My bad... I believed what Google returned, I know better!interesting Tim. I removed the fuel/oil seperator piece and am figuring out how to reseal it and having it stay while the sealant hardens. Smaller hands would make it go easier. Thinking of putting JB weld on the edges of the J piece and then inserting it into the tank. May have to try some dry runs to see if my hands can place it w/o falling into the fuel tank.
Does your son/grandchild have a dart gun? A nerf style might work better than the old stiff shaft type. A little petroleum jelly to help it stick might be a good idea. If necessary a dowel can be forced into the non suction cup end.
