Hello,
It would be a quick check to find where the problem exists, by choking off both of the tank hoses at the valve with vise-grip pliers and a rag, then remove the hose ends attached to the valve.
Gently loosen the pliers on the side in question to see if the tank or line is blocked or the valve is the actual problem. The valve is a simple "gate" style valve and there is really nothing to come loose or break inside them.
If there is still no fuel flow when the pliers are loosened, the blockage is at the tank or in the line from the tank is in question.
I would not be surprised if there is a slip-on rubber cap on the valve nipple or the tank nipple that someone missed during the machine assembly process. The selling dealer would not know this from their pre-delivery setup and inspection.
Those rubber caps are put in place on fittings, by the part manufacturer, to prevent bugs from making a nest in the open port fittings.
