The parts in this kit include the seats and diaphragm, o-rings and the spring.
If you are slowly getting less and less pressure from your pump, it can be an indication that your regulator/control unit is worn and some of the parts need to be replaced.
If your pump has milky grey oil, you need to replace the main diaphragms in your pump, this kit does not include those parts.
This GS50GI Control Unit is found on several high pressure Hypro Diaphragm Pumps, such as the D813, D1064, D1265, D1516 and on older pumps, such as the 9910-D1554 or D110.
