Your engine needs a steady supply of fuel to run, and the component responsible for getting your fuel from the gas tank to your engine is your Chevy 4x4 fuel pump. Your fuel pump may be either mechanical or electrical, but regardless of the type, you will find it located inside your gas tank. Though it may seem strange, there is a good reason for your 4x4 fuel pump to be immersed in your fuel supply.

The fuel pump is a hard-working, rugged piece of equipment that is constantly running whenever your engine is on. As it operates, it generates heat.

Since your Chevy 4x4 fuel pump does not have a fan to keep it cool, and does not receive any cooling effects from moving air as you drive, it uses the gas in your tank to dissipate heat. An overheating 4x4 fuel pump will damage its moving parts, and once your fuel pump goes, you will have no choice but to replace it. This is one reason why it is important to keep some fuel in your tank at all times, particularly if your vehicle is fuel-injected. Another good reason to keep your tank partially filled is the rust and sediment that builds up over time in the bottom of your tank. Once your Chevy 4x4 fuel pump runs out of fuel, it will try to pump this sludge through your system. Of course, this is going to clog up the works and damage the pump. You should also make sure to change your fuel filter according to the manufacturer’s recommendations in order to keep as much debris out of your fuel supply as possible.You will find a full line of replacement 4x4 fuel pumps and fuel filters in our online catalogue.
