Gas Tank derusting

[rktmanfj]

Randy, I have had good luck using ZEP brand Calcium lime and rust remover diluted 50/50 with water as a rust dissolver/converter. If there is heavy scale drop in a handful of steel nets to shake around and knock the scale loose.

Let the mix soak in the tank overnight and then chase with a small amount of baking soda in distilled water to rinse and inspect. If you don't get all the rust the first time simple pour the mix back in and try again the next morning...

Once you are sure you got it all rinse with denatured alcohol and dryit out with compressed air.

Phosphoric acid works much faster but can quickly ruin paint. The CLR is far more forgiving.

Thanks, Bill!

To plug up the filler and the fuel gauge hole just go to your local pool supply and get a #10 winterizing plug for the filler,and a #6 for the fuel gauge hole. They fit perfectly.
