DESCRIPTION
Product Overview
- This essential 2-in-1 maintenance bundle protects your Gen 3 EcoDiesel powertrain by pairing a high-efficiency chassis-mounted fuel/water separator (68436631AA) with a premium top-load oil filter assembly (68507598AA). Designed strictly for the redesigned 2020–2023 Ram 1500 3.0L V6 platform, this factory-match kit traps up to 99% of micro-abrasives, road dust, and moisture before they can disrupt sensitive high-pressure injection pumps or cause destructive oil pressure drops under heavy towing loads.
- The pre-assembled oil cartridge features a factory-spec resin-impregnated synthetic media and comes complete with an integrated heavy-duty composite cap and pre-installed rubber O-rings, entirely eliminating the common seal alignment and weeping errors found on earlier EcoDiesel generations. Paired with a deep-pleated cellulose fuel element built to maintain steady flow in extreme cold, this kit delivers a zero-compromise, leak-free service routine.
Key Features
- The multi-layer pleated cellulose fuel/water separator delivers a precise 5-micron rating and 98% moisture extraction, providing critical protection for the sensitive high-pressure EcoDiesel injection pump.
- Includes premium fuel-resistant and oil-resistant housing O-rings for both filters, engineered to maintain an absolute, leak-free seal across the truck’s full operational temperature range.
- Deep-pleated media in both filters guarantees stable flow rates and consistent oil pressure during harsh cold-weather starts, shielding vital internal components when engine wear risks are highest.
- A single order delivers both essential filters in individual boxes under a unified tracking number, allowing you to complete a full powertrain refresh at our deepest bundle discount.
Replacement Interval
-
Replace the oil filter every 10,000 miles (or 12 months) and the fuel filter every 20,000 miles, ensuring you drain the chassis water separator at every oil change interval to maintain total powertrain protection.
FAQ
Q: Why does the Gen 3 EcoDiesel oil filter include a whole new cap?
A: To eliminate common installation leaks. The Gen 3 engine (2020–2023) uses an integrated cap-and-cartridge oil filter system where the filter element comes pre-secured inside a replacement composite cap. This eliminates the legacy snap-on design from 2014–2019 models, where reused caps and damaged O-rings frequently caused oil weeping.
Q: Can I use the fuel filter from this kit on my 6.7L Cummins truck?
A:Yes, the chassis fuel filter is completely interchangeable. The 68436631AA chassis-mounted fuel/water separator is a cross-platform part shared between 2020–2023 Ram 1500 EcoDiesels and 2019–2024 Ram Cummins 2500–5500 heavy-duty trucks.
Q: What’s the difference between the 2020-2023 EcoDiesel fuel filter interval and the 6.7L Cummins?
A: The EcoDiesel has a slightly longer 20,000-mile interval under normal conditions (compared to 15,000 miles for the 6.7L Cummins). Because the EcoDiesel operates at lower fuel flow rates, its single chassis filter can handle a longer duty cycle. However, if you regularly tow heavy loads, run biodiesel blends above B5, or use low-quality fuel stations, we recommend reducing the interval to 15,000 miles.
Q: How do I prime the fuel system after replacing the EcoDiesel fuel filter?
A:Use the truck's electric in-tank lift pump. Do not crank a dry engine. With your foot off the brake, press the ignition button twice to the RUN position for 30 seconds, then turn it OFF. Repeat this key cycle 3 to 4 times to purge air from the lines before starting the truck as normal.
Q: What should I add if I want to do the air filter at the same time?
A: The engine air filter is the logical third piece — it shares a replacement window with the fuel and oil on the EcoDiesel. The Fuel + Oil + Air 3-Filter Bundle adds the 68441763AA air filter to this exact fuel and oil pair for a complete engine bay service.
