A good gas tank cap prevents fuel spillage, protects against contaminants, and ensures that the fuel system remains pressurized.

Types of Boat Gas Tank Caps

I discovered that there are several types of gas tank caps available. I came across screw-on caps, push-and-turn caps, and even locking caps. Each type serves a different purpose, and my choice largely depended on the level of security and convenience I wanted.
