I need good advice.
The gas tank on my GL looked bad- no severe scale, just rusty. I was advised to remove it, use phosporic acid to clean it. I did so and was left with a few areas that prob need a longer soak.
I had thought to use a coating like por-15 but was concerned it would clog the pickup screen and tube. My intention was to just fill it with gas and let the petrol fumes keep oxygen to a minimum and thus stave off future rust.
Then i met a guy who said i better re-line or get another tank. So i found a good used tank with just one spot of rust in the bottom. I went ahead and soaked that tank in apple cider vinegar because i didnt want to destroy the factory lining.
All kinds of junk came out so i left just a cup of the solution in the bottom assuming the rest of the tank would be fine. I had it in a small room with a large dehumidifier running. There were stains on the walls of the tank i thought were from the crap that had been knocked loose but not rinsed out.
2 days later i dumped the remaining apple cider vinegar and washed it through but its a mess. Rust everywhere.
So off to walmart and putchased 6 gallons of white vinegar. Its been 2.5 days and theres a lot of rust. Its slowly turning black but seems like new places are rusting up. Its crazy.
What am i doing wrong? Now my original tank looks better!! I saw good rust remover what you can say about it?
Is apple cider vinegar too strong? Was the factory lining on its way out? Can i por-15 the tank without clogging the pickup tube (i read one account of the brass screen turning to "glass" afterwards. Should i just use my original tank without a lining?
