Question 1. I have an older jet that I am trying to get back into the air a hotspot. When it was built by the original owner he put the fuel tank in so it could not be removed. Well when I put the plane away I emptied the tank the best I could. How do I and what do I use to flush the tank out with to ensure there is no mold in the tank. I was thinking of using some acetone but not sure if that would hurt the kevlar tank or not. After flushing it with the acetone I was also going to fill and flush with Jet A fuel to get the acetone out. What do you guys think?

Question 2. Same jet. When it was originally built with screws through the top of wing as a mounting method instead of the wood tongue method. I don't have the complete measurement for that piece of wood. I know it is 5 ply hardwood which is 1/4" thick, and 1/2" wide I just don't know how long that piece is. Does someone have a measurement of that length?

Thanks,

Patrick
