I have a 1987 1.6TD engined van and have a problem with the LDA valve fitted on the injection pump. The problem is that the vacuum pipe is not connected and I cannot find the pipe. I have had a good look and can see a vacuum pipe connected to the a unit on the turbo (waste gate?) which in turns seems to go to the inlet manifold but no pipe to lda valve. The van runs well but will really slow on a hill as I assume not enough fuel is been fed.
Can anyone help please?
