MK11 wont start

Just finished gluing and refitting trim on B column Took out driver seat seat. It was the fuzzy stuff that had come loose

Next but one step is to check vacuum Don’t know much about that , so advice welcome Do I check it at the manifold (that is hard as I have to take battery out to get at the nut . Unless I manufacture a spanner to do the job) Ot do I unplug the brake booster If so do I clamp the distributor vacuum line.

What am I looking for and what does a weaker vacuum signify

Thanks in anticipation

Mike
