outboard tank gasket replacement

[landbaron2]

I'm looking to restore a couple old metal outboard tanks (two standard single line and one pressurized dual line). I found the gasket kits for the pressurized tank but can't seem to find the gasket kits for the standard single line tanks. Does anyone know where I can obtain these? I'm looking to replace all the gaskets to include the caps, as they are all old, dried out, and cracked. I'll fabricate them myself as a last resort but would prefer to just buy the kit.
