Changing Diesel Fuel Filter In '95 Dodge Ram 2500: Step-By-Step Guide

Changing the fuel filter on a 1995 Dodge Ram 2500 diesel truck is a relatively simple task that can be completed in about an hour. The fuel filter is located under the vehicle, on the driver's side, below the seating area, and mounted on the frame rail in the fuel line. It is important to note that the fuel filter is part of the fuel pump assembly, which is located inside the fuel tank. To replace the fuel filter, you will need some sockets to unscrew the filter housing.

The fuel filter is part of the fuel pump assembly inside the fuel tank

To change the fuel filter on a 1995 Dodge Ram 2500 diesel, you'll first need to locate the fuel filter, which is part of the fuel pump assembly inside the fuel tank. This means that to access and replace the fuel filter, you'll need to remove the fuel tank from the vehicle. Here's a step-by-step guide to help you through the process:

Step 1: Prepare the Vehicle

• Park the vehicle on a level surface and engage the emergency brake.
• If needed, place wheel chocks in front of the front wheels and raise the rear of the vehicle with a floor jack.
• Place jack stands on each side of the vehicle against the frame rails. You can use blocks of wood to reduce potential damage from the sharp areas of the jack stands.

Step 2: Disconnect the Battery and Siphon Fuel

• Disconnect the negative (black) battery cable using a 10mm wrench. Move it away from the battery to avoid accidental contact.
• Use a suitable siphon pump to remove excess fuel from the tank. The fuel tank can weigh over 200 pounds when full, making it challenging to remove.

Step 3: Relieve Fuel Pressure

• Locate and remove the fuel pump fuse. You may find a diagram on the top or bottom of the under-hood fuse box cover.
• Once the fuse is removed, start the engine and wait for it to stall on its own.
• If the fuel pump is not functioning, locate the pressure relief valve on the fuel rail. You can push the small valve in with a screwdriver or attach a fuel pressure gauge with a drain hose. Be cautious when using the screwdriver method, as fuel will spray out.

Step 4: Loosen Fuel Tank Straps and Remove Skid Plates

• Loosen the fuel tank straps using a 15mm socket, but do not completely remove them yet.
• Remove the skid plates at the front and side of the fuel tank.

Step 5: Disconnect Fuel Filler Neck

• Open the fuel door and remove the Phillips head screws surrounding the filler hose opening.
• Loosen the fuel filler hose and vent hose clamps near the filler neck.
• Pull the hoses away from the fuel filler neck.

Step 6: Disconnect Electrical Connector and Fuel Pressure Hose

• Lower the fuel tank carefully, creating enough space to access the connections.
• Disconnect the electrical connector by pushing on the red locking tab and squeezing the flexible tab on the connector plug. Pull the connector plug away from the fuel pump.
• To remove the fuel pressure hose, squeeze the sides of the plastic quick disconnect fitting and pull the hose away from the fuel pump.
• Double-check that there are no other connections to the tank before lowering it completely.

Step 7: Remove and Replace the Fuel Pump Assembly

• You will see a plastic lock ring surrounding the fuel pump assembly. You can remove it with a strap wrench-type tool or a screwdriver/punch and a hammer.
• Use a screwdriver to gently pry the fuel pump assembly away from the rubber O-ring, and then lift the fuel pump out of the tank.
• Before installing the new fuel pump, transfer any necessary parts from the old assembly to the new one, following the manufacturer's instructions.
• Install a new rubber O-ring onto the tank, ensuring it remains level and in place during the new pump installation.
• Position the new fuel pump at an angle to first insert the sending unit's float, then press the fuel pump down onto the O-ring.
• Tighten the plastic lock ring.

Step 8: Reinstall the Fuel Tank and Reconnect Hoses

• Raise the fuel tank and begin to tighten the fuel tank straps.
• Ensure there is enough space between the tank and the vehicle to reconnect the electrical connector and the fuel pressure hose to the fuel pump.
• Continue raising the fuel tank until you can reconnect the fuel filler hose and vent hose.
• Attach the fuel filler neck to the body of the vehicle.
• Slide the skid plates back into place and tighten the tank down with the straps.

Step 9: Final Checks

• Reconnect the negative battery cable and install the fuel pump fuse.
• Turn on the ignition and inspect the fuel tank and connections for any signs of leaking fuel.
• If you notice any fuel leaks, clean the area and tighten the fuel pump lock ring. If the leak persists, the rubber O-ring may need to be replaced.

The filter is located under the vehicle, on the driver's side

To change the fuel filter on a 1995 Dodge Ram 2500 diesel, you'll first need to locate the filter, which is situated under the vehicle on the driver's side, below the seating area. This is on the driver's side of the transmission and is mounted on the frame rail in the fuel line.

Now, to change the filter, you'll need to get under the vehicle and locate the fuel lines that run to the filter. Once you've found them, carefully loosen the clamps that hold the fuel lines in place and slide them off the filter. Then, you can remove the old filter and replace it with a new one. Make sure to slide the fuel lines back onto the new filter and tighten the clamps securely.

It's important to be cautious when working with fuel lines to avoid any spills or leaks. Ensure you have adequate knowledge and experience before attempting this task. If you're unsure, it's best to consult a professional mechanic.

Additionally, it's worth noting that some sources suggest that the fuel filter on this model is part of the fuel pump assembly, located inside the fuel tank. This would mean dropping the fuel tank to access and replace the filter.

It is mounted on the frame rail in the fuel line

The fuel filter on your 1995 Dodge Ram 2500 diesel is located under the vehicle, on the driver's side, below the seating area. More specifically, it is mounted on the frame rail in the fuel line. This means it is a frame-mounted filter.

To change the fuel filter, you will need some sockets to unscrew the filter housing. You can refer to videos online for a visual guide to changing the filter.

There are two filters: one engine-mounted, and one frame-mounted

To change the fuel filter on a 1995 Dodge Ram 2500 diesel, you'll need to locate the two filters: one engine-mounted, and one frame-mounted. The engine-mounted filter can be found on the left side of the engine, while the frame-mounted filter is located under the vehicle, on the driver's side, below the seating area, and mounted on the frame rail in the fuel line.

Changing the fuel filters on this vehicle is a fairly simple process and can be completed in around an hour. You'll need some basic tools like sockets or wrenches to unscrew the filter housing and remove the old filters. It's recommended to have the part numbers for the new filters ready: DF99569 for the frame-mounted filter and DF99579 for the engine-mounted filter.

Before starting the replacement, it's important to relieve the fuel pressure in the system. Here are the steps to do so:

• Loosen the gas cap to release tank pressure.
• Remove the injector wiring harness connector from the engine harness.
• Connect a jumper wire between ground terminal No. 1 of the injector harness and the engine ground.
• Connect another jumper wire to the second terminal and touch the battery positive post for no longer than five seconds.
• Remove the jumper wires and proceed with the fuel filter replacement.

Once the pressure is relieved, you can proceed to replace the filters. Here are the general steps:

• Locate the filters as described above.
• Unscrew the filter housing using the appropriate socket or wrench.
• Remove the old filters and dispose of them properly.
• Install the new filters, ensuring they are securely connected to the fuel lines.
• Reattach the filter housing and tighten it with the tool.
• Check for any fuel leaks and ensure that all connections are secure.

It is important to note that working with fuel and vehicle repairs can be dangerous. Always exercise caution and refer to a professional mechanic if you are unsure about any part of the process. Additionally, having a second person to assist you can be helpful.
