UPDATE: This is the OLD installation guide for an older kit that pulls  pressure from the oil sending unit, which is no longer needed because we are now sending the NEW oil filter cap w/ pressure port. The mounting location and the oil return on this guide are still the same and can be used to plan your new installation. 


Installation Guide for the Ecodiesel 3.0L Kit

Assembly and installation should be completed (or modified) by professional/skilled mechanic or technician. 


  • Your kit includes the following:
    • EXTREME X2 filter housing and filter element
    •  1.2 feet and 4.5 feet of 3/8″ hose
    • (a) Ecodiesel bracket with hardware
    • (b) (no longer needed with filter cap)
    • (c) 2 male 6JIC fittings (6MJ-4MP)
    • (d) 3 female 6JIC elbow fittings
    • (d2) 1 female 6JIC straight fitting
    • (e) 1 male 6JIC fitting (6MJ-2MP)
    • (f) 1 elbow 6JIC fitting (6MJ-2MP)
    • (g) Oil filler cap with swivel port
    • (h) (no longer needed with filter cap)

Additional items you will need: Teflon tape or thread sealer, and zip ties, and additional washers if needed.


  • Install elbow fitting (part “f”) securely into the oil filler cap using thread sealer or teflon tape (see image below). Replace your stock oil filler cap with this new oil filler cap.


  • Apply teflon tape to the two straight JIC fittings (part “c”) and insert them into the “IN” and “OUT” port of your EXTREME X2 filter housing. Install as firmly and deeply as possible. TIP: To avoid scratching your new filter you can use the bracket, and a vice, to hold the filter in place while you tighten the fittings. See images below.


  • Insert two female 6JIC elbows (part “d”) into the 1′ hose. Insert one female 6JIC elbow (part “d”) and one straight 6JIC (part “d2”) into the 4′ hose.  TIP: Use oil or water (as lubrication) to insert the fittings properly into the hose. Be sure the hose and fittings are securely connected or you will have a “drip”. See image below for example: 

WHERE TO MOUNT THE FILTER (for the Dodge Ram 1500 Ecodiesel Only)

The mounting location is under the hood on the driver side of your Ecodiesel, right above the suspension. This mount will require that you remove and re-use the suspension mount bolts to secure the bracket (part “a”), and you will also have to remove the “wiring harness” found on the rear bolt. See images below for reference.

After securing the bracket with the suspension mount bolts use the provided bracket bolts to secure the filter housing to the bracket. See the final result below. TIP:  You can pivot and reposition the filter housing easily by loosening the bolts that connect to the side of the filter housing, this can help with installation and maintenance. 


The new oil filter cap is now where you can easily pull pressure (see image below). The oil pressure T fitting  is no longer needed so you can skip that part.

• Remove your stock oil filter cap 

• Install a new filter in your new Insane Diesel filter cap. Be sure to add the o-ring that comes with your new filter to the new filter cap (see black o-ring in image below) 

• Screw the new filter cap into your oil filter housing.

• Apply teflon or sealant to part #e and insert it in the swivel port on top of your new oil filter cap.

• Attached the hose that leads to the port on your EXTREME filter housing marked “IN”.  


  • Locate the stock oil filter housing found on the driver side of your vehicle. Remove the oil filter and allow the oil drain-back valve to release so that the housing drains back into the sump, this will help prevent excess mess when removing the sensor (not all filters drain this way so it’s ok to skip this step).
  • We’ll be working with the TOP of the two sensors. Carefully unfasten the single wire harness from the factory oil pressure switch (see picture below). To disconnect the connector, lift up on the external latch and pull backwards slightly.

  • Remove the oil pressure switch and in its place thread the tee fitting (part “b”) . Important: Be sure to use teflon tape or a reliable thread sealant.
  •  Thread the fitting (part “e”) into the center of the tee fitting. Important: be sure to use teflon tape or thread sealant.
  • Return the oil pressure switch back into the end of your tee fitting. Important: use the provided washer (part “h”) and teflon tape or thread sealant.

See image below for reference.


  • Connect the 1′ hose to the fitting in the center of the tee.
  • The other end of the 1′ hose connects to the “IN” port of your filter housing.
  • Be sure the hose is not near any moving parts, hot, or sharp areas. Use zip-ties to secure the hose in a safe area.

Image below shows how the hose connects to the bottom of your filter.



  • Connect the 4′ hose to the OUT port of the EXTREME X2 filter housing.
  • Connect the other end of the 4′ hose to the oil filler cap.
  • Be sure the hose is not near any moving parts, hot, or sharp areas. Use zip-ties to secure the hose in a safe area.

Important: After connecting the hoses be sure to secure the filter housing in an upright position. 

See image below for reference.


  • Verify all fittings are tight and hoses are safely routed, secured, and protected.
  • For best results change the stock filter and oil at this time.
  • Run engine for 30 seconds and check for leaks.
  • Top-off oil as necessary, the EXTREME filter increases oil capacity about 1 quart (top off oil as you normally would by removing the oil filler cap and pouring oil through the oil filler spout). Check your oil levels.
  •  Now run engine to temperature and drive around the block and verify no engine leaks once engine operating temperature and pressures are reached.

Congratulations! You’ve completed the installation of your EXTREME bypass oil filter!
