In swapping my 216 for a 235 I came across a discrepancy today and am not
sure whether it even matters, or what I should do about it. My 216 had a
much larger vacuum line coming off of the intake manifold (maybe 3/8"), as
compared to the 1/4" line that comes off of my 235's offy dual carb intake.
The line routes over to a check valve/distribution box which takes the
various vacuum lines to their final destination. Will the 1/4" line suffice
for the Hydrovac Booster and my windshield wipers? Can I pull additional
vacuum from somewhere else? I would like to avoid buying a new dual action
fuel pump but have heard that it really improves the vacuum for wipers etc.
Thanks in advance.
