2013-2024 Ram 6.7L 5-Filter Kit Buyer’s Guide (68197867AA / 5083285AA)

The $13 Filter That Almost Cost Me a Fuel System

A friend of mine owns a 2017 Ram 2500 that he uses to haul a fifth wheel through the Rockies every summer. He’s the kind of guy who prides himself on doing his own maintenance, so when the fuel-filter service light came on, he did what a lot of owners do — he searched for the part number, sorted by price, and bought the cheapest kit that claimed to fit.

Six months later the truck started to stutter under load, then threw a low-fuel-pressure code. The shop pulled the filters and found the chassis-mounted water separator had collapsed internally. The media had let water through to the high-pressure pump, and the pump was eating itself. The bill was north of $8,000 — pump, injectors, and a flushed fuel system — all to save maybe forty bucks on a filter kit.

The 2013-2024 Ram 6.7L doesn’t give you a cheap failure mode. It runs a high-pressure common-rail fuel system that spins at over 29,000 psi, and there is no second chance downstream of the filters. The two fuel filters — the frame-rail water separator and the engine-bay secondary element — are the only barrier between whatever came out of your tank and a pump that costs more than some used cars. On this engine, a “cheap” filter isn’t a bargain. It’s a bet with the house.

Why Two Fuel Filters — and Five Filters Total

Every 2013+ Ram 6.7L Cummins runs a two-stage fuel filtration system, and that’s the first thing new owners get wrong.

The chassis-mounted fuel/water separator sits on the rear frame rail and does the coarse work — catching free water and the sediment that settles out of the tank before it reaches the pump. The engine-bay secondary filter does the fine filtration, polishing the fuel down to the micron level before it hits the injectors. Both get changed at the same time, and buying them as a kit is the only way to guarantee you get both stages in one box.

On top of the two fuel filters, the full service stack is five filters total:

The oil filter (5083285AA) is a workhorse that’s been spec’d across Cummins trucks since 1989, and it’s one of the most-counterfeited diesel filters on the market. The air filter keeps the turbo’s compressor wheel from sandblasting itself. The cabin filter is the one most owners forget exists. And the transmission filter is the one most “complete” kits quietly leave out.

The Year Trap: 2018 vs 2019

This is the part that trips people up, because “6.7L Ram” sounds like one truck. It isn’t. Ram made a hard break in the fuel system between 2018 and 2019, and the chassis-mounted fuel filter does not carry over.

The 2013-2018 trucks use a spin-on canister for the water separator; the 2019-2024 trucks switched to a cartridge element that drops into a permanent housing with a 28mm cap.

The two do not interchange. If a listing says “fits all Ram 6.7L 2013-2024,” close the tab — that’s the tell that the seller doesn’t understand the platform, and you’re about to buy a return label instead of a filter.

There’s also a transmission catch. The 5013470AE filter fits the 68RFE transmission — which is what most standard Ram 2500 and 3500 pickups have. If your truck is a 3500 High-Output or a Chassis Cab with the Aisin AS69RC, you need a different filter (68224232AA). Check your glovebox build code or dipstick before you commit, because the two transmissions are completely different units.

What You Actually Pay: The Real Comparison

Prices checked September 2026 across the channels that actually carry these part numbers.

The honest read: Doc’s Diesel’s “five-filter” kit looks like a near-match at $191-193 — but it’s actually a five-piece kit that stops short of the transmission filter. Add a 68RFE transmission filter on your own (another $40-50) and you’re at $235-245 before tax. The TruckTok kit bundles all six pieces — including the transmission filter — into one box at $197.10, which is cheaper than “Doc’s five-filter + a separate trans filter” and dramatically cheaper than buying everything separately from a Mopar dealer — who’ll quote you around $700 just to change the two fuel filters.

The $56.99 Amazon white-label kit looks tempting until you read the fine print: no micron rating, no water-separation spec, no published efficiency numbers. On an engine where the fuel filter is the only thing protecting the high-pressure pump and eight piezo injectors, that’s not a bargain — it’s a gamble.

What to Look For When Buying

Before you click buy, check four things:

1. Is it the right chassis filter for your year? The 68197867AA (2013-2018) and 68436631AA (2019-2024) are completely different parts. A listing that claims “fits 2013-2024” without asking your year is a red flag.

2. Is the transmission filter actually in the box? Most “complete” five-filter kits stop at fuel, oil, air, and cabin — they leave out the transmission filter. If the 68RFE filter matters to you, read the contents line, not the headline.

3. Is the water-separation spec published? The chassis fuel filter’s whole job is stripping water before it flash-boils to steam at rail pressure and erodes the injector tips. A kit that won’t state a micron or water-separation rating is asking you to take it on faith.

4. Is it the 68RFE or Aisin filter? If your truck has the Aisin AS69RC (3500 HO or Chassis Cab), the 5013470AE filter in this kit is the wrong one. Verify your transmission before you commit.

Installation: Five Filters, Four Locations

Rear Chassis Fuel/Water Separator Replacement.

Located on the passenger-side rear frame rail above the driveshaft.

1. Unplug the Water-In-Fuel (WIF) sensor connector by depressing the release tab.
2. Crack the lower drain valve to bleed off accumulated water into a drain pan.
3. **2013–2018 Models:** Spin off the **68197867AA** canister using a filter wrench. Transfer the WIF sensor to the new filter with a lubricated O-ring.
4. **2019–2024 Models:** Unscrew the **28mm plastic cap**, replace the internal **68436631AA** cartridge element, and install fresh cap O-rings.

Engine-Bay Secondary Fuel Filter Replacement (68157291AA). 

Located under the brake master cylinder on the driver side.

1. Open the yellow drain valve 1/4 turn to break the siphon and drain residual fuel into a pan.
2. Unscrew the plastic housing cap using a **28mm socket** (or 1-1/8").
3. Replace the **68157291AA** cartridge and BOTH O-rings (the small center stem O-ring and the large cap O-ring). Lubricate with clean diesel fuel or grease to prevent pinching.
4. Torque cap to printed specification and perform **4 to 6 Key-ON priming cycles** to purge air before starting.

Engine Oil & Filter Replacement (5083285AA). 

1. Drain 12 quarts of engine oil from the oil pan plug.
2. Access the **5083285AA** oil filter from underneath the passenger side behind the AC compressor.
3. Spin off the old filter, verify the old rubber gasket didn't stick to the engine pad, pre-fill new filter with fresh oil, and spin on hand-tight plus 1/4 turn.

Engine Air Filter Replacement (53034051AB). 

1. Remove the three front screws on the passenger-side airbox using an **8mm socket**.
2. Swing the airbox lid up and slide the old panel out from the four rear tabs.
3. Seat the new **53034051AB** filter into the housing, ensuring perimeter rubber seals sit flush before tightening screws.

Cabin Air Filter Replacement (68406048AA). 

1. Lower the glovebox by releasing the dampener arm and depressing side stops.
2. Unclip the HVAC filter door and slide out the old element.
3. Insert the new **68406048AA** filter with **AIR FLOW arrow pointing DOWN**.

68RFE Transmission Dual Filter Service (5013470AE). 

1. Loosen 15 oil pan bolts (8mm) and tilt the pan forward to drain transmission fluid.
2. Remove the internal flat sump filter held by a **T-25 Torx bolt** *(Torque to 40 in-lbs during reassembly; do NOT touch valve body bolts)*.
3. Spin off the external canister filter using a **65mm wrench**. Gently hand-thread the new Mopar spin-on filter to avoid cross-threading the soft plastic nipple.
4. Clean pan magnets, install a fresh pan gasket, torque bolts to **8–10 ft-lbs** in a crisscross pattern, and perform a simple gravity refill *(never use pressurized flushing)*.

Five Expensive Mistakes

Mistake #1: Buying the wrong year’s chassis filter. The 68197867AA (2013-2018) and 68436631AA (2019-2024) do not interchange. Order the wrong one and you’re doing the job twice, or forcing a filter that doesn’t seat and leaks on the first drive.

Mistake #2: Assuming “five filters” means five filters. Read the contents line. A lot of kits advertise five filters but only pack fuel, oil, air, and cabin — the transmission filter is the one that gets silently dropped.

Mistake #3: Gambling on a no-name kit to save $40. The white-label kits strip out the water-separation layer and skip the micron spec. On a common-rail engine at 29,000 psi, that’s how you finance a pump and injector rebuild.

Mistake #4: Skipping the transmission filter for “one more oil change.” The 68RFE’s sump filter catches clutch material and metal shavings before they reach the valve body. Ignore it long enough and the shift quality degrades, then the valve body sticks, then you’re into a rebuild.

Mistake #5: Confusing the 68RFE and Aisin filters. The 5013470AE (68RFE) and 68224232AA (Aisin AS69RC) are for two completely different transmissions. Order the wrong one and it won’t fit — or worse, you’ll find out at 3 a.m. with the pan off.

Frequently Asked Questions

What’s the difference between the 2013-2018 and 2019-2024 fuel filters?

The chassis-mounted fuel/water separator changed. 2013-2018 uses the 68197867AA spin-on canister; 2019-2024 uses the 68436631AA cartridge in a permanent housing. The engine-bay filter (68157291AA) and oil filter (5083285AA) stayed the same across both.

Does this kit fit my 2018 Ram 3500?

Yes, if it’s a 6.7L Cummins with the 68RFE transmission. The 2013-2018 chassis filter (68197867AA) is included, and the 68RFE transmission filter (5013470AE) matches the standard 3500.

What if I have the Aisin transmission?

The 5013470AE filter in this kit is for the 68RFE. If your truck has the Aisin AS69RC (3500 High-Output or 3500/4500/5500 Chassis Cab), you need the 68224232AA filter instead. Check your glovebox build code or dipstick before ordering.

Why do I need two fuel filters?

The chassis-mounted separator does the coarse work — catching free water and sediment — while the engine-bay filter does the fine filtration down to micron level. Both are needed to protect the high-pressure pump and injectors, and both should be changed at the same time.

How often should I change each filter?

Oil filter every 7,500 miles, both fuel filters every 15,000 miles, and the air and cabin filters every 30,000 miles (or 24 months). The transmission filter is a longer interval — typically 60,000 miles, or 30,000 under severe towing.

Is the transmission filter hard to change?

It’s the most involved of the five — you drop the oil pan (which has no drain plug), swap both filters (the sump filter and the spin-on), check the magnets, and re-seal with the gasket. It’s a few hours for a DIYer, but it’s the difference between a clean-shifting 68RFE and a valve-body rebuild.

What happens if water gets past the fuel filter?

At rail pressure, water flash-boils to steam and erodes the piezo injector tips. The truck starts to run rough, then throws codes, then you’re replacing injectors at several hundred dollars each. The chassis fuel filter’s water-separation layer is the only defense.

Why is the transmission filter left out of most kits?

Because it’s a different category of service. Fuel, oil, air, and cabin filters are quick top-side jobs, while the transmission filter requires dropping the pan. Sellers leave it out to hit a lower price point — which is exactly why this kit bundles it in.

Can I just change the fuel and oil filters and skip the rest?

You can, and plenty of people do — which is why the air, cabin, and transmission filters are the ones that never get changed. Bundling all of them is the only reliable way to actually replace the three you’d otherwise forget.

Is the high-pressure pump a weak point on these trucks?

The 2013-2018 trucks run a Bosch CP3, which is genuinely one of the most durable pumps ever put in a diesel pickup. The 2019-2024 trucks saw the CP4.2 arrive — and a widely-publicized recall that switched many of them back to the CP3. Either way, the fuel filters are the only barrier between your tank and the pump, so clean fuel still matters.

What’s the cheapest safe way to buy all five filters?

Buy a matched kit with published specs — like this one — rather than piecing together white-label filters from four sellers. The kit route guarantees the right part numbers for your exact year and transmission, and gives you the water-separation spec in writing.

Should I flush or drain-and-fill the 68RFE?

Drain-and-fill, never a pressurized flush. Chrysler’s own service guidance calls for drain-and-fill only — a flush forces fluid backward through the valve body and can shove debris into solenoid passages where it does real damage. Drop the pan, let gravity do the work, swap the filters, and if you want to turn over more of the fluid, do a second drain-and-fill a few thousand miles later.

Get All Five Filters, in One Box

If your 2013-2024 Ram has been running on “whatever was on sale” filters, or the transmission filter is still the one it left the factory with, this kit closes the gap. One order puts the dual fuel filters, oil filter, air filter, cabin filter, and the 68RFE transmission filter in a single box — matched to your year, OEM-spec, and ready for one long afternoon in the driveway.
