I want to place a metal patch on a Zinc-Coated steel gasoline tank opening.

Are you planning a gravity feed of the gasoline to the generator, or some kind of fuel pump?

Only gravity. That is how the original fuel tank feeds the engine. My external tank is about 1' higher than the original tank.

Be watchful your neighbors will be running drop cords.

Tom is a joy for a neighbor. Always has been able to bail me out.

You might consider a metal fuel line. A long rubber fuel line across the yard has the potential for damage and subsequent leaks under gravity feed. Inboard boat motors often use metal fuel lines. Coils of soft copper tubing are avail at the home despot's of the world. They are compatible with brass compression fittings.

Get a large dry chemical fire extinguisher. Water is not proper to use on a gasoline fire, as it just spreads the flames.

Might want to consider putting a vent at the bottom of one of the side walls of the gasoline storage shed to prevent the buildup of gas fumes which are very explosive.
Gasoline fumes are heavier than air which is why the vent goes at the bottom—probably would want to screen it in some way to keep the critters out
