"There are only certain plastics that Acetone attacks violently. One of the big ones is ABS. You can actually use acetone as a glue to reattach broken ABS pieces."

I worked in a plastics shop during college. We used to make a dense plastic glue by mixing acetone and PVC plastic chips. Acetone is not something I would recommend to put in the fuel tank. In addition, watch your paint finish don't spill it if you try it out.

We did the same thing at my last job in our model shop. That stuff is awesome when used properly. Unfortunately, I have a bad feeling some components in the fuel system would be destroyed if this is tried.
