Tips For Installing Fuel Lines
To help you get started, we offer fuel line installation instructions for GMC trucks and this video on installing fuel lines. The Yukon shares the same platform with other Chevrolet and GMC full-size trucks, like the Chevy Tahoe, Suburban, and Avalanche, so the steps are essentially the same for all vehicles.
Here are some other helpful tips to get started:
- •This video shows how to install a nylon line splice kit and reuse the original fittings.
- •These links will take you to videos showing the removal of a shipping twist and a shipping bend.
Additionally, you'll want to consider the following to make the job easier and safer:
- •Wear old clothes, nitrile gloves, and safety goggles for protection.
- •Be certain to work in a well-ventilated area so gasoline fumes don't build up. They are bad for your health and can also be flammable.
- •Keep a fire extinguisher handy because you're working around flammable liquids and vapors.
Steps For Replacing Fuel Lines On A GMC Yukon
Preparing To Disconnect The Fuel Lines
- Before disconnecting the fuel lines, you'll need to relieve the fuel pressure. Otherwise, any pressurized fuel will spray all over you and your vehicle.
- •Start by locating and removing the fuse or relay for your GMC Yukon's fuel pump.
- •Then try starting the truck. If it won't start or shuts off after a few seconds, you've depressurized the fuel lines.
- Disconnect the battery by removing the negative battery cable.
- Lift the vehicle using a jack and secure it with jack stands.
- Locate the existing fuel lines and fuel line connectors.
Disconnecting The Old Fuel Lines
Start by placing a bucket or drain pan under the fuel line before disconnecting it. Then, using the appropriate wrench or fuel line disconnect tool, loosen the fittings and remove any clamps or brackets securing the fuel lines to the vehicle's frame.
While replacing the fuel lines, it's also a good idea to replace the fuel filter, which may have become partially clogged with dirt or other contaminants.
Installing The New Fuel Lines
The first step is to use the GMC fuel line instruction diagrams to ensure the new fuel lines match the specifications and size of the original lines.
Once you've confirmed everything matches up, install the new fuel lines and tighten the clamps and connectors. Then reconnect the battery, reinstall the fuel pump fuse, and turn the vehicle's ignition to the "ON" position without starting the engine. This will pressurize the system, allowing you to check for leaks.
If no leaks are detected with the fuel system pressurized, start the vehicle and do a final check for leaks while running.
