Fuel System Repair

Our technicians at General Automotive Servicenter in Gaithersburg are skilled at troubleshooting and repairing a wide variety of fuel system issues in both fuel injection and carburetor vehicles. With over 30 years of experience in working with both diesel and gasoline engines and fuel systems, there is no problem we can’t figure out.

The purpose of a fuel system is to supply fuel from the fuel tank to the engine. During its journey, the fuel passes through fuel lines to a fuel filter and fuel injectors (or a carburetor); some newer vehicles also have a return line that delivers unused fuel back to the tank. The more components your car’s fuel system has, the more things can go wrong. Besides the quality of the fuel you put in your car, the longevity of the fuel system is also affected by your driving style, as well as how well you follow the recommended maintenance schedule for your vehicle. If you notice that your car has trouble starting, the check engine light comes on or your fuel economy significantly decreases, it’s possible one of the fuel system components is failing. In this case, you can rely on General Automotive Servicenter to get your car back on the road.

Some of the Fuel System Repair Services We Provide Include:

Engine Auto carburetor

Carburetor Repair

Although a carburetor is a basic fuel delivery system compared to modern fuel injection systems, it too suffers from common fuel system problems. Deposits and build-ups, worn gaskets and damaged valves and seals can all contribute to poor gas mileage and rob your vehicle of its power and performance. Sometimes, a thorough cleaning is all it takes to restore the efficiency of your carburetor, while in other situations a replacement of its components or the entire carburetor might be necessary. You can trust our ASE certified mechanics to get to the bottom of the problem.

Car Fuel Tank

Fuel Tank Repair

Fuel tank leaks are quite common and typically occur due to a punctured or rusted tank. A good indication of a tank leak are stains underneath the car and a strong gasoline smell next to or inside the vehicle. A leaky fuel tank is dangerous, as the dripping fuel can easily ignite from a single cigarette butt thrown out of the window. Putties and welds sold in auto parts stores are only a temporary fix and don’t always work. If you need professional repair or replacement of your fuel tank, our technicians at General Automotive Sevicenter will be happy to assist.

New petrol pump

Fuel Pump Repair

When your fuel pump struggles or fails to pump the fuel to the injectors, you may experience problems starting your car, loss of power during acceleration, as well as that pesky “check engine” light. A fuel pump has an obvious task of pumping the fuel from the tank through the fuel lines. However, it also performs an important function of creating appropriate pressure for the injectors to deliver the correct amount of fuel to the engine depending on the driving conditions. In some cases, a thorough fuel pump assembly cleaning or repair fixes the problem, but in other situations a replacement might be necessary.

Rusty Car Undercarriage

Fuel Line Repair

Fuel lines are located on the underside of the vehicle and are partially exposed to the elements. It’s possible for fuel lines to get crushed, rotted or disintegrate from old age. When the integrity of a fuel line is compromised, it may spray fuel in a fine mist, which creates a nauseating gasoline smell in your vehicle. If the leak is close enough to the exhaust or engine, the mist may even catch on fire. At General Automotive Sevicenter, we can check your fuel lines, locate the leak and fix it before it causes any damage or poses a further risk to your safety.

diesel engine detail

Diesel Fuel Injection System Service

Cars with diesel fuel injection systems can suffer from poor gas mileage, reduced vehicle power and performance loss due to deposits and build-ups within the fuel system. General Automotive Servicenter provides a diesel injection service that will restore your vehicle’s vital power and performance while increasing fuel efficiency. The diesel injection system service involves removing accumulated deposits from the entire fuel system, including the fuel lines, injector pump and fuel injectors, as well as combustion chambers. Remember, diesel injection systems should be serviced every 18K to 24K miles.
