What You'll Learn
Drain the fuel tank
To drain the fuel tank of a Chevy S10, you must first disconnect the fuel lines. It is recommended to draw a picture or label the lines so that you remember where they go. Then, connect a short length of hose to the outlet side of the pump, which will be the line closest to the cab. Run the other end of the line into a gas can.
Next, disconnect the wiring harness that goes to the fuel pump. You can then use a jumper wire to connect one end to the positive terminal on your battery and touch the other end to one of the leads in the plug on the fuel pump, which will pump out the remaining gas.
If your tank is full, it will be more challenging to remove and drain. In this case, you may be able to remove the pump and sender unit to try and siphon out most of the fuel. You can then change the filter and look at draining the tank.
It is also important to note that removing the truck bed first can make the process of draining the fuel tank and accessing the fuel lines much easier.

Disconnect the fuel lines
Disconnecting the fuel lines of your Chevy S10 is a crucial step in removing the fuel tank. Here is a detailed guide to help you through the process:
Firstly, ensure you have drained the fuel tank. This is important for safety reasons and to avoid spills. If your tank is full, you will need to pump out the gas. One method is to connect a short length of hose to the outlet side of the pump, which is the line closest to the cab. Run the other end of the hose into a gas canister. You can then use a jumper wire to connect one end to the positive terminal on your battery and touch the other end to the fuel pump to pump out the gas.
Next, you will need to gain access to the fuel lines. This may involve removing the truck bed, which is easier than trying to access the lines with the bed in place. Remove the bolts from the bed of the truck, disconnect the wires from the taillights, and disconnect the filler neck at the gas cap door. With the bed removed, you will have better access to the fuel lines.
Now, you can start to disconnect the fuel lines. It is important to work carefully and methodically to avoid any damage. Label the lines clearly so that you know exactly where they need to be reconnected. Loosen the filler neck hose clamp at the fuel tank and then disconnect the fuel tank filler neck from the fuel tank. You may need to remove the fuel tank shield for better access.
Finally, with the fuel lines disconnected, you can proceed to remove the fuel tank or perform any necessary maintenance. Remember to support the tank as you work, using jack stands or a similar method, to prevent it from dropping unexpectedly. Always refer to a repair manual or seek expert advice if you are unsure about any steps in the process.

Remove the fuel pump
To remove the fuel pump from a Chevy S10, you will first need to drain the fuel tank. This can be done by disconnecting the fuel lines and connecting a short length of hose to the outlet side of the pump. Run the other end of the line into a gas can and use a jumper wire to connect one end to the positive terminal on your battery. Touch the other end to one of the leads in the plug on the fuel pump, and this will pump out the gas.
Once the tank is drained, you can drop it and pull the fuel pump out of the top. It is easier to remove the truck bed than to remove the tank, so you may want to do this to give yourself more room to work. To remove the bed, disconnect the wires from the tail lights and the filler neck at the gas cap door. You will need to remove 8 bolts from the bed of the truck. Then, call a friend to help you lift the bed and sit it on the rear wheels.
Now you have access to the fuel pump and can remove it without dropping the tank.

Clean the fuel supply
To clean the fuel supply of your Chevy S10, you must first drain the fuel tank. This can be done by disconnecting the fuel lines and allowing the fuel to empty into a gas can. It is important to label the fuel lines before disconnecting them so that you can remember where they go when reassembling.
Once the fuel tank is drained, you can remove it by following these steps:
- Raise and support the vehicle.
- Remove the straps from the tank.
- Lower the tank slightly.
- Remove the wiring and fuel lines from the tank.
- Carefully inspect the wiring for any signs of damage, such as animal nests or chewed-up wires.
With the fuel tank removed, you can now clean the fuel supply. This involves blowing air through the fuel supply at the engine to ensure that there are no blockages in the fuel line. You should also inspect the fuel filter and replace it if necessary.
If you are experiencing issues with the fuel injectors, it may be necessary to clean or replace them. This can involve priming the throttle body, checking for spark and injector pulse, and replacing the injector if necessary.
It is also important to check for any leaks in the fuel system, such as at the vapor canister or gas cap, and to address them accordingly.
Finally, when reassembling the fuel tank and supply, ensure that all connections are secure and that there are no leaks.

Replace the fuel tank
To replace the fuel tank of a Chevy S10, you will first need to drain the fuel tank. Disconnect the fuel lines and the wiring harness that goes to the fuel pump. You can then siphon out the fuel.
It is also recommended to remove the truck bed for easier access to the fuel tank. This can be done by two or three people. Disconnect the two plugs and three quick-connect fuel lines, and remove the six bolts and a wire harness for the tail lights.
Once the fuel tank is exposed, you can remove the straps holding the tank in place and lower it down. Remove the remaining wiring and fuel lines from the tank.
When installing a new fuel tank, ensure that you grease the lock ring to prevent rust. You will also need to get a new fuel sending unit lock ring or cam.
