One brand new OE Stanadyne Flex Ring Failure Kit for many Stanadyne / Roosa Master DBG, DBM, DC and JDB diesel fuel injection pumps. This comes with the upgraded EID weight cage to permanently fix the flex ring from failing again. Also includes the return connector which gets plugged up when your old flex ring fails and should be replaced because you will never get all those particles out of the spring. These are all OEM Stanadyne parts.
