Default 2003 Silverado Fuel Tank Vent

Hey all,
I have been having issues with starting my truck recently and it stems from not being able to hold fuel pressure after the truck is shut off. I thought it was a bad fuel pump or seal but when I pulled the bed to change the pump I got a surprise. Some rodents have been chewing on the fuel tank vent valve at the rear end of the tank. Can this valve be replaced and if so, could you point me in the right direction to a repair part? If a new tank is needed, where would one find one as nobody seems to sell tanks for the NBS trucks anymore.

you need a tank. pick and pull bone yard
if its a fuel system with a return hose and an external fuel filter...change the fuel filter or you will void the pump warranty.
