For Gasoline(methanol blend) I add 4 ounces of Marvel Mystery Oil, to a full tank. Others complain of vapor lock... Mine hasn't vapor locked with Marvel Mystery Oil. For new tail light gaskets ; try CARS old Buick parts FUSIK auto parts Rock Auto parts I got sockets and bulbs at NAPA ... my original were pressed in brass pieces. I was able to make do with some steel sockets that slipped into place. They're working well after ten years. For the reflectors, white paint seems to reflect better than silver paint....
