Fuel Systems

Bring your vehicle to Crawford’s Auto Repair for fuel system maintenance and repairs.

fuel systemThe fuel system is the system which pumps fuel into the cylinders of the internal combustion engine and mixes it with the perfect amount of air for combustion. There are two types of fuel systems: fuel injection and carburetors.

Prior to 1985 most vehicles (almost all of them) used a carburetor. A carburetor is a primitive method of mixing air and fuel. It is far less efficient than modern fuel injection. That’s why all modern cars today are built with fuel injection.

Importance of the Fuel Filter and Air Filter in the Fuel System:

There are two filters which protect the fuel system and engine: the fuel filter and the air filter. The fuel system is very sensitive to contamination and debris. A small amount of contamination can cause severe problems in any fuel system. Therefore, these filters are critical for protecting the fuel system and engine and for maintaining proper function of the vehicle.

When you fill your vehicle with fuel from a gas station, the fuel will have contaminants. Between the fuel tank and the engine, the fuel passes through a sock filter which prevents large contaminants from passing through. Then the fuel will pass through the fuel filter which prevents small contaminants from passing. Anything that passes through the fuel filter can pass through the rest of the fuel system. Refer to the owner’s manual of the vehicle to find the manufacturer’s recommendation for the mileage at which the fuel filter should be changed.

An air filter protects the engine from dust and dirt entering the combustion chamber through the air intake system. Any dirt in the engine can cause engine wear and eventually lead to engine failure. Therefore, an air filter, like the fuel filter, is also a critical component in any internal combustion engine. The air filter is inspected with every oil change and it is changed as needed.

Computer Diagnostics

As part of the inspection that we perform during any vehicle maintenance visit and/or with every oil change, we’ll connect a diagnostic device to the vehicle’s computer which will give us diagnostic codes. Some of these will be for the fuel system, especially since the computer plays a very specific role for regulating how much fuel is injected into the engine while the engine is running.

If your car is in need of any fuel system maintenance or repair, bring it to Crawford’s Auto Repair. We offer free shuttle service, free inspections, and a price match guarantee. We’re certified technicians with over 35 years of combined experience. We treat each vehicle as if it belonged to our own mother, and we never try to sell unnecessary repairs.
