Fuel & Emission Parts

Genuine OEM Fuel & Emission Parts

A failing humidity or NOx sensor, a clogged fuel control housing, or a DEF header that's lost calibration can all trigger the same result — a derate, a fault code, and a diesel engine that won't run within emissions compliance. Because these components work together to manage combustion, exhaust treatment, and fluid delivery, a wrong or generic replacement often means the same fault code returns within weeks. That's why every part in this collection is genuine OEM, matched to the manufacturer's original part number.

What's in this category

This collection covers the core fuel and emission system components for heavy-duty diesel engines, including:

  • Humidity & exhaust gas pressure sensors — feed combustion and emissions data to the ECM
  • NOx sensors — monitor nitrogen oxide levels for SCR system compliance
  • Fuel control housings & fuel filter housings — regulate and filter fuel delivery to the engine
  • Fuel pumps — deliver fuel at the pressure your engine needs to run correctly
  • DEF headers, multifunction head units & tank jumper harnesses — manage diesel exhaust fluid level, quality, and delivery
  • Diesel exhaust fluid headers — tank-mounted assemblies for DEF systems
  • Brake booster cylinders with motor kits — hydraulic power assist for heavy-duty braking

Brands we cover

This collection includes genuine OEM parts for Cummins, International/Navistar, Mopar, Detroit Diesel, Volvo, Mack, Capacity, Hyundai, JLG and more.

Why order your fuel & emission parts here

  • Genuine OEM only — every part is matched to the manufacturer's original part number, not a generic equivalent
  • Built for accurate fitment — listings include the exact OEM number so you can verify the right part before you buy
  • Fast turnaround — ships quickly to minimize downtime and keep your engine in compliance

FAQ

What does a humidity sensor do? It measures intake air humidity so the ECM can adjust fuel and emissions calculations. Failure can trigger fault codes or unnecessary derates.

NOx sensor vs. DEF sensor? A NOx sensor checks exhaust nitrogen oxide levels to confirm the SCR system is working; a DEF sensor monitors DEF level and quality in the tank.

Signs of a failing fuel pump or housing? Hard starting, rough idle, power loss under load, stalling, or a fuel-related check engine light.

Genuine OEM or aftermarket? All parts here are genuine OEM — no generic substitutes.

How do I find the right part? Match the OEM number on your old component or check your service manual, then search that number above.
