Disconnect the negative battery cable and drain the fuel tank
Disconnecting the negative battery cable and draining the fuel tank are crucial steps in removing the fuel tank from a 97 Dodge 1500. Here is a detailed guide on how to safely and effectively complete these steps:
Disconnecting the Negative Battery Cable:
- Before beginning, ensure the ignition and start switch are in the OFF or LOCK position, and all electrical loads are turned off.
- Locate the negative battery cable. It is typically black and connected to the negative terminal of the battery, which is usually marked with a '-' sign or the word "NEG".
- Disconnect the negative battery cable first. Loosen the nut or bolt securing the cable to the terminal using an appropriate-sized wrench or socket. Be careful not to let the negative cable touch any metal surfaces or the positive terminal to avoid short circuits.
- Once disconnected, move the cable end away from the battery and insulate it by wrapping it in a non-conductive material, such as a towel or electrical tape.
Draining the Fuel Tank:
- Before draining the fuel tank, it is essential to release the fuel system pressure. Refer to your vehicle's manual or a mechanic for specific instructions on how to do this safely.
- Raise the vehicle to gain access to the fuel tank. Ensure the vehicle is securely supported on jack stands or ramps.
- Clean the area around the fuel fill fitting and rubber fuel fill hose at the tank to prevent any dirt or debris from entering the tank during the draining process.
- Loosen the clamp securing the rubber fuel fill hose to the tank fitting. Use a suitable tool, such as a screwdriver or wrench, to loosen the clamp without damaging the hose.
- Place an approved gas holding tank or container below the fuel tank to catch the drained fuel.
- Disconnect the rubber fuel fill hose from the tank fitting. Be cautious as fuel may start draining immediately. Ensure the drained fuel is collected safely in the holding tank.
- If your vehicle has an anti-theft/one-way valve, you may need to use your fingers to feel for it and properly position the fuel recovery tank hose.
- If necessary, you can use a siphon or jump the fuse for the fuel pump to aid in draining the tank. Always use approved fuel containers and take appropriate safety measures to prevent fuel spills or ignition.
Remember, working with fuel and electrical systems can be dangerous. Always refer to your vehicle's manual or seek professional guidance if you are unsure about any steps or procedures.

Loosen the filler neck hose clamp and disconnect the fuel tank filler neck
To loosen the filler neck hose clamp and disconnect the fuel tank filler neck, you must first ensure the ignition and start switch are in the OFF or LOCK position, and all electrical loads are OFF. Disconnect the negative battery cable to prevent an electrical spark.
Now, to loosen the filler neck hose clamp: First, raise the vehicle. Loosen the clamp, which is located at the fuel tank filler neck. Once loosened, you can disconnect the fuel tank filler neck from the fuel tank.
It is important to note that the fuel tank support fasteners should never be reused. Always use new fasteners when installing the fuel tank.
If you are having trouble removing the clamp, it may be beneficial to clean the connection with a brake cleaner spray or a similar product. This will also help to temporarily lubricate the connection. While pressing the retainer, push in on the fuel line as if you are trying to reattach it, and then pull out.
As a safety precaution, it is important to remember that the ball inside the fuel tank is an anti-siphon ball. Its purpose is to block off the fuel neck to prevent siphoning gas and spillage during a rollover. Do not remove this unless you are certain it is required.

Remove the tank straps and insulator strips
To remove the tank straps and insulator strips of a 97 Dodge 1500 fuel tank, follow these steps:
First, ensure the ignition and start switch are in the OFF or LOCK position, and all electrical loads are turned off. Disconnect the negative battery cable to prevent any electrical sparks. Next, drain the fuel from the tank. Refer to the Fuel Tank Draining Procedure for your specific vehicle. Once the tank is drained, raise the vehicle.
Now, you can begin to remove the tank straps and insulator strips. Loosen the filler neck hose clamp at the fuel tank. Support the weight of the fuel tank and remove the tank straps and insulator strips. Be cautious and take your time during this step to avoid any damage or injury. Ensure you have a secure grip on the tank and that it is safely supported throughout the process.
After removing the straps and strips, you can continue with the next steps, which include removing the frame-mounted bracket, lowering the fuel tank shield, and disconnecting the fuel feed and vapor hoses. Remember to refer to a qualified mechanic or a repair manual for specific instructions for your vehicle, as there may be additional considerations or variations in the procedure.

Lower the fuel tank shield and disconnect the fuel feed and vapor hoses
To remove the fuel tank from a 97 Dodge 1500, there are several steps you must follow to ensure your safety and complete the task effectively.
Firstly, the ignition and start switch must be turned off, and all electrical loads must be switched off before servicing any electrical components. It is also important to disconnect the negative battery cable to prevent an electrical spark, which may cause injury or damage to the vehicle.
Next, drain the fuel from the tank and raise the vehicle. Loosen the filler neck hose clamp and disconnect the fuel tank filler neck from the fuel tank. Support the fuel tank and remove the tank straps and insulator strips, if your vehicle is equipped with these.
Now, you can lower the fuel tank shield. At this stage, you should also lower the fuel tank. Once the tank is lowered, you can disconnect the fuel feed and vapor hoses.
It is important to note that when removing or replacing the fuel tank, the fuel tank support fasteners should never be reused. Always use new fasteners when installing the fuel tank.
In addition, the fuel tank brackets should be installed with insulator strips in place. Failure to tighten the strap fasteners as specified will cause the bottom of the tank to flex upward, resulting in an inaccurate fuel gauge reading.
Finally, when refilling the tank, ensure the fuel pressure is correct. For a 97 Dodge Ram 1500, the fuel pressure at idle should be around 49.2 psi, with a possible variation of +/- 5 psi. If the pressure drops below 44.2 psi during a load test, this indicates a failing fuel pump.

Reinstalling the fuel tank: use new fasteners and tighten to 33 N·m
When reinstalling the fuel tank, it is important to use new fasteners. Old fasteners should never be reused. The new fasteners should be tightened to 33 N·m (45 lb-ft).
It is important to tighten the strap fasteners by steps, alternating between the fasteners until the specified torque is reached. This is to avoid damage to parts and systems. The correct tightening sequence and specifications must be followed.
Additionally, replacement fasteners must be the correct part number for the application. Fasteners requiring replacement or the use of thread locking compound or sealant are identified in the service procedure.
Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings will affect fastener torque and joint clamping force and may damage the fastener.
