Boy that's a surprise Mark, I've never heard of anyone having a
problem with one of their rebuilds.
I'm pretty sure they put all new parts into them. It might have
to lap in for a little while. I think I'd try running it for a
while and see if it seals up. In the mean time I'd stay with it
and keep trying to get hold of Bob Ficken to see what he says.
He is to wipers as you are to truck beds.

You're dealing with a very small volume and it only takes a tiny
leak to bleed a vacuum system that small up to atmosphere, so
you probably wouldn't be able to hear it.
