Changing The Fuel Filter In Your Ram 2500: Step-By-Step Guide

Changing the fuel filter on a RAM 2500 truck is a simple task that can be done at home with some basic tools and knowledge. The process involves locating and unscrewing the filter housing, replacing the old filter with a new one, and ensuring proper seating of the new filter. While it may seem daunting to those unfamiliar with fuel systems, online resources such as YouTube videos and forums provide detailed instructions and tips for a successful fuel filter replacement. It is important to use genuine or recommended fuel filters to ensure the truck's optimal performance.

Tools required: 28mm or 29mm socket, ratchet, extensions, and a swivel attachment

Changing the fuel filter on a RAM 2500 truck is a straightforward task that can be accomplished with a few basic tools. Here's a detailed guide on the tools required for the job:

28mm or 29mm Socket:

The fuel filter cap on a RAM 2500 is typically removed using a 28mm or 29mm socket. Some older models may use a 1-1/8" socket, but the 28mm or 29mm size is more common and provides a better fit. Make sure to get a 6-point socket for a secure grip. This socket size is required to fit the square receptacle on the fuel filter lid and facilitate its removal.

Ratchet:

A ratchet, preferably with a 1/2" drive, is used in conjunction with the socket to loosen and tighten the fuel filter lid. Ensure the ratchet has a square drive that fits securely into the socket. A swivel attachment can also be used with the ratchet to provide more flexibility in tight spaces.

Extensions:

Extensions are essential for reaching the fuel filter, which is located on the driver's side of the engine, near the firewall. A 12-inch or longer extension will provide the necessary reach. Additionally, a short extension can be useful when removing the filter element/lid to create more clearance.

Swivel Attachment:

The swivel attachment is an optional but useful accessory. It attaches to the ratchet and provides additional maneuverability in tight spaces. This can be helpful when accessing the fuel filter cap, especially if there are obstructions or limited clearance.

When gathering your tools, it's important to ensure they are the correct size and fit securely together. Working on fuel systems can be messy, so it's recommended to have some rags or a drain pan nearby to catch any spilled fuel. Always exercise caution when working with fuel, and refer to a qualified mechanic if you're unsure about any steps or tools required.

Drain fuel: use a small bucket or tubing to collect the fuel

To drain the fuel, you can use a small bucket or tubing to collect it. If you are working on the front filter, there is a drain tube that you can place a container under to collect the fuel. For the rear filter, you can use a small bucket and place it above the drive shaft to catch the fuel. You can also use tubing to direct the fuel flow and minimise the mess. This is especially useful if you are working in an area with strong winds or limited space.

When using a bucket, make sure it is small enough to fit in the tight space above the drive shaft. You may need to carefully manoeuvre the bucket to find the best position to catch the draining fuel. If you are using tubing, you can attach it to the drain valve and direct the fuel flow into an appropriate container. Be careful not to overtighten the drain valve, as the plastic is thin and can snap easily.

By using a bucket or tubing to collect the fuel, you can help to prevent spills and minimise the mess during the fuel filter replacement process. This will make the job easier and help to protect the environment by containing the drained fuel.

Removing the old filter: be careful with the plastic cap and ensure the old gasket comes off

When removing the old filter, be cautious with the plastic cap. The plastic cap under the hood can be easily stripped, so it is recommended to replace it with a billet one. Make sure the old gasket comes off, and be careful with the drain valve as the plastic is thin and can snap if you tighten it too much.

To remove the old filter, you will need to unscrew the filter housing. This can be done with just some sockets. Be sure to get the correct socket size for your model of RAM 2500, as this may vary. For a 2018 model, a 28mm socket is needed, while a 29mm socket is required for older models. You will also need a ratchet with a swivel attachment and a long extension, at least 12 inches, to reach the front filter. A strap wrench can also be useful for removing the filter.

Once you have removed the old filter, it is important to dispose of it properly. Fuel filters contain hazardous waste, so they cannot be disposed of with regular trash. You will need to take the old filter to a designated disposal facility or a service station that accepts used motor oil and filters.

Installing the new filter: ensure it is seated correctly and that the new gasket is in place

When installing the new filter, it is important to ensure that it is seated correctly and that the new gasket is in place. This will help prevent leaks and ensure the optimal performance of your RAM 2500's fuel system. Here is a detailed guide to help you through the process:

First, locate the fuel filter housing. On a RAM 2500, there are typically two fuel filters: one mounted on the left side of the engine and one frame-mounted. Once you have located the fuel filter housing, place a bucket or container underneath it to catch any fuel that may spill during the replacement process.

Next, remove the old filter by unscrewing the filter housing with the appropriate socket size for your specific model of RAM 2500. Be careful not to cross-thread the housing as you remove it, as this can damage the fuel system. Once the housing is removed, take out the old filter and inspect the housing for any signs of damage or debris. Clean the housing if necessary, and make sure that the old gasket is completely removed.

Now, you can prepare the new filter for installation. Ensure that the new filter is the correct type and size for your vehicle. Check the part number and consult your owner's manual or a trusted mechanic if you are unsure. Carefully remove the new filter from its packaging, handling it with clean hands or gloves to avoid contaminating the filter media.

Inspect the new filter for any signs of damage and ensure that it is seated correctly in the housing. The new gasket should be in place, creating a seal between the filter and the housing. Hand-tighten the new filter into the housing, ensuring that it is secure and properly aligned. Do not overtighten, as this can damage the gasket and housing.

Finally, once the new filter is installed, be sure to prime the fuel system before starting your vehicle. This will help ensure that the new filter is functioning properly and that there are no air bubbles in the fuel lines. Refer to your owner's manual or a trusted mechanic for specific instructions on priming your RAM 2500's fuel system.

By following these steps and paying close attention to the seating and alignment of the new filter and gasket, you can ensure a successful fuel filter replacement on your RAM 2500.

Priming the system: turn the ignition on and off multiple times before starting the engine

To prime the fuel system of your RAM 2500, you will need to turn the ignition on and off multiple times before starting the engine. This process helps to ensure that the new fuel filter is filled with fuel and any air is removed from the system. Here are some detailed instructions to guide you through the process:

Firstly, locate the ignition in your RAM 2500 and insert the key. Turn the key to the "on" position, but do not start the engine. You will know the ignition is on when the dashboard lights turn on. Once the ignition is on, turn it back to the "off" position. Repeat this process of turning the ignition on and off several times, usually around 5-10 times, until you see fuel coming out of the bleed valve. This valve is usually located near the fuel filter.

After performing this priming process, try starting your engine. It may take a few attempts for the engine to turn over as the fuel system is now full of fuel. Once the engine starts, let it run for a few minutes to ensure the fuel system is functioning properly. If the engine turns over and runs smoothly, you have successfully primed the fuel system.

It is important to prime the fuel system after changing the fuel filter to ensure the engine receives an adequate supply of fuel and to prevent any air locks in the fuel lines, which can cause engine performance issues. By taking the time to prime the system, you help ensure your RAM 2500's engine runs efficiently and avoid any potential issues down the road.

If you have any issues with priming the system or starting the engine, it is recommended to consult a professional mechanic or refer to your owner's manual for further guidance.
