At National Brake & Muffler in Griffin, GA, we understand the importance of doing things right. That’s why we are in the business of hiring ASE certified technicians. After all, your car, truck or SUV is only as good as the quality of service it receives.

fuel being put into vehicle

Your car’s fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. Check your car’s fuel system regularly or immediately if you smell gas or suspect a problem.

What does it do? - The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

At National Brake & Muffler in Griffin, our expert mechanics understand the importance of good quality oil, changed at correct intervals, in allowing you to get the most out of your Cummins, Powerstroke, or Duramax diesel.

Now that you’ve got an idea of the components that make up a diesel system, and what they do, understanding how the system works in a more cohesive way isn’t difficult. At National Brake & Muffler in Griffin we understand what’s going on in your fuel system while your diesel engine is running.

Your vehicle is a vital part of your life; it takes you wherever you need to go and can last you a very long time if taken care of properly. A part of the care it takes to maintain the vehicle is taking it to repair shops in order to receive any necessary maintenance or fix any problems you may be experiencing.

If you drive a vehicle with more than a few miles on it, there’s a good chance you’ve noticed an occasional drip underneath it that leaves spots wherever you park. Identifying what is leaking from your car will help you determine whether or not it’s a cause for concern, and what to do about it.

There are seven liquids a car can possibly drip: oil, gas, brake fluid, transmission fluid, gear oil, water, and coolant. How do you tell the difference? This article aims to help your know-how.
