Best Fuel Tank Caps Buying Guide
Before choosing the best fuel tank caps you should consider following options:
1. Fuel Tank Cap Types: Fuel tank caps are available in two types: rubber and plastic. The most common caps are made from plastic.
Plastic caps are more affordable, lighter and easier to maintain. Rubber caps, on the other hand, last longer and can resist damage from ultraviolet rays.
2. Size: Fuel tank caps come in standard sizes, which makes it easy to find replacements. Note the tank cap size before buying new caps.
3. Durability: Fuel tank caps are exposed to harsh conditions, so you need to get something that can withstand abuse.
Look for caps made from durable materials, such as stainless steel. Caps with rubber gaskets are also a good choice because they won’t break down as quickly as plastic ones.
4. Ease of Use: Tank caps are required to contain fuel, so they have to be easy to open and close.
Consider fuel tank caps that have easy-to-use locking mechanisms. Caps with rubber gaskets are also easier to close because they create a tight seal.
5. Cost: Fuel tank caps are available in different price ranges, so you can get something that suits your budget.
