Vehicle Fitment

This kit is a direct OEM replacement for the following vehicles equipped with the 6.7L Cummins Turbo Diesel Engine:

What's In The Box?

• 1x 68157291AA Mopar Engine-Mounted Fuel Filter
• 1x 68436631AA Mopar Frame-Mounted Fuel Separator Filter

Simplified Installation Guide

Recommended Tools:

• Socket Set (including a 28mm or 1 1/8" socket)
• Ratchet with extension
• Drain pan or container
• Shop rags
• Safety glasses and gloves

Step 1: Frame-Mounted Filter (Rear)

1. Locate the filter housing on the driver's side frame rail, near the fuel tank.
2. Place a drain pan underneath. Open the yellow drain valve and let the fuel drain completely.
3. Using a 28mm socket, unscrew the plastic cap and remove the old filter.
4. Clean the housing and lubricate the O-rings on the new filter with clean diesel fuel or oil.
5. Install the new filter and reinstall the cap, tightening it to the specified torque (check your owner's manual). Close the drain valve.

Step 2: Engine-Mounted Filter (Front)

1. Locate the filter on the driver's side of the engine.
2. Place rags underneath to catch any spills.
3. Use your hands or a filter wrench to unscrew the old filter canister.
4. Lubricate the gasket on the new filter (68157291AA) with clean diesel fuel.
5. Screw the new filter on by hand until it makes contact, then tighten another 3/4 turn. Do not overtighten.

Step 3: Prime the System

1. Turn the ignition key to the "ON" position (without starting the engine) for 30 seconds.
2. Turn it "OFF," then repeat this cycle 2-3 times to allow the fuel pump to prime the filters.
3. Start the engine. It may run rough for a moment. Check for any leaks around both filter housings.
   

Frequently Asked Questions (FAQ)

Q: Are these actually OEM Quality Mopar filters? A: Yes. We are a trusted retailer and guarantee that every filter in this kit is a 100% OEM Quality, factory- OEM Mopar part. We understand the widespread concern about counterfeit parts sold on mass-marketplaces and stake our reputation on providing only authentic OEM components to protect your investment.

Q: How often should I change these filters? A: Ram specifies service intervals in the owner's manual, which is typically every 15,000 miles or annually. However, for trucks that see severe duty—such as heavy towing, frequent idling, or operation in dusty environments—many knowledgeable owners and technicians recommend a more conservative interval of 7,500-10,000 miles to ensure maximum protection and engine longevity.

Q: Is changing the fuel filters difficult? I've heard the front one is tough. A: The job is very manageable for a DIY mechanic. The rear chassis-mounted filter is generally straightforward. The front engine-mounted filter is in a tight location, which is why having the right tools—specifically a 28mm 6-point socket, long extensions, and a swivel joint—is key to success. Our detailed guide above incorporates tips from other owners to help you overcome these challenges.

Q: Do I really need to cycle the key to prime the fuel system? A: Absolutely. This is arguably the most important step after replacing the fuel filters. Skipping this will leave air trapped in the fuel lines and filters. This air can cause the truck to fail to start, run very poorly, or enter a reduced power "limp mode" and set diagnostic trouble codes. Following the priming procedure in our guide is essential for a successful, trouble-free start.

Q: Why does this kit fit 2019-2024 models? What changed in 2019? A: For the 2019 model year, Ram significantly updated the 6.7L Cummins platform. This included a redesigned fuel filtration system that uses this specific two-filter configuration: the engine-mounted 68157291AA and the new chassis-mounted fuel/water separator 68436631AA. This kit contains the exact two fuel filters required for all 2019 and newer trucks. These changes coincided with the introduction of the CP4.2 high-pressure fuel pump on 2019-2020 models, making the use of correct, high-efficiency filters more critical than ever.

Q: What is the difference between ordering one item versus a "bundle"? How many filters will I receive?

A: We've designed our purchasing options to be simple and cost-effective. Here’s a clear breakdown:

• Purchasing One Set (Quantity: 1): Our main product is a complete Filter Service Set. When you select a quantity of "1", you are purchasing one full set, which contains all three essential filters (one engine-mounted fuel filter, one chassis-mounted fuel/water separator, and one oil filter) required for a single vehicle service.

  • Quantity 1 = 1 Set = 3 Total Filters.

• Purchasing a Bundle (e.g., "Bundle of 2"): Our bundles are for customers who want to purchase multiple full sets at once, saving on future services. If you select a "Bundle of 2", you will receive two complete Filter Service Sets.

  • "Bundle of 2" = 2 Sets = 6 Total Filters (two of each type).

In short, think of the product as a "set." The quantity you select, whether as a single item or a pre-packaged bundle, determines how many of these complete sets you will receive.
