Removing the tailgate, spare tire, and bed bolt

To remove the tailgate, spare tire, and bed bolt on your 1997 Dodge Ram 1500, follow these steps:

Removing the Tailgate:

First, locate the two side straps that support the tailgate. Tip the tailgate up far enough to release these straps, then lower it about a quarter of the way down. Now, slide the tailgate up and through the cutout on one side, and then to the side.

Removing the Spare Tire:

The tire-changing tools are located under the passenger seat. You will find a jack and a black leather bag containing the tools, including a lug wrench and about three extensions for dropping the spare tire. Go to the back of the truck and look at the top of the bumper, around the license plate area, between the bumper and the tailgate. You will find a square receptacle, about 1/2" square. Insert one or two of the extensions into this receptacle. The lug wrench has a square hole in its handle, which you will slide over the extension. Use the lug wrench to crank the tire down.

Removing the Bed Bolt:

Start by removing the bumper. Then, unhook the wiring and fuel hose. Loosen the bolts, and you may need to remove the tail lights and slide the wires down the holes. It is recommended to have three or four people to lift the bed and remove it. There are six bolts for a short bed and eight bolts for a long bed. Don't forget to remove the fuel filler bucket and the ground strap on the passenger side between the cab and the bed.

Disconnecting the taillights and license plate lights

Before beginning, ensure you have gathered the necessary tools and that your 97 Dodge Ram 1500 is parked on level ground, with the parking brake engaged for safety. This task will involve working underneath the vehicle, so ensure you have a clear and well-lit workspace.

To begin disconnecting the taillights and license plate lights:

  • Remove the tailgate of your 97 Dodge Ram 1500. This will provide access to the taillight wiring and license plate light wiring.
  • Locate the wiring harness for the taillights. It is usually positioned near the rear of the vehicle, connected to the taillight assembly.
  • Disconnect the taillight wiring harness: Carefully pull back the wiring cover to expose the wiring harness. You may need to remove any clips or fasteners securing the cover. Then, unplug the electrical connector by depressing the locking tab and gently pulling the connector apart. Ensure you do not force it, as this may damage the connector.
  • Remove the screws or fasteners holding the taillights in place. The number and location of these screws may vary depending on your vehicle, so refer to your owner's manual if needed.
  • With the taillights removed, you will have better access to the license plate light wiring.
  • Disconnect the license plate light wiring in a similar manner to the taillights. Carefully detach the wiring cover and unplug the electrical connector.
  • Remove the screws or fasteners holding the license plate lights in place, if applicable.

Once the taillights and license plate lights are disconnected and removed, set them aside safely. You should now have greater access to the fuel lines and the fuel pump. Remember to keep the wiring harnesses organized and protected to prevent any accidental damage during the fuel line installation process.

It is important to work carefully and methodically when performing these steps to avoid any damage to the lighting systems or their wiring. Always refer to your vehicle's repair manual for specific instructions pertaining to your 97 Dodge Ram 1500 model.

Disconnecting the wiring and ground wire connection

Firstly, remove the tailgate and spare tire from the vehicle. This will provide better access to the wiring and ground wire connection. It is also recommended to remove the tail lights at this stage, as mentioned by one source. This will ensure they do not hinder your access to the relevant components.

Once you have a clear view, locate the ground wire connection. On a 97 Dodge Ram 1500, this is usually found right behind the cab on the right side. Disconnect this ground wire, being careful to note its position for reassembly.

Next, you will need to disconnect the wiring. This process will involve detaching the connectors for the taillights and pulling the wiring out of the way. This step ensures that the wiring does not restrict your access to the fuel lines and pump.

It is important to work carefully and methodically when disconnecting the wiring and ground wire connection. Ensure that you have a clear understanding of the vehicle's electrical system before proceeding. If you are unsure, it is recommended to consult a professional or seek advice from a trusted mechanic.

By following these steps, you will successfully disconnect the wiring and ground wire connection, allowing you to access and work on the fuel lines and pump of your 97 Dodge Ram 1500. Remember to take your time and refer to vehicle-specific repair manuals or forums if you require further clarification on any steps.

Lifting the bed to access the fuel pump

Lifting the bed for access to the fuel pump is a common approach for the Dodge Ram 1500. This method is often considered easier than dropping the tank, especially when working with a full tank of fuel. Here is a step-by-step guide to lifting the bed to access the fuel pump:

Preparation:

Before starting, ensure you have the necessary tools and equipment, such as a jack or lift, jack stands, roller stands, or a couple of strong individuals to help lift the bed. Additionally, you will need tools to remove bolts and disconnect wiring. It is also recommended to run the fuel tank as low as possible before starting to reduce the weight and make the process safer and more manageable.

Step 1: Disconnect and Remove Necessary Components:

Start by disconnecting the taillights and pulling the wiring out of the way. Remove the screws holding the taillights in place, and don't forget to disconnect the license plate lights as well. If you have a spare tire underneath, you will need to drop it down.

Step 2: Lift the Bed:

With the necessary clearances and disconnects made, it's now time to lift the bed. This step typically requires two strong individuals or the use of a lift/jack. You don't need to remove the bed completely; instead, move it up and back about 2 feet to gain access to the top of the fuel tank. Be cautious not to lift it too high, as the lower front of the bed can make contact with the back of the cab.

Step 3: Access the Fuel Pump:

With the bed lifted and moved back, you now have access to the fuel pump. Before removing the fuel pump, it is essential to disconnect the fuel filler lines and the harness plug. The fuel line is pressurized, so exercise caution during this step.

Step 4: Clean and Prepare the Area:

Before installing the new fuel pump, it is good practice to clean the top of the tank and the surrounding area. Use a degreaser and a water hose to thoroughly clean any debris. You can then use a blow gun to remove any remaining water and loose debris.

Step 5: Install the New Fuel Pump:

Place the new fuel pump in the tank, ensuring that the fuel line port faces out to the driver's side. Secure the pump in place and reconnect the fuel line and power connections. Tug on the connections lightly to ensure they are locked in securely.

Step 6: Test the Pump and Reassemble:

Reconnect the battery and turn the key to the "ON" position to prime the pump. Repeat this process a few times to ensure the pump is functioning correctly. Once you've confirmed the pump is working, you can reverse the process by lowering the bed and making all the necessary connections and bolt fastenings.

Replacing the fuel pump and connecting the new one

To replace the fuel pump in a 1997 Dodge Ram 1500, you will need to first remove the tailgate, spare tire, and all but the right rear bed bolt. Disconnect the wiring, including the ground wire connection behind the cab on the right side. Lift the bed until you can reach the fuel pump.

The average national cost for a fuel pump replacement across all vehicles is between $611 and $894, including parts and labor. However, it is best to check with your local Dodge mechanic or dealership for a specific estimate.

When installing the new fuel pump, ensure that you have purchased a high-quality and reliable product, preferably an OEM factory fuel pump. Carefully inspect the old pump and take note of any adjustments that might be needed for the new one, such as the float level angle for the gas gauge to register correctly.

Prime the new pump by pushing in the schrader valve and turning the key several times. Test the pump by trying to start the engine. If the engine doesn't fire, you may need to repeat the priming process or check for any other issues.

For the fuel lines, you can use either silicone or rubber fuel lines rated for diesel fuel. Marine-grade diesel fuel line (rubber) or diesel fuel-rated hose is recommended. You will need two different sizes: 3/8" and 5/16" hose, with the smaller size for the return line.
