The correct replacement is going to depend on the supplemental braking system you currently have. If you have the SMI Air Force One Supplemental Braking System # SM99243 then the Replacement Air Jumper # SM99666 that you referenced would be the correct choice.

If you have the Roadmaster BrakeMaster 9100 or # RM-9160 then the correct part is the Roadmaster BrakeMaster Air Line Assembly # RM-921004-88.
