Check for a leak in the vacuum tube?

iv replaced all the 4mm vaccum tubing including the one to the back of the dials!

I take it that all the other functions of both sets of clocks work.
There is an FAQ which indicates that this problem with the MFA is usually a defective speed sender, on the back of the clocks.
If you look at the FAQ for 'Changing Instrument console warning lamp' in the third picture down you will see the speed sender (in this case the yellow block - some are black) next to the connection for the speedo cable.

ye all other functions of the digital display are working! I've been asured that the mfa was all working when the dials were removed from the other rocco!
