Can this be rebuilt? I believe the diaphram is shot as I get zero vaccum and zero presure with the pump running and checking at the pump. $300+ seems a bit steep for a replacement. I have access to one on a 86 560 SL. Part #'s do not match acording to online part catalogs, but can this newer pump work in the 83 380 SEL?
PO removed all the vaccum lines in the drivers door and the line running to the L. rear. What is the bag limit per year on POs? ... Or is there a bounty? Say $5K/ ear?
