OEM Stanadyne Brass Pilot Tube (Drive Bushing) for Stanadyne and Roosa Master Pumps

NOTE: Stanadyne Drive Bushing 16320 measures 1.840 inches in length.  It is extremely important that you get the right size for your pump.  We also sell the 16323 pilot tube which measures 1.640 inches in length.  Also, special bushing tools are highly recommended!  Changing out these bushing is not an easy job.  Consider at least calling with questions.

Fitment Guide :

  • Fits Most AG Pump Applications for DB, JDB, and DC Models
  • Stanadyne Drive bushing 16320 does not fit Automotive Application (We do not currently sell a pilot tube that fits any automotive applications)
  • This is NOT the pilot tube you need if the drive shaft comes out with the pump and has a tang drive on the engine end (that’s likely going to be the 16323).
  • If you send us your pump model number, we can tell you for sure which pilot tube you need.

If you need help verifying your application or need any help, reach out to us.  We are here to help!
