Recipe - Ford F-150 3.0L Power Stroke V6 (2018-2021)

Reliability build

Reliability tier: aggregated - verify before ordering, see /disclosure/

CP4.2 survival and recovery plan for the F-150 3.0L Power Stroke (mode CP4.2 high-pressure pump failure (contamination cascade)): the same Bosch CP4.2 family as the 6.7 PSD / LML. Prevention is filter discipline (inspect for metallic debris at every change) and optionally a lift pump. A confirmed failure with debris = the full cascade (pump + injector kits) - verify metal-free BEFORE replacing the pump alone.

Parts

• F-150 3.0L Power Stroke Fuel Filter Assembly (Ford JL3Z-9155-AA, 2018-2021) - fuel filter assembly - the debris checkpoint at every service (qty 1)
• F-150 3.0L Power Stroke Fuel Filter Element (Ford JL3Z-9N184-A, 2018-2020) - filter element for the wet half (qty 1)
• F-150 3.0L Power Stroke Lift Pump System (FASS Titanium Signature 140F, 2018-2019) - FASS lift pump (2018-2019) - lubricity/volume protection for the CP4 (qty 1)
• F-150 3.0L Power Stroke High-Pressure Fuel Pump (Bosch CP4.2, Ford JL3Z-9A543-A) - the CP4.2 itself (JL3Z-9A543-A) - metal-free system only (qty 1)
• F-150 3.0L Power Stroke Fuel Injector Kit (Ford JL3Z-9H529-A, 2018-2020) - injector kit for the contamination cascade (verify the -A/-B/-C letter by VIN) (qty 1)

Install order

1. prevention: filter service on schedule; cut open / inspect for metallic debris every change
2. P0087/hard-start appears: check the filter for debris BEFORE ordering parts - metal found means the cascade, not just the pump
3. clean system: replace the pump (firewall-side labor - shop recommended)
4. debris found: pump + injector kit + lines flush - budget the full cascade
