Vapor Line Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a '73 GMC I am piecing back together. The vapor canister is gone. The vapor line ends near the steering box and is just open (see image). Can I just put some type of breathable filter at the end of the line? Or should I try to find a canister and gather up all the parts to put it back like it originally was? There is no smog test here in rural Texas, so that is no problem. Has anyone used a filter on the end of the line? If so, what type of filter? Would I also need a vented fuel cap?
