The Problem

Modern consumer vehicles (non-diesel) are all equipped with a rather uniform fuel system in which has many critical components that are susceptible fuel contaminants. Most vehicle owners have heard of the “quarter tank syndrome” in which it is recommended that you not run your vehicle with a quarter tank or less of fuel. Why is this? It is partially to do with cooling/lubrication, however, mostly to prevent the small particulates found in fuel from entering your fuel system. Small debris can mix in with the fuel during production, transportation, and during introduction to the fuel system (vehicle tank). Countries such as the US currently have regulated filters throughout the process, including at the pump, however, none of these are effective enough to prevent particulates from entering the fuel system. The evidence is seen in the fuel system failures resulting from the contaminants. According to studies, one of the leading causes of the following fuel system failures is due to particulates in fuel resulting from the refining and transportation process or accidental insertion (dirt, paint, etc. knocked in during fueling).

Fuel Pump

The fuel pump is an integral element of any car or truck. Given the responsibility of literally pumping a vehicle’s fuel from its tank to the engine, a malfunctioning fuel pump will always lead to total disaster. Therefore, drivers need to be aware of the common symptoms of a malfunctioning fuel pump so as to address the problem before it leads to a car or truck that won’t start.

Fuel Injector

Fuel injection is a system for admitting fuel into an internal combustion engine. It has become the primary fuel delivery system used in automotive engines, having replaced carburetors during the 1980s and 1990s. A variety of injection systems have existed since the earliest usage of the internal combustion engine.

Oxygen Sensor/Catalytic Converter

The O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust as the exhaust exits the engine. Monitoring oxygen levels in the exhaust is a way of gauging the fuel mixture. It tells the computer if the fuel mixture is burning rich (less oxygen) or lean (more oxygen). / The catalytic converter is designed to convert harmful emissions, produced by an internal combustion engine, to less-harmful elements: H2O (Water), CO2 (Carbon Dioxide) and N2 (Nitrogen).
