Gaskets included for both LUK and Bosch tandem pumps. Quality of the parts look OK, but the LUK pump on my car still leaked fuel after replacing the gaskets. Bought a secondhand Bosch pump instead which are less prone to leaks. Used the steel pump to head gasket from the kit which seems to have done it's job.
Golf 19tdi 130 with the pd engine everything fitted fine had no problems what so ever. If you have the bosh vacuum pump tho nothing will fit. So a quick look on the pump housing will tell you what make vacuum pump you have.
