Shopping for Gas Cap

Gas Cap Shopping Info

How Much Is a Replacement Gas Cap?

A replacement gas cap can cost anywhere between $10 to $30, depending on the vehicle model. Gas caps are typically sold individually. Some gas caps come with a lock and key, while others are simply screwed in. 

What Is a Gas Cap?

A gas cap is a seal that’s used to seal the fuel tank to prevent fuel from leaking out, while also keeping contaminants out. It’s important that a gas cap doesn’t have leaks, because any fuel or fuel vapors can leak out and can ignite. Vapor buildup inside the gas tank is necessary and the engine may actually develop issues if the gas cap isn’t doing its job.

Shop for Gas Caps Here at CarParts.com

After some time, the rubber around the cap can wear out. The rate by which it degrades varies depending on the environment the gas cap is exposed to. If you know your gas cap needs a replacement, you don’t have to worry, because getting replacement gas caps is easy and convenient.

Here at CarParts.com, we have high-quality gas caps at affordable prices! Why go to dealerships that will charge you exorbitant prices for a simple replacement? You don’t need to worry about quality, because all our parts are sourced from industry-leading manufacturers who ensure that each part goes through strict quality control standards and meets OE specifications.
