    you have been watching too many crime scene shows. In order to print your truck they make a mess for one thing and then you need to get prints of everyone who may have left prints on your truck and if it was possible to lift a good print you would have to have a viable suspect to match the print to. To randomly run prints with no suspects unless a serious crime is just to make the victim feel good and usually the clean up afterwards lessens that feel good feeling..besides crawl under your truck with a drill and see what you really need to touch to drill a hole in the tank.

    Most plastics are a "low surface energy" material meaning that they are very difficult to repair using conventional glues due to their slippery surface. If you tried to use JB Weld, for instance, chances are that the repair would not hold up.

    You could try plastic welding and they sell welding kits for this, however, aside from the danger of applying a hot iron to a leaking gas tank, these kits were not meant for such critical purposes.

    Many areas have professional plastic welders, they usually repair plastic boats such as kayaks. They might be able to help you.

    Might I also suggest to always carry comprehensive insurance on any vehicle you feel is worth it, even an older vehicle. It's usually nowhere near as expensive as collision insurance and covers vandalism as well as fire and theft.

    Gas tank is made from polyethylene and has extremely low surface energy like HAL9001 mentioned. The only way to properly fix it, for long term reliability, is to melt the polyethylene with a plastic welder and filling the hole with molten polyethylene. Any type of patch or filler will not produce a chemical bond only a physical bond and eventually will leak.

    The suggestion of finding another tank is probably the best option.

    The vandals will eventually pay...."for the wages of sin is death".

    Please see attachment. First paragraph says "not for use on plastic fuel tanks".

    Again, there is nothing that will seal the Plastic gas tank properly except for "plastic welding" repair with the same material as the tank. I believe the tank is constructed from HDPE (high density polyethylene).

    A Plastic welder melts the polyethylene and fuses it together with additional polyethylene material, if needed. If the hole is small enough, you may be able to melt the area around the hole and force molten plastic into the hole, sealing it...otherwise you will need additional molten HDPE to plug the hole. The product has to be in the liquid state in order to bond properly and prevent future leaks.

    Plastic tank? I got a hole in a metal one once and got JB Weld and cleaned all around then dipped a sheetmetal screw into the JB Weld and tightened it. Never leaked again. Not sure if it would work on a plastic tank?

    Use the Plastic screws, make sure you have the proper size and pilot hole, put some J/B weld on it and call it a day.
