Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.
How do I know if it is compatible?
We recommend checking the SKU/MPN and Cross Reference list provided above. If your original part number matches any of these, it is a guaranteed fit.
Should I replace the high-pressure pump at the same time?
While not always necessary, if your Gen III Cool Fuel module is open, it is highly recommended to replace the fuel filter (Sierra 18-7977) and inspect the high-pressure pump (866169A01) for debris or wear to ensure long-term system health.
