The GMC fuel pump is a primary component in the fuel delivery system of your vehicle, providing a steady supply of fuel flowing through the system to keep your vehicle running at its best. The GMC fuel pump is responsible for maintaining a consistent level of pressure throughout the system to keep it operating smoothly. Located in the fuel tank in most vehicle models, the GMC fuel pump is a dependable component, supplying the fuel delivery system of the vehicle efficiently over many miles of travel. As time passes, the GMC fuel pump can begin to show the signs of everyday use, beginning to work less effectively, and can eventually fail. The GMC fuel pump rarely fails suddenly, most often it is a gradual process with a good many warning signs. If you recognize the symptoms, you can secure a replacement before it fails completely, leaving you stranded with an inconvenient vehicle breakdown. If the vehicle begins to hesitate upon acceleration, or sputters and coughs, these can be indications of an insufficient fuel supply. If your GMC fuel pump is not operating at its best, the vehicle can run or idle roughly or misfire. Other symptoms of trouble with your GMC fuel pump include poor fuel mileage and excess exhaust emissions. These symptoms in your vehicle can indicate that the GMC fuel pump is no longer maintaining the proper fuel pressure and supply to the system.

Helpful Tips in Finding the Right GMC Fuel Pump
With the task of delivering the fuel from your vehicle's tank to the engine, the fuel pump must be in top condition at all times. To get a good-quality GMC fuel pump, you should know the different types of pumps available in the market. Getting the appropriate fuel pump is the key to achieving reliable performance from the fuel delivery system.
Knowing the different kinds of fuel pumps
Generally, automotive fuel pumps are categorized into two types: mechanical and electrical. The mechanical fuel pump is powered by another component of the vehicle, usually by the engine. The electric fuel pump, on the other hand, is powered by electricity that is supplied from the alternator or derived directly from the battery.
- Mechanical fuel pumps: This type of pump was the standard system of sending fuel to the engine. Usually bolted to the engine block or cylinder head, the mechanical pump produces a suction and pressure that draws the fuel from the tank to the engine. This pump can deliver ten to fifteen pounds of fuel pressure that is adequate to feed the carburetor but not enough for the requirement of the fuel injection. With the conception of fuel injection, the mechanical pumps eventually gave way to electric fuel pumps.
- In-tank electric fuel pumps: Mostly used on street vehicles, the in-tank electric fuel pump can deliver 45 to 65 pounds of fuel pressure that is perfect for fuel-injected vehicles. Because it is located in the tank, the pump is kept cool when submersed in fuel or by getting unheated fuel during its movement through the fuel connections.
- Inline electric fuel pumps: This type of electric pump can be placed almost anywhere in the vehicle where the ground line can be connected to the frame. The inline electric fuel pump is suitable for racing cars and other vehicles that have been upgraded from a carburettor to fuel injection system. On some instances, the inline pump is used to fill in for a defective in-tank pump if taking out the tank is going to cause issues or create more repair problems.
Identifying other relevant components
When purchasing a new GMC fuel pump, you should also know the relevant components involved. If you choose a mechanical pump, a good carburetor is required to mix the correct amount of fuel and air for the engine to operate smoothly. For an electric pump, a fully functional fuel injector is needed to transfer fuel properly throughout the vehicle.
Other things to consider
Usually, car collectors will need mechanical fuel pump since this is commonly used in older vehicles while a new vehicle model needs electric fuel pump. Taking out the demand for a carburettor to transfer gas at low pressure, the electric fuel pump is more efficient. If you want cheaper alternative, you may opt for a one-size-fits-all pump or a remanufactured pump, although both of these options may not work as well as brand-new fuel pump. Safety measures must be considered if you choose to purchase these two types of fuel pumps.
