NOTE: Fittings that use tapered NPT threads are not designed to thread completely into the component. Apply the specified thread sealant and tighten the fitting to the specified torque. Some fitting threads may remain visible after installation; this is normal.

Important Torque Note: Follow the verified torque specification and sealing method for each fitting. Do not apply thread sealant to AN flare connections, sealing washers, O-rings, gaskets, or other non-NPT sealing surfaces. The female hose socket-to-fitting-barb assembly does not use a torque specification. Tighten the fitting barb until it meets the hose socket.

Installation Reference / Video

The installation video is for the Jeep 3.0L EcoDiesel and is intended as a reference only. The engine components, oil pressure port options, oil return configuration, and filter housing assembly are similar to the Dodge Ram 1500 EcoDiesel. The mounting location and certain vehicle-specific installation details differ.

Installation Procedure

Follow the steps below in this order. First identify the filter housing location, pressure location, return location, year group, pressure-port option, and mounting bracket option. Measure and build the hoses before final assembly. The Suspension Mount ZBRCKX12 bracket is installed on the vehicle first. The UTH-E Under-the-Hood Bracket follows its kit-specific mounting procedure using installer-selected vehicle-side mounting hardware and clamps around the filter housing.

1. Find the Filter Housing Location and Confirm the Mounting Option

• Under-the-Hood Bracket: Use UTH-E. This option may require cutting, drilling, trimming of the vinyl/plastic front support cover, and installer-selected vehicle-side mounting hardware. Insane Diesel recommends using rivnuts and bolts. The UTH-E bracket clamps around the filter housing.
• Suspension Mount Bracket: Use ZBRCKX12. This option is not compatible with vehicles equipped with air suspension. Use the Under-the-Hood Bracket instead if the vehicle has this configuration.
• Verify the mounting location provides adequate structure for the mounting bracket and filter housing.
• Verify the pressure and return hoses can reach their connection points using the supplied hose.
• Verify adequate clearance for the filter housing, hose routing, hood closure where applicable, and future filter service.
• Verify clearance from wiring, suspension and steering components where applicable, driveline components, exhaust components, sharp edges, moving parts, and excessive heat sources.
• Confirm the filter housing lid can be removed for future service.
• Plan hose routing before modifying, drilling, trimming, or permanently mounting any bracket.

2. Find the Oil Pressure Location and Confirm the Pressure-Port Option

Confirm whether the truck is a 2014–2019 or 2020–2023 application and whether the kit uses the Filter Cap Pressure Port or Tee Fitting Pressure Port.

• 2014–2019 Filter Cap: use PCED30 with AN06-02MS90.
• 2020–2023 Filter Cap: use PCED30 with AN06-02MS90 and the required 2014–2019-style stock oil filter.
• 2014–2019 Tee Fitting: use TM1010B, D10, AN06-02MP90, and AN06-06FJ.
• 2020–2023 Tee Fitting: use TM1415B, D14, AN06-02MP90, and AN06-06FJ.

Filter Cap Compatibility: Required filters for the oil pressure cap are Mopar part number 68492616AA or K&P Filter S91. The oil pressure cap works with all EcoDiesel 3.0L engines, including 2020–2023 models, but it requires a 2014–2019-style stock filter. Install the O-ring supplied with the new stock filter onto the supplied filter cap.

3. Find the Oil Return Location

The return line connects to the supplied FLLCEDO oil filler cap using the OED O-ring and AN06-02MS90 return fitting. Verify the filler-cap location and planned return-hose routing before cutting the hose.

4. Measure and Build the Hoses

Before proceeding with Step 4, watch The Complete Insane Diesel Hose & Fitting Installation Guide below so you are familiar with the correct reusable hose fitting assembly procedure.

Incorrect Hose Assembly Examples

Correct Hose Assembly Examples

The Complete Insane Diesel Hose & Fitting Installation Guide

1. Determine the complete routing between the planned filter housing location, pressure source, and return.
2. Starting at one end, route the hose from the planned filter housing location to the pressure source and mark the pressure-hose cut location.
3. Starting from the opposite end, route the hose from the planned filter housing location to the return and mark the return-hose cut location.
4. Verify the cut marks do not overlap. If hose remains between the marks, cut between the marks so both can remain slightly longer.
5. Follow a safe and serviceable routing path.
6. Avoid moving components, steering and suspension components, sharp edges, rotating assemblies, exhaust components, and excessive heat sources.
7. Leave sufficient slack for normal engine and chassis movement.
8. Verify the complete routing before cutting the hose.
9. Cut the hose at the verified cut locations.
10. Cut each hose squarely and cleanly. Ensure each cut is free from frayed braid, burrs, or deformation.
11. Remove the socket from the fitting assembly. Insert the hose into the fitting socket until the rubber can be seen touching the bottom of the female threads of the socket. Make sure ALL of the nylon braided covering is fully inside the socket, with no frays or nylon bunching.
12. Lubricate the fitting barb with clean oil and thread the barb into the fitting socket until the barb touches the socket. Ensure while threading the barb into the socket that it is not pushing the hose out of the socket.
13. Assemble the reusable hose ends as shown in The Complete Insane Diesel Hose & Fitting Installation Guide. The female hose socket-to-fitting-barb assembly does not use a torque specification. Tighten the fitting barb until it meets the hose socket.
14. Filter Cap Pressure Option: Install one AN06-04MS90 on the filter-housing IN end of the pressure hose and one AN06-02MS90 on the PCED30 filter-cap end.
    AN06-04MS90 — Pressure Hose — AN06-02MS90
15. Tee Fitting Pressure Option: Install one AN06-04MS90 on the filter-housing IN end of the pressure hose and AN06-06FJ on the tee-system end that connects to AN06-02MP90.
    AN06-04MS90 — Pressure Hose — AN06-06FJ
16. Return Hose: Install the remaining AN06-04MS90 on the filter-housing OUT end and AN06-02MS90 on the FLLCEDO oil-filler-cap return end.
    AN06-04MS90 — Return Hose — AN06-02MS90
17. Before moving on, verify the completed hose assemblies match the selected pressure-port configuration and are correctly identified.
18. Verify both completed hose assemblies are free from kinks and twists.

Important: Do not allow the hose to become twisted during installation. Verify each hose follows a smooth routing path with large-radius bends and does not place side loads on the fittings.

Maintenance

Bypass Filter Element Replacement

This kit uses an EXTREME2 bypass filter on a diesel engine. Replace the engine bypass filter element every 15,000 miles, 250 hours, or once per year, whichever comes first.

Inspect hoses, fittings, filter housing, pressure connection, oil filler cap return, and mounting hardware during engine oil changes and scheduled service intervals.

Extending Oil Change Intervals

For every 100,000 miles already on the engine, Insane Diesel recommends completing at least two regular scheduled engine oil, full-flow oil filter, and bypass filter changes before extending oil or filter service intervals through oil analysis.

No matter what anyone tells you, the only way to know when you can safely run longer on the same oil is through condition-based monitoring with oil analysis. Every engine will respond differently to bypass filtration, and oil analysis provides the information needed to understand the unique trends and condition of your engine and oil.

In order to extend your oil and filter change intervals, you have to get your oil clean first. Once the oil is clean, oil and filter change intervals may be extended based on oil-analysis results. No filter cleans better than Insane Diesel's EXTREME filter.
