This can be a daunting task for some but if a person is rightfully equipped with the knowledge and the right tools then they should be able to tackle it.

Optimum vehicle gas mileage is dependent on, and influenced by, a variety of factors, including the health and function of a vehicle's engine, fuel induction system and supporting systems. A...

A fuel pump is an integral part of a vehicle's fuel delivery system that bolts directly to the side of a vehicle's engine block. A fuel pump has a long, slender metal rod, otherwise known as a...

This job is simple in its steps, yet it does require much patients, a lot of elbow grease and a couple of hours.

Fuel pumps, the majority of which are of the mechanical variety, are operated and driven by engine camshafts. Camshafts, which are located deep inside vehicle engines, are long, narrow metal or...

All fuel-injected vehicles have fuel pressure regulators to maintain a regulated amount of fuel flow. Fuel injectors require a set amount of pressure at the nozzle at all times while in operation....

The electric fuel pump came into wide use on vehicles when fuel injection was introduced. This is due to the increase in fuel pressure necessary for the fuel injectors to work. Conventional...

There are two types of superchargers: roots type and centrifugal type. Both types force air into the intake manifold. This is known as "forced induction." With more air being forced into the...

A Hyundai's engine is compoised of various mechanical parts, sensors and other electronic parts. Any one of these parts could make a Hyundai engine shut off or stall. To understand how an engine...

Most cars and other vehicles have at least two oxygen sensors; some have four. If there are two oxygen sensors, there will always be one in front of the catalytic converter and one behind it. If a...

A pump gas motor is a complicated piece of machinery that contains many moving parts, at least one computer and various sensors and wiring. All of these things work together to provide horsepower...

Engine intake manifolds bolt directly to the top of vehicle engines by way of a series of long, threaded bolts, which provide a secure, solid attachment. An intake manifold provides the structural...

Hydrogen is definitely explosive and another source of alternative fuel. The hydrogen-fueled Hindenburg airship crash in 1937 proved hydrogen's ability to burn. It is also simple to produce in...

The actual mechanical design of a fuel injector is less complicated than what makes it function. A fuel injector is an electromagnetic device that accepts fuel through a screen filter into a...

A cool or cold air intake can make a significant difference in horsepower and fuel economy when properly installed. The theory behind a cold air intake has been used for many years in aircraft,...

Most diesel fuel comes from crude oil. This oil is then refined through a process called fractional distillation, which separates the actual fuel from the less burnable and more viscous parts of...

Without fuel, the car will not start. The fuel pump is the only thing that moves the fuel from the fuel tank to the engine. There are several reasons for a fuel pump to fail or not come on. It is...

Early model vehicles used a carburetor to get fuel into a car engine. In carbureted vehicles, fuel is picked up from the fuel tank by an engine-driven fuel pump. The fuel travels to the...

There are only a few things that would cause a car to stutter or have a hard time running for the first few minutes after start up. Starting off with older cars that still use a carburetor, the...
