What You'll Learn
Drain fuel from the tank
To drain the fuel from the tank of a 2007 Chevy Tahoe, you must first loosen the fuel filler cap to relieve the fuel tank's vapour pressure. Next, you need to raise and support the vehicle. You can refer to the manual for instructions on lifting and jacking the car.
Now, you can begin to drain the fuel. Loosen the fuel filler hose clamp and remove the hose from the tank. Insert a drain hose connected to a pump and container. Use the pump to drain the fuel from the tank into a suitable container. You can also use a hand or air-operated pump device to drain the fuel.
Alternatively, you can siphon the fuel out of the tank. Insert a tube into the tank and apply a little air pressure. The fuel will start flowing out and will continue until the tank is empty. You can also use a battery-operated pump to drain the fuel.
Please note that gasoline and gasoline vapours are highly flammable, so it is important to take safety precautions when draining fuel. Always have a dry chemical (Class B) fire extinguisher nearby. Never drain or store gasoline in an open container due to the risk of fire or explosion.

Disconnect the filler neck
Disconnecting the filler neck is a crucial step in removing the fuel tank of a 2007 Chevy Tahoe. It is important to proceed with caution when performing this task, as gasoline is highly flammable.
To begin disconnecting the filler neck, first, relieve the system fuel pressure at the Schrader valve, located on the fuel rail in the engine compartment. This step is important for safety reasons and should not be skipped.
Next, you will need to equalize the tank pressure by removing the fuel filler cap. This will ensure that there is no excess pressure built up in the tank, which could pose a safety hazard.
Once the pressure has been relieved and equalized, you can proceed with the physical disconnection of the filler neck. Raise and securely support the truck on jack stands to ensure stability.
Now, you can start to remove the fuel tank by first disconnecting the filler neck, along with the filler EVAP line and the fuel supply line. Be sure to follow the detailed instructions provided in Chapter 4, Section 5 of the Haynes manual for your vehicle.
After you have disconnected the filler neck and associated lines, carefully lower the fuel tank to access the remaining lines and electrical connections. This will allow you to complete the process of removing the fuel tank and perform any necessary maintenance or repairs.
It is important to note that working on the fuel system of a vehicle can be complex and potentially dangerous. Always refer to the manufacturer's instructions or seek the assistance of a qualified mechanic if you are unsure about any steps or procedures.

Disconnect the filler EVAP line
To disconnect the filler EVAP line in a 2007 Chevy Tahoe, you will need to locate the EVAP canister and identify the correct line to disconnect.
First, locate the EVAP canister, which is typically found near the fuel tank. The EVAP canister is a charcoal-coloured component with several hoses or lines connected to it. These lines include the EVAP vent line, which goes up towards the filler neck, and the EVAP purge valve line, which connects to the purge valve located in the engine compartment.
Once you have located the EVAP canister and identified the lines, you can proceed to disconnect the filler EVAP line. This line is typically identified by a picture of a gas pump on the line or hose itself. Before disconnecting, ensure that the fuel system is depressurized and that you are working in a well-ventilated area to avoid any safety hazards.
To disconnect the line, you may need to loosen or remove any clamps or fasteners securing the line in place. Use appropriate tools, such as wrenches or pliers, to carefully loosen these connections without damaging the lines or surrounding components. It is recommended to have a drip pan or container ready to catch any fuel or vapours that may escape during the disconnection process.
After disconnecting the line, you may want to inspect it for any blockages or restrictions. This can be done by blowing compressed air through the line, ensuring that it is clear of debris or obstructions. Additionally, you can check the line for any signs of damage, cracks, or leaks, as these may indicate the need for a replacement line.
It is important to note that working on the fuel system and EVAP components can be complex and requires caution. Always refer to the vehicle's service manual for specific instructions and safety precautions. If you are unsure or uncomfortable with any part of the process, it is recommended to seek assistance from a qualified mechanic.

Disconnect the fuel supply line
To disconnect the fuel supply line of a 2007 Chevy Tahoe, follow these steps:
Firstly, relieve the system fuel pressure at the Schrader valve on the fuel rail in the engine compartment. This is an important initial step to ensure safety and relieve pressure from the fuel lines. Next, equalize the tank pressure by removing the fuel filler cap. This will balance the pressure inside the fuel tank and make it safer to work on. Now, you need to raise the truck and support it securely on jack stands. This will allow you to access the underside of the vehicle and the fuel tank.
Once the vehicle is raised and supported, locate the fuel supply line. It is one of the lines connected to the charcoal canister, which is usually located near the spare tire. There should be three lines attached to the canister: one leading to the EVAP valve solenoid, one to the fuel tank (identified by a gas pump symbol), and one to the purge valve. Disconnect the line with the gas pump symbol, which is the fuel supply line. You may need to use appropriate tools, such as wrenches or pliers, to carefully loosen and detach the line. Ensure that you do not damage any nearby components or connections.
At this point, you have successfully disconnected the fuel supply line. However, it is important to note that working on a fuel system can be complex and dangerous. Always refer to a reliable repair manual or seek advice from a qualified mechanic if you are unsure about any steps or procedures. Additionally, gasoline and its vapors are highly flammable, so take extreme caution and follow safety guidelines to prevent fires or explosions.

Remove the fuel tank strap bolts
To remove the fuel tank strap bolts, you will first need to relieve the system's fuel pressure at the Schrader valve on the fuel rail in the engine compartment. Then, equalize the tank pressure by removing the fuel filler cap. Next, you will need to raise the truck and support it on jack stands.
Before removing the fuel tank strap bolts, you will need to disconnect the filler neck, filler EVAP line, and fuel supply line. You will also need to support the tank and loosen the bolts. Once the bolts are loose, you can lower the tank just enough to disconnect the electrical connections to the fuel pump and sending unit.
It is important to note that gasoline is extremely flammable, so take extra precautions when working on any part of the fuel system. Do not smoke or allow open flames or bare light bulbs near the work area. Make sure to mop up any spills immediately and do not store fuel-soaked rags where they could ignite.
It is also recommended to have a dry chemical (Class B) fire extinguisher nearby in case of a fire.
