Curious about the original as well as the reproduction in cab tanks for the 49-54 trucks.
I'd like to confirm or find an in cab tank that is not galvanized. Diesel reacts with the zinc making a fine powder that clogs filters, therefore a non galvanized tank is required for use with diesel fuel.
The 1952/3 GMC 450 with 3-71 Detroit Diesel as far as I know came with a square tank on the frame, not the standard in cab tank.
I've contacted the manufacturer about this tank, waiting for an answer.
