  Important Purchase Guidance

  Please confirm your Cum-mins ISLe/QSL9 engine serial number and original fuel pump OEM number before completing payment to avoid mismatched spare parts. If compatibility cannot be confirmed, provide your vehicle VIN or equipment serial number for our free professional matching inspection. We recommend full cleaning of fuel tank sediment and complete fuel filter set replacement during pump installation to reduce premature abrasion of internal precision components
