Locate the drain plug or petcock on the filter housing. Place the oil drain pan underneath the filter to collect any draining fuel.

3. Loosen the filter

Use the appropriate socket wrench to loosen the filter housing. It might be hand-tight or require moderate force.

4. Remove the old filter

Once loosened, carefully remove the old filter. Expect some residual fuel to spill out.

5. Install the new filter

Apply a thin coat of clean engine oil to the gasket of the new filter. Hand-tighten the new filter onto the housing until snug.

Buying Guide: Fuel Filter Water Separator and Oil Filter for 6.7L Cummins Engines

Maintaining a healthy 6.7L Cummins engine is crucial for ensuring optimal performance, fuel efficiency, and longevity. Three critical components in achieving this are the fuel filter, water separator, and oil filter. This buying guide will equip you with the knowledge to make informed choices when selecting these filters for your vehicle.

1. Understanding the Function of Each Filter:

Fuel Filter: Traps dirt, rust, and other contaminants from the fuel before it enters the engine’s sensitive fuel injection system. A clean fuel filter ensures proper fuel flow and protects the injectors from wear and tear.

Water Separator: Separates water from the fuel. Diesel fuel is susceptible to water contamination, which can cause corrosion, engine wear, and even complete engine failure. The water separator filters out this water, protecting your engine.

Oil Filter: Removes contaminants like dirt, metal shavings, and combustion byproducts from the engine oil. Clean oil is vital for proper lubrication, reducing friction and wear on engine components.

2. Filter Compatibility:

It’s crucial to choose filters specifically designed for your 6.7L Cummins engine year and model. Using incompatible filters can lead to improper fit, leaks, and potential engine damage. Refer to your owner’s manual or consult a trusted parts supplier to ensure compatibility.

3. Filter Options:

OEM (Original Equipment Manufacturer) Filters: These are the filters recommended by your vehicle’s manufacturer and are guaranteed to be compatible and meet specific performance standards. They may come at a premium price compared to aftermarket options.

High-Quality Aftermarket Filters: Several reputable aftermarket brands offer filters that meet or exceed OEM specifications. These can be a cost-effective option while still ensuring proper filtration and engine protection.

4. Filter Change Intervals:

Regularly changing your filters is essential for maintaining optimal engine performance and longevity. The recommended change intervals can vary depending on various factors, including:

Driving conditions: More frequent oil changes are typically recommended for severe driving conditions like stop-and-go traffic, towing, or off-road use.

Oil type: Consult your owner’s manual for the recommended oil change interval based on the specific oil you are using.

Manufacturer’s recommendations: Always refer to your owner’s manual for the specific service intervals for your vehicle.

5. Additional Considerations:

Bypass valves: Some fuel filters and water separators come equipped with bypass valves. These valves allow unfiltered fuel to bypass the filter element in case of clogging, preventing engine stalling. While offering a safety feature, they should not be relied upon as a substitute for regular filter replacements.

Micron rating: This refers to the size of particles the filter can trap. A lower micron rating indicates a finer filter that can capture smaller contaminants. However, a finer filter may also restrict fuel flow slightly. Choose a filter with a micron rating appropriate for your engine’s needs and driving conditions.

By following this guide and considering the factors mentioned above, you can make informed decisions when purchasing a fuel filter, water separator, and oil filter for your 6.7L Cummins engine.

FAQs

Is 15W40 good for Cummins?

For 2020 and newer 6.7L Cummins engines, no, 15w40 is not recommended due to potential engine damage. For older models, it might be acceptable in warmer climates.

Are OEM fuel filters better?

OEM fuel filters offer guaranteed fit, quality, and warranty, but may cost more. Reputable aftermarket filters can be a good alternative, but ensure they meet your vehicle’s specifications.

Does a 6.7 Cummins have 2 fuel filters?

Yes, a 6.7L Cummins engine typically has two fuel filters: one located in the engine compartment and another near the fuel tank.

Can fuel filters cause high fuel consumption?

Yes, a clogged fuel filter can restrict fuel flow, forcing the engine to work harder and potentially increasing fuel consumption. Regularly replacing your fuel filter is crucial for optimal performance and efficiency.

How many microns is a 6.7 Cummins fuel filter?

The micron rating of a 6.7L Cummins fuel filter actually isn’t a single, specific value. It can vary depending on the specific filter model and application.

Typically, the micron rating for these filters falls within a range of 2 to 10 microns. Some popular options include:

Mopar NanoNet filter: This OEM option features a two-stage filtration system with a 5-micron outer layer and a 3-micron inner layer.

Aftermarket filters: Many high-quality aftermarket filters offer similar performance to the Mopar option, with ratings ranging from 3 to 10 microns.
