Never use an incandescent trouble light near the fuel tank because the hot surface of the light bulb can ignite any fuel that might spill or splash on it. Fuel vapors are heavier than air and can also travel a long distance along the garage floor. Be aware of any electrical equipment that could ignite the spilled fuel. Work with caution. 1 Park the vehicle on a solid, level surface. 2 Relieve the pressure in your fuel system. The fuel injection system operates under ver...

Flex Fuel Important Details About Ethanol Flex Fuel Designed as an alcohol fuel mixture this form of fuel is different from most others. E85 contains a much higher percentage of denatured fuel ethanol, hydrocarbon, and even regular gasoline. As the name implies the solution contains as much as 85% of the fuel ethanol. One major drawback to E85 is the vehicle must be modified in order to actually handle running this fuel. Several manufactures sell vehicles capable of using both E85 and regular gasoline, they are known as "Flex-Fuel" vehicles. They contain sensors that test the fuel to determine what is in the tank, and the  computer  adjusts the engine management system from there. Recent statistics have estimated that in the United States alone there are approximately 1,900 gas stations that are selling the E85 ethanol to the public. However, other countries in North America such as Canada are lacking in the expanded usage with only three Canadian stations selling t...

Fuel Injection Working of cars fuel injection Helpful Information The quantity of fuel that enters the engine is determined by the engine management system while using feedback data which is gathered by various sensors.  Oxygen sensors  are used to monitor the fuel mixture in the exhaust system. A fuel injector can designed to enter the intake system or the combustion chamber of the engine. The open duration of an injector is called, pulse width. Once an engine runability problem has materialized, its usually accompanied by a check engine or service engine soon light. Perform a code read  or scan to determine the problem, and the subsequent repair needed to fix the problem. A fuel system can hold pressure for several hours so caution should be used when working on these systems. Best Practices Service throttle body  and idle speed control motor with  tune up . Install injector cleaner periodically. Step by step illustrated explanation of ...

Fuel Pump Working Of A Car Fuel Pump Helpful Information A fuel injection system is more efficient than its predecessor, the carburetor , and can better operate in extreme conditions. Electric fuel pumps can experience wear and tear on the armature, brushes or bearings, which causes a gradual loss of pressure. An inlet filter sock is designed to block tank sediments. Running the fuel pump out of gas can cause premature failure. Best Practices Inspect the fuel tank for sediment when  replacing the pump . To extend pump life replace the  fuel filter  at regular intervals. Service the  throttle body and idle control valve  when replacing the fuel filter. Step by step explanation on how an automotive fuel pump works. This article pertains to most fuel injected vehicles. Step 1  - A fuel pump starts by being submerged inside of a fuel tank which is common among all fuel injected vehicles. The sump holds fuel near the pump inlet. Fuel Pum...
