Are gas caps a universal fit?

Yes. Although there are many different types of gas caps ranging from slow-release to cap-less valves.

Attwood offers a broad line of deck fills, featuring various mounting cap configurations and different construction materials. All Attwood deck fills meet or exceed U.S. Coast Guard and ABYC H-24 standards and regulations.

What purpose do fuel tank vents have? 

Your tank has to breathe. In order to breathe, your tank must have a vent somewhere that will relieve both vacuum and pressure. Gasoline expands in volume as it warms up and shrinks in volume as it cools down.
