Optic Sensor Oring for DS Injection Pump

Replacement optic sensor Oring for all DS4 injection pumps. This is the orange o-ring at the very top of the pump that we get a lot of requests about servicing individually.  Now, this is possible!

You'll need to remove the top cover and snap ring carefully as to not damage the plastic optic sensor. We recommend replacing the top cover seal also, available separately.

Includes:

• 1 Specialty O-Ring

Application:

• 1994 & Newer 6.5L diesel or turbo diesel vehicles with DS4 injection pump
