Simply by replacing the several under carpet and under hood rubber 3 and 4 way vacuum connectors plus the yellow one way vacuum valve I got my central locking to hold vacuum from 2 minutes to 1/2 hour, I need to check the trunk and fuel flap elements plus the rubber grommet in the vacuum reservoir next .

It just takes time with the Mity Vac tool .
