Fuel Tanks for Chevrolet Blazer

Fuel tanks for Blazers and other models of Chevrolet cars and trucks provide your vehicle with the receptacle it needs to house the gasoline that keeps things running. Most Chevrolet Blazer fuel tanks are made from either stainless steel components or high-density plastics.

How does the fuel tank in a Chevrolet Blazer work?

A variety of components come together to help a Blazer's fuel tank perform as the manufacturer intended. While the fuel tank in a Chevrolet is responsible for holding most of the gas used to keep your Blazer going, there are a few steps the car needs to take to get the fuel to the engine.

  • Once the gas is sitting inside your Blazer's fuel tank, it enters a fuel pump. This pump is what takes the fuel out of the tank and brings it to the engine block of your Chevrolet.
  • The pump pushes the gas into fuel lines. Your Blazer's fuel lines are composed of hard metal and run from the tank to the car's engine. For safety reasons, these fuel lines are not exposed to the elements, and Chevrolet installs them in areas of the Blazer that ensure they will not overheat.
  • The gas then passes through a filter to remove any impurities on its way to the Blazer's engine. The filter keeps your Chevrolet's engine running clean.
What other components go with Chevrolet fuel tanks?

The fuel tank in your Chevrolet Blazer needs some additional accessories in order to function optimally. You should keep track of the state of these components and repair or replace them as necessary. Doing so will ensure that your Chevrolet vehicle gets top-quality efficiency and gas mileage.

  • A gas cap keeps the liquid inside the Blazer's tank, where it belongs. Over time, the cap on your Chevrolet's tank may become loose or cracked. It's important to replace the cap as soon as possible. Otherwise, it might fall into a hard-to-reach crevice or fail to keep the gas inside your tank, decreasing the efficiency of your Chevrolet Blazer.
  • Tank straps hold the entire apparatus in place. While these are not generally exposed, they can still become worn or torn over time. Be sure to check on the state of your gas tank straps occasionally and replace any that look as though they are worn to the point of failure.
  • A heat shield works to further protect your Blazer's tank from the elements and prevent the gas inside from overheating.
When should you replace a Chevy pump?

Because the pump in your Blazer takes the gas to the engine, it's important to familiarize yourself with some signs that it might be time for a replacement.

  • An increase in the temperature of your Chevrolet Blazer can be an indicator that the pump is going bad.
  • If your Chevrolet sputters at high speeds but resumes performance, there may be a pump problem.
  • Low numbers on the pressure gauge point to a pump issue.
  • Decreased gas mileage from a faulty relief valve may be a problem.
