Fuel Filter Replacement Guide For Ram Ecodiesel Engines

The fuel filter in a Ram EcoDiesel truck should be replaced every 10,000 to 20,000 miles, or every 1-2 oil changes, according to the owner's manual. However, some sources suggest that it is necessary to replace the fuel filter more frequently, such as every 15,000 miles or twice a year. The fuel filter is located between the fuel tank and the engine, and it is important to prime the fuel system after replacing the filter. The process of changing the fuel filter is relatively straightforward and can be done at home with basic tools, but it can be messy, and it is important to take precautions to avoid spilling diesel fuel. Some special tools are available to assist with the process and minimise the mess. The average cost to replace a fuel filter is between $90 and $207, but dealer prices can be much higher.

How to drain water from the fuel filter

To drain water from the fuel filter of a Ram EcoDiesel, follow these steps:

• Locate the fuel filter. It is usually found between the fuel tank and the engine, often inside the top of the fuel tank where it connects to the fuel line. In the Ram EcoDiesel, it is located above the rear axle near the fuel tank or above the drive/prop shaft in front of the rear differential.
• Place a container underneath the fuel filter to catch the liquid that will be drained. A plastic container such as an old peanut butter jar, a plastic cup, or a gallon Ziploc bag can be used to collect the liquid.
• Loosen the drain plug/valve/screw. This is usually a small, yellow plastic screw that can be loosened with a Phillips-head screwdriver. Be careful not to remove it completely, as it has a retainer.
• Drain a small amount of liquid (a couple of ounces) from the fuel filter by poking the drain plug up and down a few times. This liquid will be a mixture of water and diesel fuel. Water is denser than fuel, so it settles at the bottom of the filter, and will be the first liquid to come out.
• Inspect the drained liquid. If you see water droplets or a clear liquid that smells like diesel, then it is likely water. Diesel fuel is usually yellow or blue in colour.
• Once you have confirmed that water is being drained, continue draining until you no longer see water coming out. Make sure to screw the drain plug back in tightly before moving on to the next step.
• Replace the fuel filter, if necessary, following the manufacturer's instructions or a reputable online guide/video.
• Prime the fuel system by turning the ignition key to the 'ON' position but not cranking the engine. You will hear the fuel pump running for a few seconds as it primes the system. Repeat this step several times to ensure that any air is removed from the fuel system.

It is recommended to drain water from the fuel filter periodically, especially if you live in an area with poor fuel quality or if you notice any signs of a bad fuel filter, such as problems with starting the engine, stalling, excessive vibration while driving, or rough slow-speed cruising.

The fuel filter should be replaced according to the manufacturer's recommended interval, which is typically every 20,000 miles or every second oil change for the Ram EcoDiesel. However, some sources suggest replacing it more frequently, such as every 10,000 miles or every oil change.

Please note that working with diesel fuel can be messy and may produce strong odours. It is recommended to wear appropriate protective gear and work in a well-ventilated area.

How to know when to replace the fuel filter

To know when to replace the fuel filter in a Ram EcoDiesel, it is important to refer to the owner's manual and the manufacturer's guidelines. While the general recommendation is to change the fuel filter every 5 years or 50,000 miles, it is advisable to check it more frequently, especially if you live in certain states with dirty fuel or experience issues with water in the fuel. Some owners choose to change their fuel filters more often, such as every 10,000-20,000 miles or even twice a year, as a form of cheap insurance to maintain the health of their engine.

There are several signs that indicate it is time to replace the fuel filter in your Ram EcoDiesel:

• Problems with starting the engine, or it takes multiple attempts.
• Stalling, especially while idling at a stop sign or red light.
• Excessive vibration while driving.
• Rough slow-speed cruising, with better performance at highway speeds.

Additionally, you can check for the presence of water in your fuel filter. The fuel filter in the Ram EcoDiesel has a yellow drain valve or screw at the bottom, which when loosened, should release water or fuel. If you notice water, it is recommended to drain the filter and, if necessary, replace it.

It is worth noting that some owners have reported issues with the factory-installed drain valve, which may not function properly and lead to a diesel fuel bath when the filter is changed. Aftermarket solutions are available to address this issue and make the process of draining and replacing the fuel filter easier and less messy.

Overall, keeping a close eye on the performance of your vehicle and maintaining the fuel filter in your Ram EcoDiesel is crucial to ensuring the longevity and optimal performance of your engine.

How to change the fuel filter without spilling diesel

Changing the fuel filter on a Ram EcoDiesel is a relatively simple task, but caution must be taken to avoid spills and to ensure the safety of the person performing the task. Here is a step-by-step guide on how to change the fuel filter without spilling diesel:

• Prepare the necessary tools and safety equipment: Before starting, gather all the necessary tools and safety equipment. This includes a new fuel filter, a wrench or socket set, a container to catch any spilled fuel, gloves, and eye protection. It is also recommended to have plastic clips for the fuel lines, as they may break during removal.
• Locate the fuel filter: The fuel filter on a Ram EcoDiesel is typically found along the fuel line, between the fuel tank and the engine. Refer to the vehicle's service manual or user manual for the specific location.
• Relieve the fuel system pressure: Before removing the old fuel filter, it is important to relieve the pressure in the fuel system. This can be done by removing the fuel pump fuse from the fuse box and running the engine for a short time until it dies. Make sure the vehicle is in park (for automatic) or neutral with the parking brake engaged (for manual).
• Disconnect the battery: Disconnect the negative terminal on the battery to prevent the engine from being started accidentally during the process.
• Place a container under the fuel filter: Place a bowl or bucket under the fuel filter to catch any fuel that may spill during the removal process. Be careful not to use plastic containers that may not be suitable for holding gasoline.
• Remove the clips holding the fuel filter: Use a flat-head screwdriver to pop out the plastic clips holding the fuel filter in place. These clips may break, so it is recommended to have replacement clips on hand.
• Remove the fuel lines: With the clips removed, carefully slide the fuel lines away from the filter and tip them towards the container to catch any spilled fuel. Wear eye protection and gloves during this step to protect against fuel splatter.
• Slide out the old fuel filter: The fuel filter is likely held in place by a metal bracket. With the fuel lines disconnected, slide the fuel filter out of the bracket by pushing it towards the front or back of the car, depending on how it is positioned.
• Compare the new and old fuel filters: Before installing the new fuel filter, compare it to the old one to ensure they have the same dimensions and nozzle sizes. Make sure it will fit properly into the bracket.
• Install the new fuel filter: Slide the new fuel filter into the bracket and secure it in place. Reattach the fuel lines and slide the plastic clips through the holes on the fuel line nozzle to secure them in place. Ensure all connections are tight.
• Lower the vehicle: If the vehicle was jacked up, lower it back to the ground and reconnect the battery.
• Prime the fuel system: Refer to the specific instructions for your vehicle model to prime the fuel system. This usually involves turning the ignition key from "off" to "on" without starting the engine to build up fuel pressure.
• Start the engine and check for leaks: Turn on the engine and let it idle. Check the engine for any fuel leaks and ensure that it is running smoothly.

By following these steps, you can change the fuel filter on a Ram EcoDiesel without spilling diesel. Remember to refer to your vehicle's service manual for specific instructions and take all necessary safety precautions during the process.

How to prime the fuel system after changing the fuel filter

To prime the fuel system after changing the fuel filter, follow these steps:

• For push-button start trucks, push the start button without your foot on the brake. This will allow the truck to go into "run" mode without starting the engine.
• For keyed start trucks, turn the key to the "run" position without starting the engine.
• Repeat the above step a couple of times to prime the fuel system.
• Ensure that you do not have your foot on the brake during the priming process, as this may cause issues with the priming.
• After priming, attempt to start the engine. Depending on how long it has been since the last engine start, you may experience an extended crank time before the engine fires up.
• If you are still unable to start the engine, check for any leaks or issues with the fuel filter assembly. Ensure that the fuel filter is properly seated and the O-ring is installed correctly.
• If you continue to experience issues, consult a mechanic or your local dealer for further assistance.

How to avoid a diesel fuel bath when changing the fuel filter

Changing the fuel filter on a Ram EcoDiesel can be a messy process, but there are some steps you can take to avoid a diesel fuel bath. Here are some tips to help you get started:

• Make sure you have the necessary tools before you begin. This includes a fuel filter housing removal tool, such as the one offered by Geno's Garage, which can help you avoid a fuel spill. You will also need a hex tool or Allen wrench to remove the drain plug, and a ratchet and socket to loosen the filter cap.
• Position an adequately-sized drain pan under the filter to catch any spilling fuel. You may also want to use a plastic bag to collect the fuel and minimise the mess.
• Before removing the filter, loosen the canister a little first. This will let some air in and make it easier to drain the fuel.
• To drain the fuel, first, loosen the yellow drain screw with a Phillips-head screwdriver. Then, poke it up and down a few times to get out as much fuel as possible. Be sure to screw it back in tightly before moving on to the next step.
• To remove the filter, only the bottom portion/cup of the filter housing needs to be loosened. You can use a pair of channel locks to grab the tabs on the bottom cup and crack it loose.
• When installing the new filter, make sure it snaps into place securely and wipe some fuel on the O-ring to help with sealing.
• To avoid getting diesel all over your hands, try to keep your arms above or at the same level as the filter and cap. This will prevent fuel from running down your arms.
• To avoid spilling fuel on your driveway, consider doing this task on an incline so that any spilling fuel runs towards the front of the truck.
• Finally, be sure to prime the new fuel filter by turning the key to the 'on' position and waiting to hear the priming sound end before starting the engine.
