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.

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
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
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
There are several warning signs that your fuel pump may go bad before it actually does.
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.
As winter approaches, it’s good to note that one of the leading causes of fuel pump failure is running on a low fuel tank, especially in cold weather.
Misdiagnosis is the leading cause of fuel pump problems and returns.
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.
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.
One of the main causes for fuel pump failures is contaminated fuel. Visible and invisible contaminants can damage the new fuel pump.
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.
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.
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.
