Fuel Systems are particularly important on diesel trucks, whether you drive a Ford, Chevrolet, or Dodge pickup. At Melvin's Auto & Truck Repair in St Augustine, fuel system maintenance and repair is a service we prioritize, since we know how essential a reliable fuel system is.

Obviously, the dirtier your fuel system is, the bigger the improvement you will see in performance and fuel economy after a fuel system cleaning. But it is important not to wait until your system is running poorly. If you do, by the time you get a cleaning, you’ve wasted hundreds of dollars in gas or even possibly damaged your fuel injectors and catalytic converter.

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.

Your drive belts run everything - your AC, power steering, alternator, and water pump are all dependent on the belts that turn them. At Melvin's Auto & Truck Repair in St Augustine, FL, our goal is to keep your truck maintained, so you’re never stuck out on the road. Drive belts are a critical part of that goal.

In the diesel world, "blow-by" is a term you're bound to run across at some point if your line of work involves diesel-powered vehicles of any kind. What is blow-by, what causes it, and how concerned should you be? At Melvin's Auto & Truck Repair in St Augustine, FL, our fleet maintenance and diesel technicians see it on a regular basis. Here we'll take a quick look at blow-by, correcting it, and preventing it.

What is Blow-By? - Diesel blow-by is a term that describes an event of lost compression into the crankcase. Blow-by occurs whenever a burnt or unburnt fuel and air mixture escape from the cylinder and past the piston rings and into the crankcase. In a perfect world, the piston would be sealed tightly in the cylinder, able to move up and down but keeping all the air and fuel and exhaust that enters or exits the cylinder during the combustion process out of the crankcase. As you'll see, this perfect world doesn't exist, but it is important to minimize the amount of blow-by in a diesel engine.
