Ok here is a question,if I am running a fuel tank in the cowl area(model a original)could you also place another tank in line lower on the chassis and would it have to be vented above the original tank, or vented at all.Would like to add fuel amount without having to take away from the rear seat area as so many A owners seem to do.Or who nows of a narrow tall tank that fits in the rear of a A sedan.Ideas please.thanks
