Getting the right amount of fuel into your vehicle’s engine is crucial to its overall performance. This is why you’ll need a reliable fuel pump assembly. Once this pump fails, don’t be surprised if you experience an engine that sputters when driving at high speeds, power loss when speeding up, an engine that won’t start, surging, and sudden power loss when your car is under strain. Sometimes, the only solution to these problems is to get a replacement. But before you grab the first pump assembly you see, ask yourself or a retailer these questions first to make sure you’re getting the right part:
Questions to ask yourself:
Do I need an in-tank or an inline fuel pump assembly?
Depending on your car make and model, you’ll either need a new in-tank or inline electric pump. To make sure you get the right replacement, take a look at your car manual or simply take note of your vehicle’s old pump type. Replacing an in-tank type assembly is trickier than when replacing an inline type because an in-tank might require you to remove the fuel tank first.
Does my car use a mechanical or electrical pump?
Old cars or antique vehicles that use carburetor-based engines are most likely equipped with a mechanical pump, while modern cars with fuel injection systems rely on an electronic fuel pump. This because a mechanical pump won’t be able to generate the amount of pressure needed by a fuel injection type. So if you have a carburetor-based engine, your pump assembly is most probably a mechanical type. If your car uses a fuel injection system, you’ll need a new electrical pump.
Questions to retailer or dealer:
What other information do I need when looking up a pump assembly?
In some cases, you’ll also need the engine VIN code aside from the vehicle year, make, and model when looking for a new pump. This is especially true on certain applications such as in GM Flex Fuel vehicles.
What other factors should I consider aside from pump assembly type and car specs?
A lot of pump kits look the same on the outside but may actually have different pressure ratings and flow rates. Consult your vehicle manual or a mechanic to determine your old pump’s specs to make sure you get the right part.
