All About The Fuel Pressure Regulator- Does It Need To Be Replaced?

Those of us that have at least a fundamental knowledge of automotive repair also know just how vital the fuel pressure regulator can be to the working order of a car. Despite the thought by some novice mechanics that it is overly complicated, the fuel delivery system is actually relatively simple. You pump the gas into the car, and then it is stored in the fuel tank before it makes its way to the engine. However, between being stored in the fuel tank and being transferred to the engine, the gas must first go through the fuel pressure regulator. Read More


Beginner's Guide to Tools and Instruments

Tim Allen once said, ''I have a thing for tools.'' More than likely, he has a different tool for every job. If you are someone that does mechanic work out of necessity, and not because you have a passion for the work, sometimes it's hard to know exactly which tools are necessary and which ones you can do without.

While those of us that enjoy working on vehicles usually try to accumulate as many tools as possible, there are ten no one should be without: Read More

Fuel Pump Failure - Knowing the Nightmare, But Not the Cause

A problem with your vehicle's fuel system is one of the most frustrating automotive issue experiences you can have. Unlike a dead battery, a flat tire or an overheating engine, sometimes problems with the fuel system aren't definitive. While sometimes the vehicle won't start at all when you have problems with the fuel system, other times the motor still runs and you can drive the vehicle. However, in this situation, the vehicle won't run to its full potential and it will sputter, putter, and lurch its way down the road. Read More

Avoid These 5 Fuel System Diagnostic Errors

 As auto manufacturers keep striving to improve car engines and their fuel burning efficiency, fuel systems incars keep getting more and more complex. A phenomenon that's arisen as a result of these innovations is that fuel delivery issues are being misdiagnosed. In some cases, technicians have been returning brand new fuel pumps thinking they are defective, when in fact the actual cause of the issue was a defective fuel pump relay or crankshaft sensor.

6 Factors That Affect The Fuel Pressure In Fuel Pumps

To have proper delivery of fuel at correct flow rates and pressure from gas tank to fuel injectors it is essential to maintain steady gasoline supply in the fuel lines. Proper fuel delivery is essential for maintaining good engine performance.Read More

Finding the Correct Fuel Pump for Specific Applications

It is important the correct fuel pump replacement is sold and installed in the specific applications. There are several factors that are important considerations in looking up the application-specific fuel pump. Also, GM uses several different in-tank sender assemblies for the same make and model of vehicles. Read More

Choosing Between Mechanical Fuel Pump And Electric Fuel Pump

The purpose of fuel pump in an automobile is to deliver fuel from the gas tank to the fuel injector or carburetor at the necessary pressure. Fuel is drawn from the fuel tank and is propelled into the internal combustion engine through a fuel pump where the combustion of fuel occurs with air. Regardless of the external conditions, a fuel pump has to facilitate the delivery of right amount of gasoline from the tank to the engine through a fuel line at a specific pressure. In automobile engines, some fuel pumps are mechanically operated with low pressure fuel distribution, whereas others are electric pumps that push the gasoline to the engines at higher pressure.Read More

Is Your Fuel Pump Going Bad?

There are several warning signs that your fuel pump may go bad before it actually does.

Some Fuel Problems Are Electrical Problems.

When an engine is running poorly or not at all, there's a tendency to blame the gas. Either it's “bad gas” or a bad fuel pump.

How to Change a Fuel Pump: The Basics

Changing a fuel pump is a fairly simple task for most shade-tree mechanics. However, in addition to mechanical know-how, the job requires the willingness to get a little messy.

Electric Fuel Pump Testing

Most vehicles with fuel injection utilize an electric fuel pump located in the fuel tank to supply sufficient volume and pressure to the injectors. Fuel is under pressure as it enters the fuel injector.

Prevent Fuel Pump Failures Caused by Contaminants

 One of the main causes for fuel pump failures is contaminated fuel. Visible and invisible contaminants can damage the new fuel pump.

Looking After the Fuel Pump Strainer

When you remove an electric fuel pump from a gas tank you'll notice a filter or sock on one end. This is what's called the "strainer." It might look like an afterthought, but it's an essential part of the fuel delivery system.

Is It Really Fuel Pump Failure?

It is important to check everything else before you do a costly and perhaps unnecessary fuel pump replacement. Look for electrical problems, bad wiring, a short, split hoses, a vacuum leak or a clogged fuel filter.

Dissecting an Electric Fuel Pump

When you order a fuel pump for your vehicle, you may be surprised to see it in a huge box. That is because you must replace the entire fuel pump module or hanger instead of just the fuel pump. Some units are “open” so you can see the pump, sock, filter and wiring; and some of “closed” so you see a large plastic cylinder.

Two Types Of Fuel System For Automobiles

In a vehicle, the fuel system has a simple function of delivering fuel to the carburetor. The peculiar thing is that the engine never requires a steady amount of fuel. Its demand keeps on changing with the dynamics of driving. Sometimes engine accelerates and sometimes it is braked. This requires that fuel system of our car should have proper controlling mechanisms. Read More
