Re: PVC gas tank question. Please help
tadd, the "cellular core" can be spotted easily from examining the end of the pipe, it will show three distinct bands of material, white, beige, white. I actually used the weaker foam core for the chamber on my spud gun but totally encapsulated it with the other fittings for safety. Although you are not working with pressure this idea would give you extra meat and strength for tapping and overall durability. Just some food for thought.
