the irritant or buy a replacement tank?

Re: Rust in gas tank
If your car is a 28 or 29 it could be an easier fix than a 30 or 31.
We had the same problem many years ago on our keeper 29. The gas tank is not that difficult to remove. We than sloshed it twice. Making sure we took our time, and got the sealer everywhere. It has now been over 30 years. Fingers crossed, we have had no problems since. We also do not leave car setting with a tank full of gas. In the winter, we run it down to almost empty. Go luck. Enjoy. |

Re: Rust in gas tank
This works 2 quarts of 3/4 stone some water and detergent and I put it in my cement
mixer and walked away. couple hours of that turn tank up side down let it run. Rinse and repeat . Now pure steel nothing. You need the 3/4 stone cause its processed like sharp diamonds..plus soap and water. not redneck but amazing results. |

Re: Rust in gas tank
Evaporust can be purchased at Home Depot or Harbor freight. Buy 10 gallons. Fill the tank with it. It turns the rust into liquid and you drain it out. Works well. It is a product made to do exactly what you need. I have used it on many tanks with 100% success. Regarding off season storage, you are always better leaving the tank full of fuel. Rust occurs when the tank has no fuel in it, due to condensation and humidity. If the tank is full of fuel, it cannot rust.

Re: Rust in gas tank
I used to have the standpipe and pencil filter. -and would still have problems, took them out, filled and sloshed -- drained till most was gone, left the standpipe/filter out, went for a long drive and cleaned the filter every night, after about a thousand miles of driving there was no more accumulating in the filter.
