Servo One Way Valve
Posted: Tue Mar 24, 2015 5:09 pm
I have fitted a new replacement servo to my S4 Elan and in the instructions it says that it has a one way valve fitted in the servo in the vacuum hose input. Does this mean that it is not necessary to fit an additional valve in line with the vacuum hose? If one is required can anyone recommend one that works. There are quite a few on Ebay.
