Fuel Pump Assemblies FAQs

What is a fuel pump assembly?+

A fuel pump assembly is a complete unit that includes the fuel pump, fuel sending unit, and often times other components like filters and pressure regulators. It ensures proper fuel delivery from the tank to the engine while also monitoring fuel levels.

What’s the difference between a fuel pump assembly and a fuel sending unit?+

A fuel pump assembly includes the fuel pump and the fuel sending unit, which measures the fuel level in the tank and sends that information to the fuel gauge. The fuel sending unit is a key part of the overall assembly but can also be replaced separately if needed.

When should I replace my fuel pump assembly?+

You should consider replacing your fuel pump assembly if your vehicle experiences difficulty starting, reduced fuel efficiency, or inaccurate fuel gauge readings. A failing fuel pump sending unit or fuel pump module assembly can lead to these issues. For more information, follow our guide to diagnosing a bad fuel pump.

What is a fuel pump module assembly?+

A fuel pump module assembly is just another name for fuel pump assembly. These units provide an easy drop-in installation to help get your vehicle up and running fast while ensuring you have replaced all crucial components of your fuel pump system.

How do I know if my fuel sender unit is failing?+

Signs of a failing fuel sender unit include inaccurate fuel gauge readings or erratic fuel level displays. If you’re experiencing these issues, it may be time to replace the fuel sending unit or the entire fuel pump assembly.

Are Quantum’s fuel pump assemblies compatible with my vehicle?+

Quantum offers a wide range of fuel pump assemblies designed to fit various makes and models. You can use the Year, Make, Model search function on our website to find the correct fuel pump module or fuel pump sending unit for your vehicle. If you’re still having trouble, contact our customer service team with your vehicle’s year, make, model, and OEM number for assistance.

Why should I buy a fuel pump assembly instead of a fuel pump replacement kit?+

A fuel pump assembly includes not only the fuel pump but also the fuel sending unit, wiring, and other necessary components, providing a complete, ready-to-install solution. This ensures all parts are compatible and working together efficiently, reducing installation time and the risk of errors. In contrast, a fuel pump replacement kit may only include the pump and basic replacement items, and may require reusing old components, which could lead to compatibility issues or premature failures. For a hassle-free, long-lasting solution, opting for a fuel pump module assembly is often the better choice.

Why is there fluid in my new fuel pump assembly, and is it safe to use?+

The fluid you may find in your new Quantum fuel pump assembly is testing fluid used during the manufacturing process to ensure the pump operates correctly under real-world conditions. We test pumps with fluid to check for proper flow, pressure, and functionality. This fluid is harmless and will not negatively affect your fuel system. It's completely safe to install and operate a pump that contains residual testing fluid.

Our Fuel Pump Assembly category offers a hassle-free solution for your fuel system needs. Each assembly is designed for quick and easy drop-in installation, saving you time and effort—no tools required. These full fuel pump assemblies include everything you need in one complete package, from the fuel pump module to the fuel sending unit and hanger.

Upgrade with confidence, knowing our fuel pump assemblies are engineered to save you both time and money, while delivering the dependable performance your vehicle demands.
