Replacing The Fuel Tank In A '95 Chevy Diesel Truck

Changing the fuel tank in a 1995 Chevy diesel vehicle is a complex process. It is important to note that the fuel tank should be removed only if necessary, as it is a challenging task that requires careful attention to safety. Before beginning, ensure the vehicle is raised and securely supported with jack stands. The process involves disconnecting the negative battery cable, draining the tank, removing the filler neck clamp and vent tube hose, and carefully detaching support straps, insulators, and, if present, the gauge hose and fuel tank shield. Lowering the tank grants access to the gauge wiring, electrical connections, and hoses, which must be carefully detached before removing the tank entirely. Installation of a new tank involves reversing these steps, ensuring secure connections and checking for leaks.

Disconnect the negative battery cable

To disconnect the negative battery cable, you will need to locate the battery in your 1995 Chevy diesel. The battery is typically located in the engine bay, near the firewall, on the driver's side of the vehicle. Once you have located the battery, follow these steps:

Step 1: Put on safety gloves and goggles to protect your hands and eyes from any acid or debris.

Step 2: Identify the negative battery cable. It should be marked with a "-" symbol or a black cover.

Step 3: Loosen the nut or bolt that secures the cable to the battery terminal using a wrench or socket. Do not allow the wrench or socket to touch any other metal parts of the car, as this could cause a short circuit.

Step 4: Remove the cable from the terminal and place it to the side, ensuring it does not touch any metal surfaces.

Step 5: Secure the cable to prevent accidental contact with the battery terminal. You can use electrical tape or a cable tie for this.

At this point, the negative battery cable should be successfully disconnected. Remember to reconnect it once you have completed the fuel tank replacement by simply reversing the steps outlined above.

Drain the tank

To drain the tank of your 1995 Chevy, you'll need to first disconnect the negative battery cable. This will ensure that no power is being supplied to the fuel system. Next, raise the rear of your vehicle and support it with jack stands. This will allow you to access the underside of the vehicle and the fuel tank.

Once the vehicle is securely raised, locate the clamp on the filler neck and the vent tube hose. Remove the clamp, as well as the vent tube hose. If your vehicle is equipped with a gauge hose attached to the frame, remove this as well.

At this point, you will need to support the tank securely while removing the support straps and insulators. If your Chevy has a fuel tank shield, remove this as well.

With the support straps and insulators removed, you can now lower the tank. As you lower the tank, be sure to carefully manage the gauge wiring, electrical connections, and all hoses connected to the tank. Continue lowering the tank until you have enough clearance to access and disconnect these components.

Once the tank is lowered, you can proceed to remove the various hoses, electrical connections, and wiring. This will complete the draining process, and you can now remove the fuel tank entirely if needed for further maintenance or replacement.

Remember to exercise extreme caution when working with fuel systems, and ensure that you are in a well-ventilated area to prevent the buildup of flammable fumes. It is also recommended to have at least one helper to assist in manoeuvring and supporting the tank during the process.

Remove the filler neck and vent tube hose

To remove the filler neck and vent tube hose, you will need to first disconnect the negative battery cable. Next, drain the tank and raise the rear of your vehicle, supporting it with jack stands. Remove the clamp on the filler neck and vent tube hose. If your vehicle has a gauge hose attached to the frame, remove this too.

It is important to note that the process of removing the filler neck and vent tube hose is part of the broader process of removing the fuel tank. This is a complex task that requires careful attention to safety precautions. It is always recommended to consult a certified mechanic or a professional service manual for guidance on such tasks.

Remove the gauge hose

To remove the gauge hose from a 1995 Chevy diesel fuel tank, you must first disconnect the negative battery cable. Next, drain the tank and raise the rear of the vehicle, supporting it with jack stands.

Remove the clamp on the filler neck and the vent tube hose. If your vehicle is equipped with a gauge hose, you will need to remove it from the frame. This is the gauge hose removal step.

Now, while supporting the tank securely, remove the support straps and insulators. If your Chevy has a fuel tank shield, remove this too.

Lower the tank until the gauge wiring, electrical connections, and all hoses can be removed.

This is the process of removing the gauge hose when changing the fuel tank on a 1995 Chevy diesel.

Remove the support straps and insulators

To remove the support straps and insulators, you will need to raise the rear of your vehicle and support it with jack stands. Once the vehicle is securely raised, you can begin the process of removing the support straps and insulators.

First, locate the support straps and insulators. These are typically found near the fuel tank, as they are responsible for providing support and stability to the tank. Make sure to identify all the components that need to be removed before beginning the removal process.

Next, securely support the fuel tank. This step is crucial as you don't want the tank to shift or move during the removal process. Use appropriate tools and stands to ensure the tank is held firmly in place. With the tank securely supported, you can now start removing the support straps.

Carefully remove the support straps, being mindful of any electrical connections or hoses that may be attached to them. Depending on your vehicle's configuration, you may also need to remove mounting bolts or other fasteners that secure the straps in place. Work slowly and methodically to avoid damaging any surrounding components.

After removing the support straps, you can proceed to remove the insulators. Insulators are typically used to reduce vibration and noise, and they may be attached to the support straps or located nearby. Again, pay close attention to any attached wires or hoses, and carefully detach them as necessary. Ensure that you have all the necessary tools for this process, such as wrenches or screwdrivers, to avoid any delays or complications.

Finally, once all the support straps and insulators have been removed, carefully lower the fuel tank slightly for easier access to the remaining connections. It is important to work slowly and cautiously throughout this entire process to avoid any damage to the vehicle or injury to yourself.
