The Story

Description

The CU-3867043 is the OEM-spec injector feed tube O-ring for the 1998.5-2002 5.9L 24V Cummins. Small part, easy to forget, common cause of a fuel leak at the injector base when it gets old or pinched during reassembly. Replace this O-ring any time you pull the injectors — whether for testing, replacement, or a top-end rebuild. It's the kind of $6 part you absolutely don't want to skip.

Sold individually; an inline-6 24V Cummins uses six total. Order quantity to match what you're servicing.

Features
  • OEM-Spec Injector Feed Tube O-Ring for 1998.5-2002 5.9L 24V Cummins
  • Sold Individually — Order Qty 6 for a Complete Set
  • One-Time-Use Part — Replace Any Time Injectors Are Pulled
  • Stops Visible Fuel Weep at the Injector Base
  • OE Cross-Reference: Cummins 3867043
Notes
  • If you've got visible fuel weep at the injector body on a 24V, the feed tube O-ring is the most common culprit. Cheap to replace, prevents a no-start no fuel-pressure scenario.
  • Lightly oil the new O-ring before reassembly — installing dry can pinch and tear it.
