Diesel Fuel Contamination Kits – Complete Solutions by Bosch

Resolve fuel-system damage the right way with a complete fuel contamination kit. At Express Diesel USA, we stock Bosch-engineered kits designed to restore OEM-spec performance after water, DEF, debris, or metal particulate enters the system. Each kit bundles the major components you need for a compliant, one-and-done repair.

What’s Typically Included

  • High-Pressure Fuel Pump (HPFP) and/or CP-series replacement as applicable
  • Fuel Injectors (matched set), fuel rails, high-pressure lines
  • Fuel filters, seals, and common installation hardware
  • Application-specific components noted on each product page

Why Choose a Complete Kit?

  • OEM-Level Reliability: Bosch components engineered to OE tolerances and flow specs.
  • Do It Once: Replaces all contaminated high-pressure parts to prevent re-failure.
  • Time & Cost Control: One kit, known coverage—minimize come-backs and parts chasing.
  • Fitment Confidence: Model/year-targeted bundles with clear contents and notes.

How to Select the Correct Kit

  1. Confirm Application: Match model year, engine code (e.g., 6.7L Power Stroke, 6.6L Duramax) and emission tier.
  2. Cross-Check Part Numbers: Use the OE/Bosch PNs from your service manual or existing components.
  3. Assess System Damage: If the HPFP grenaded, plan to replace injectors, rails, and lines as specified.
  4. Add Install Items: Fresh filters, clean tank, flushed lines—follow repair bulletin best practices.

FAQ

Why replace rails and lines if only the pump failed?

Metal debris from a failing HPFP can circulate through the high-pressure circuit. Replacing rails and lines prevents residual contamination from damaging new components.

Can I reuse my old injectors after a contamination event?

It’s not recommended. Even microscopic particles can score injector internals. Complete kits ensure long-term reliability and warranty compliance.

Do I need to reprogram anything after installation?

Some platforms require injector coding or fuel system relearn procedures. Check your service manual and follow the product page notes.
