I sitting here hoping that I'll hear some flames from Ken Wilford, Boston
Bob, Jake Rabe, Ron Salmon telling me that there is a $20 / $90.00 pump
that will fit the CV series Air Cooled Vanagon engine. I can see that
there will possibly be rebuild jobs in my future and I'd like to locate
the lower priced pumps ahead of time. If there is an alternate pump I'd
like to see the part number get into the archives.
