Fuel System Service and Repair

fuel_savings

To keep your vehicle operating at its peak, the fuel system must be maintained through periodic preventative maintenance.  A proper tune-up also includes inspecting, servicing and/or repairing the fuel system components that deliver fuel. Our expert trained technicians will recommend repairs and servicing to ensure smooth, reliable acceleration, good fuel mileage and a strong running engine.

The fuel system of an automobile simply moves fuel from a fuel tank to the engine, where fuel is combined with air and introduced into the engine. Combustion/ignition of the fuel in the cylinders produces the energy that powers the engine. Modern fuel systems are controlled by complex electronics, but their basic operation is simple.

 

 

Fuel System Cleaning and Decarbonizing Service 

 

Engines are being built with the environment in mind, and have more emissions and fuel control systems than ever before.  Gas refiners have moved to lower quality crude oils which produce fuels with poor combustion characteristics.  Today’s fuels also contain ever increasing amounts of ethanol which cause many more engine and fuel system problems.

At the same time producers are including fewer detergent additives. These factors contribute to the build-up of carbon deposits within the engine which have been proven to hinder a vehicle’s performance and fuel economy.  Dales recommends a fuel rail decarbonizing injector service every 60,000kms.

Common Fuel System Repairs and Servicing 

 

Fuel Pump Replacement

The fuel pump is the part in your vehicle that pushes the fuel from your gas tank to your motor.  The pump will generally show signs of failing before it stops working.  Weak fuel pumps are not always easy to diagnose. When they are first starting to fail, fuel pumps can often falter intermittently. They also tend to expose this problem at highway speeds more often than at an idle. The problem is that a failing fuel pump will often mimic other symptoms of mechanical failure while in the early stages.

 

Fuel Filter Replacement

The fuel filter is one item in the system that needs to be replaced periodically as recommended by your vehicle manufacturer. The fuel filter is designed to trap tiny particles in the fuel supply and prevent them from entering the more delicate parts of the system such as the fuel pump, carburetor or injectors. When these particles build up in the fuel filter, they prevent the proper delivery of fuel and the filter should be replaced.

 

Fuel Injector Replacement

Fuel injectors are a key part of modern automotive systems, as they’re responsible for getting gasoline into the engine in a precise, orderly and carefully engineered pattern.  Fuel injector manufacturers say their fuel injectors have a life expectancy of 1 billion  cycles. Essentially, that means that the fuel injectors should last as long as the car does. Unfortunately, the conditions you drive in are not ideal. Pollution is in the air, and fuel can be contaminated with water, dirt particles and other debris. Even though injectors are designed and tested in factories where engineers compensate for real-world factors, there are always unknowns and variables. Gasoline of unreliable quality, destructive driving circumstances (such as stop-and-go traffic) and your car’s overall condition can add up, causing premature fuel injector failure.

 

FUEL PRESSURE REGULATOR
