PRODUCT DETAILS

An GM Original Equipment Mechanical Fuel Pump is a GM-recommended replacement for your vehicle’s original components, and is a diaphragm positive displacement pump. A rocker arm driven off the fuel pump camshaft lobe moves the diaphragm, causing fuel to be drawn in through a one-way inlet reed valve. As the cam lobe rotates away from the rocker arm, a spring pushes the diaphragm back, pushing the fuel out through a one-way outlet reed valve to the carburetor. This original equipment fuel pump has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

FAQs

Do I need to buy a specific version of this pump to fit my particular vehicle?
Yes. Refer to a parts catalog for specific applications.

Are there benefits to replacing my fuel pump with an original equipment fuel pump?
Yes. Original equipment fuel pumps have gone through the same rigorous testing and meet the specifications of the production pump your vehicle was built with.

Will my fuel pump always exhibit warning signs if it is failing?
No. Noise, vibration, exhaust smoke, warning lights, hard starting, stalling, and hesitation can all be signs of a failing fuel pump. However, it is also possible that none of these signs could be present.

Are there ways to test my fuel pump to see if it is performing efficiently?
Yes. Inspecting fuel pressure and/or examining engine data and codes with a scan tool can help determine potential concerns.

Are there preventative measures I can take to help prevent/minimize fuel contamination that could damage my fuel pump?
Yes. It is good practice to refuel with high quality fuel from well known, high volume, trusted fuel stations whenever possible.

Could special tools be required for fuel pump installation?
Yes. Special tools may be required, e.g., a wire connector crimper, fuel pressure gauge, and lock ring removal tool.

MAINTENANCE TIPS

  • When you replace a fuel pump, it’s important to determine what caused the previous fuel pump to fail. Not diagnosing the problem can lead to more of the same in the future.
  • For proper operation and longevity, it is critical to have a clean fuel system. If there are any signs of contamination, follow the manufacturer’s service information to thoroughly clean the fuel system.
  • When replacing a fuel pump, you need to check for proper pressure, volume, and flow. The specs that don’t measure up require further investigation into the entire fuel system.
