Walbro fuel pumps are designed to deliver speed, power, torque, and reliability. They are built to meet the demands of high-pressure and high-flow engines with efficient and durable performance. If you're looking to install a Walbro fuel pump in your Suburban, there are a few things to keep in mind. Firstly, you'll need to determine the specific model of your Suburban and choose a compatible Walbro fuel pump. The installation process will involve removing the old pump, placing a new rubber gasket on the Walbro pump, and reconnecting the fuel lines and wiring. It is recommended to jack up the car and disconnect the negative battery cable before beginning any work. Additionally, some soldering or crimping may be required for the wiring, and it's important to use compatible gas/E85 solder, wire, and connectors for in-tank connections.

Disconnect the negative battery cable and jack up the car
Disconnecting the negative battery cable and jacking up your car are important steps to take when installing a Walbro fuel pump in your Suburban. Here is a detailed guide on how to do this:
Disconnecting the Negative Battery Cable:
First, ensure your vehicle is powered down and the ignition is off. Then, pop the hood of your car to access the battery. Car batteries are typically located under the hood, but sometimes they can be found in the trunk, so consult your owner's manual if you're unsure.
Once you've located the battery, identify the negative terminal. It is usually marked by a '-' symbol and is typically black, often with a black plastic cap. The positive terminal, in contrast, is marked by a '+' sign and is usually red.
Now, remove any plastic caps from the battery terminals. Then, locate a wrench that fits the nuts and bolts of your battery terminals. There is no universal size, so you may need to try different wrench sizes. Place the wrench on the negative terminal's nut and turn it counterclockwise to loosen it.
After loosening the nut, remove the negative connector cable from the battery post. Ensure that the cable is moved aside and kept entirely out of the way, with no chance of it coming into contact with the battery again until you are ready.
Jacking Up the Car:
Now that the negative battery cable is disconnected, you can safely jack up your car. Use a jack to lift the car as high as you can safely manage. This will provide you with better access to the fuel pump and tank for the next steps of the installation process.
Remember to exercise caution when working on your vehicle. Wear eye protection and ensure that all tools are used correctly. It is also important to keep the disconnected cable secured and away from the battery terminals to avoid any accidental contact that could cause sparks or short circuits.

Remove the old pump and place a new gasket on the Walbro
Removing the old pump and installing a new fuel pump can be a tricky process, so it's important to be cautious and patient. First, disconnect the negative battery cable. Jack up the car to a safe height and disconnect the fuel line and wiring harness from the tank. Now, you can remove the locking ring to loosen the pump and take it out of the tank.
Next, you'll need to remove the nuts holding the wires to the top of the fuel pump. Small wrenches or pliers can be used for this step. Be cautious when removing the screw at the bottom of the assembly, as it may be stubborn. Once the screw is removed, you should be able to unclip the metal piece holding the pump in place.
Now, you can remove the old fuel pump. Take note of the direction that the filter sticks out from the assembly, as this will be important when installing the new pump. You can discard the old rubber fuel pump isolator, as the Walbro kit will supply a new one.
Finally, you're ready to place the new gasket on the Walbro. The Walbro kit should come with a new O-ring, so replace the old rubber O-ring in the fuel pump connection with the new one. Slide the spacer over the Walbro and push the new fuel filter into the assembly, ensuring it aligns with the bracket. Then, push the new rubber isolator onto the bottom of the pump and reattach the metal retainer to the pump and bracket, screwing it into place.

Reinstall the screw ring and tank, and reconnect the fuel line
Reinstalling the screw ring, tank, and fuel line is the reverse of the removal process. First, reinstall the screw ring that holds the assembly in the tank. Then, reinstall the tank, the fuel filler hose, the EVAP canister, the EVAP canister lines, and the wiring harness. Reconnect the fuel line and ensure that the far end of the pump (with the visible filter) seats into the new seal. Put the canister back together, reinstall the rubber wire grommet into the top of the canister, and reconnect the wires to the plug. Make sure to use gas/E85 compatible solder/wire/connectors for in-tank connections.
It is important to note that the process may vary slightly depending on the specific vehicle and fuel pump being installed. Always refer to the manufacturer's instructions and take the necessary safety precautions when performing any vehicle maintenance or repairs.

Check the pump filter and seal when putting the canister back together
When putting the canister back together, it is important to check the pump filter and seal. This is a crucial step to ensure the fuel pump functions correctly and there are no leaks.
First, check the pump filter. This is located at the far end of the pump and has a visible filter. Make sure that this seats correctly into the new seal—it may take a little aiming to get it right. Once the filter is in place, you can put the canister back together, and reinstall the rubber wire grommet into the top of the canister.
Next, reconnect the wires to the plug and install a new sediment filter. The canister is now ready to go back into the tank. Before doing so, install the new tank seal that comes with the Walbro pump. This will ensure a tight fit and prevent leaks.
Finally, reinstall the tank, the fuel filler hose, the EVAP canister, the EVAP canister lines, the fuel line, and the wiring harness. It is important to take your time with this step to ensure all connections are secure and correct.
By carefully checking the pump filter and seal when putting the canister back together, you can ensure the Walbro fuel pump functions optimally and safely.

Reinstall the EVAP canister, fuel filler hose, and wiring harness
To reinstall the EVAP canister, fuel filler hose, and wiring harness, you must first ensure that the far end of the pump (where the filter is visible) is seated correctly in the new seal. This requires a bit of aiming to get right. Once the canister is back together, reinstall the rubber wire grommet into the top of the canister, and reconnect the wires to the plug. Put on the new sediment filter and install the new tank seal that comes with the Walbro pump.
Now, the in-tank assembly is ready to go back into the tank. Reinstall the tank, followed by the fuel filler hose, the EVAP canister, the EVAP canister lines, and the fuel line. Finally, reinstall the wiring harness.
Before beginning the installation, ensure that you have crimped or soldered the connectors onto the stock wiring. Use gas/E85 compatible solder/wire/connectors for in-tank connections.
The stock style fuel pump is an in-tank electric fuel pump, so the installation should be straightforward. Simply twist the pump to lock it into place, then reinstall the screw ring that holds the assembly in the tank.
