❓ Quick FAQ

Which trucks/engines does this fit?
Peterbilt and Kenworth trucks powered by PACCAR MX-11 and MX-13 turbo diesel engines.

Where does each filter go?

• Oil Filter (1922496): Oil module housing, passenger side — traps soot and metal wear particles.
• Fuel Filter (2277129): Fuel module, driver's side — fine particulate filtration before the high-pressure rail.
• Water Separator (2234788): Also in the driver's side fuel module — coalesces water and larger debris from incoming fuel.

How do I service all three filters?

1. Drain the oil module, remove the cap (36mm socket), swap the oil filter cartridge and O-ring, then torque to 40 Nm.
2. Drain both fuel filters, remove their caps (36mm socket), and lift out the old cartridges.
3. Install new O-rings and filter elements, then torque the caps to 25 Nm.
4. Manually prime the system using the hand primer pump until resistance builds.
5. Cycle the ignition to RUN (without cranking) twice to purge remaining air, then start the engine and check for leaks.
