Yo,   I was a little more' primative' on my approach.

   I totally filled my caps with oil first , then, not having a vacume
pump , took my caps to da garage ,  fired up my 1970 Ford Maverick,
disconnected one of the vacume lines and hooked it up to my caps, one at
a time,......quite a few bubbles came up,...not as slick as Chips set-up,
but it did help,...Beleive it, or not :-)  (ha ha  )

 

                         Dave B.
