Why This Upgrade Matters
The Ford 6.7L's Bosch CP4.2 pump is infamously sensitive to fuel contamination. When the CP4.2 fails, metal shavings destroy injectors, lines, rails, and tank — a $8,000-12,000 repair. A 5-micron upgrade provides double the protection for less than a tank of diesel.
Installation
- Remove factory upper filter and housing
- Clean mounting surface
- Install all-metal housing with supplied hardware
- Attach fuel lines — no kinks
- Spin on new 5-micron filter — hand-tight plus 1/4 turn
- Prime by cycling key ON 4-5 times until pump sound changes
- Start engine, check for leaks
