You’ll need a fuel line disconnect tool (you can usually find these at any auto parts store), a drain pan to catch any leftover fuel, some rags or shop towels, eye protection, and gloves. Trust me, you don’t want gasoline on your hands. It’s not only smelly, but it can also irritate your skin.
Location, Location, Location
Find a well-ventilated area to work in, preferably outdoors. Gasoline fumes are not something you want to breathe in. Also, make sure the area is free of any potential ignition sources, like open flames or sparks. Even a lit cigarette can be dangerous. Safety first, always!
Relieving Fuel Pressure
Before disconnecting the fuel line, it’s essential to relieve the pressure in the system. This prevents fuel from spraying everywhere when you disconnect the line. Locate the fuel pump fuse or relay (check your owner’s manual for its exact location) and remove it. Then, start the car and let it run until it stalls. This will burn off the remaining fuel pressure in the lines.
Double-Checking
Once the car stalls, try starting it again to ensure the pressure is completely relieved. If it doesn’t start, you’re good to go. If it does sputter or start, repeat the process until it doesn’t.
Disconnecting the Line - The Main Event
Now comes the actual disconnection. First, locate the fuel line connection point on the gas tank. It usually looks like a quick-connect fitting. Position your drain pan beneath the connection to catch any dripping fuel. Next, put on your eye protection and gloves – this is where things can get a bit messy.
Take your fuel line disconnect tool and carefully slide it onto the fuel line, pushing it towards the connector. You should feel it click into place. The tool is designed to depress the retaining clips within the connector, allowing you to separate the fuel line. Gently pull the fuel line away from the connector. It might require a little bit of force, but don’t yank on it too hard. If it’s really stuck, try wiggling the line gently while pulling.
Once the line is disconnected, a small amount of fuel might drip out. This is normal. Let it drain completely into the drain pan. You can use a rag or shop towel to wipe up any spills. Once the dripping stops, carefully inspect the disconnected fuel line and the connector on the tank for any damage. If everything looks good, you’re ready to move on to the next step in cleaning your gas tank.
Here’s a quick overview of the tools and their purpose:
