Fuel Pump Assembly Products

Fuel is your engine's food. This substance needs to be fed to the engine regularly so that it functions properly. Now, to ensure that the engine gets its daily dose of fuel, it relies on the fuel pump. However, the fuel pump can't do the job alone. It also needs the help of other components. These parts are what make up the Fuel Pump Assembly. Aside from the fuel pump, this assembly contains an electric pump motor that powers the pump. There's also a cylindrical plastic enclosure that houses the fuel pump and motor. A specialized spring-loaded frame is also included to give the enclosure the support it needs by keeping it connected to the fuel tank. The last part that completes the assembly is the fuel gauge sender. This component provides additional support to ensure that all these parts stay in place no matter how rough the road gets. Because it plays an important role in providing your engine with fuel, the Fuel Pump Assembly is constructed using premium materials. This gives it the toughness it needs to withstand the ill effects of wear and tear, as well as exposure to various harsh elements. Each of its parts is given a direct-fit design, which ensures that they'll fit perfectly during setup. As a result, you can enjoy a quick and hassle-free installation. So, if you're after having consistent fuel flow throughout your engine, don't think twice about installing this assembly. Simply place an order here at Auto Parts Warehouse to get one that's right for your vehicle.

Questions to Ask When Choosing a Fuel Pump Assembly

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.

How to Do a Fuel Pump Assembly Test

Before you yank out that old fuel pump assembly and put a new one in, make sure that that’s what’s causing your car troubles. This means you have to check the entire assembly and related components by doing an electrical and pressure test. Here’s how:

Difficulty level: Easy

Tools you’ll need:

  • Voltmeter
  • Fuel pressure gauge

Electrical test:

Step 1: Inspect the fuse of the fuel pump. Locate the fuse box with the help of your vehicle manual. Then fine the fuse for the fuel pump. Check the fuse for signs of damage such as scorch marks. If the fuse is blown, check the relays to eliminate wire problems. Replace a blown fuse or a worn-out wire as soon as possible.

Step 2: Check the pump for voltage. A faulty pump assembly can actually be caused by a voltage shortage. So to make sure that enough electricity is going to the pump, check its voltage with a voltmeter. Connect the metering device onto the pump’s positive and negative terminals—make sure that the right probe is connected to the right terminal. Check the voltmeter’s screen for the reading. If the reading is lower or higher than the range indicated in your vehicle manual, then the pump has to be replaced.

Step 3: Check the pump wires. Do another drop test on the pump wires using the voltmeter. The process is similar: simply connect the voltmeter’s probes into the appropriate wires and check the readings. If the grounding wire is properly grounded and all the wires show the full voltage, then a faulty fuel pump is most likely the culprit behind your car problems.

Pressure test:

Step 1: Connect the pressure gauge to the pump fitting. The fitting is where the pump and the filter housing are joined together. This joint is where you will attach the pressure gauge. Since the location of the fuel pump and fitting depends on your car make and model, make sure to check your vehicle manual.

Step 2: Check the gauge. Let someone rev up the engine while you check on the gauge. Warm up the engine a bit. Then look at the pressure reading at idle speed and at a specific speed indicated in your pump specifications or vehicle manual. If the reading doesn’t match the specs indicated in the vehicle manual, you’ll have to install a new fuel pump assembly.
