So after I drained the fuel tank and it took hours for 3 gallons to drain, it was determined that the tank was gunked up. I pulled it today and saw a lot of gunk on the bottom and on the brass mesh sock. So I read everything I could find on cleaning the tank. Based on this here is my procedure.
- Get all the old gas out.
- pour 1/2 gallon of MEK (Methyl Ethyl Ketone) into tank and let it soak for 30 minute to 60 min.
- Pour out and was with dawn degreaser to wash the inside.
- Use pressure wash to assure all is clean.
- Dry out.
- Pour in some Etch & Prep (Phosphoric acid to neutralise any rust)
So I have some questions, any input on what I am using? I selected MEK because I watched a test by this guy who had and old fuel tank with an inch of dried varnish on the bottom, he pulled it out and cut up pieces to test how well different recommended solvents worked. He tested a dozen different solutions including gas, deiseal fuel, digresser, fuel treatments, commercial fuel tank cleaning products and others. In the end the three best where as follows in order from least to best. Acetone, Denatured Alcohol and the best was MEK which completely dissolved the gunk in 30 minutes. MEK is like Acetone on steroids.
The final question is do I use Fuel tank sealant, I had heard this are not good but wanted to ask what you think.
