What You'll Learn
Disconnecting the fuel pump
Firstly, ensure you discharge the fuel pressure. Disconnect the negative battery cable and enter the fuse block to remove the Circuit Opening Relay. Reconnect the cable and start the truck until it dies, turning the ignition switch back to 'ON'. Crank the truck to confirm no fuel pressure remains.
Remove the fuel tank cap and reinstall the Circuit Opening Relay. Disconnect the negative battery cable once more. If your Tacoma has the TRD off-road package, remove the skid plate covering the tank.
There are two fuel lines connected to the tank: the main line and the return line. Remove the clamp holding these lines together and separate the connection.
Remove the fuel pump cover and disconnect the fuel pump connector. Pinch the connector and pull out the fuel tank vent hose. Protect the connector with a plastic bag.
Finally, ensure everything is disconnected from the tank before lowering it.
It is important to note that you can drain the fuel tank without removing it. This can be done by running the fuel pump until the tank is empty, then refilling it with gas. Alternatively, you can connect the fuel pump to an alternative 12v source and pump out the fuel.

Removing the fuel tank bands
To remove the fuel tank bands of a 2006 Tacoma, you must first remove the two bolts on one side of the bands. Then, remove the clip and pin on the other side of the bands. When removing the bolts, clips, and pins, it is important to be careful and not force anything, as this can cause damage. Once these are removed, slightly lower the tank to remove the fuel filler neck, being careful not to lower it too far to avoid breaking or stretching the wires.
After this, remove the fuel pump cover and disconnect the fuel pump connector. There should be one more tube coming out of the tank, the fuel tank vent hose, and there should be another connector for it on or near the charcoal canister. Pinch the connector together and pull the tube out, protecting the connector with a plastic bag. Make sure everything is disconnected from the tank before dropping it down all the way.

Discharging the fuel pressure
To disconnect the fuel lines at the gas tank of a 2006 Tacoma, you must first discharge the fuel pressure. Here is a step-by-step guide on how to do this:
Firstly, disconnect the negative battery cable and go into the fuse block next to the battery. Remove the Circuit Opening Relay. Then, reconnect the negative battery cable and start the truck. Crank the engine until it dies, but make sure to turn the ignition switch back to the 'ON' position. You may see a 'Check Engine' light come on, but this can be reset for free at auto parts stores. Crank the truck again to ensure there is no fuel pressure left.
Next, remove the fuel tank cap and reinstall the Circuit Opening Relay. Disconnect the negative battery cable once more. If your Tacoma has the TRD off-road package, you must remove the skid plate that covers the tank. There are two fuel lines that go to the tank: the main line and the return line. Remove the clamp that holds these lines together.
Now, you can begin to disconnect the fuel lines. Pinch the sides of the connectors and pull the lines apart. Be sure not to use any tools for this step, as you do not want to damage the connectors. Cover the connectors with plastic bags to protect them from dirt and contaminants.
At this point, you can start to lower the tank. First, remove the two bolts on one side of the fuel tank bands, then remove the clip and pin on the other side. Lower the tank slightly to remove the fuel filler neck, being careful not to lower it too far to avoid breaking or stretching the wires.
Finally, remove the fuel pump cover and disconnect the fuel pump connector. There should be one more tube coming out of the tank, the fuel tank vent hose, with another connector on or near the charcoal canister. Pinch this connector together and pull the tube out, protecting it with a plastic bag. Ensure everything is disconnected before lowering the tank completely.
It is important to note that some sources suggest an alternative method for draining the fuel tank without removing it. This involves running the fuel pump until all the fuel is out, then refilling with gas and starting the engine. However, this method may cause the engine to run poorly initially.

Disconnecting the fuel line
Firstly, safety is paramount when working with fuel systems. Ensure you are in a well-ventilated area and take the necessary precautions to avoid any sparks or open flames. Discharge the fuel pressure by disconnecting the negative battery cable and removing the Circuit Opening Relay from the fuse block. Reconnect the cable, start the truck, and let it run until it dies. Crank the truck to ensure no fuel pressure remains.
Next, remove the fuel tank cap and reinstall the Circuit Opening Relay. Disconnect the negative battery cable again. If your Tacoma has the TRD off-road package, remove the skid plate covering the tank. There are two fuel lines: the main line and the return line. Remove the clamp holding them together, and separate the connection at the clamp.
Now, we will focus on the various tubes and connectors. There should be two tubes running up the filler neck. Loosen the hose clamp around the fill tube and remove the breather tube. Disconnect the connector on the third tube and protect it with a plastic bag.
Remove the fuel pump cover and disconnect the fuel pump connector. There is one more tube, the fuel tank vent hose, with a connector on or near the charcoal canister. Pinch the connector and pull out the tube, protecting it with a plastic bag. Ensure all connections to the tank are disconnected before lowering the tank.
Finally, support the tank and slightly lower it to remove the fuel filler neck, being careful not to stretch or break the wires.
It is important to note that disconnecting fuel lines is generally not recommended unless you are replacing or performing maintenance on a specific component. Whenever in doubt, consult a qualified mechanic or refer to the repair manual for your vehicle.
