Re: polyethylene 4"x17" pipe- fuel tank
I built a PVC tank for fun well over a year ago and have left it in the garage without a drop coming out of it turning it every which way I left it...
Had it sitting on Styrofoam the entire year plus and sure you know how gas eats that stuff.... not a single drop!
You should use "SEALS ALL" to connect the PVC pieces and NOT regular cement.... the SEALS ALL is gasoline proof! Found it at Lowe's in the glue section for ~$5 a tube or so
