Something like this ?Easy option: Drill the tank, use a bulkhead fitting with a gasket that will seal against the tank.
More over the top answer: Weld a sump on the tank with its own pick up and use the fuel sending unit tube as the return. Note that a cake pan will often work as well as commercial sump kits given how much cutting and welding you'll do.
