Thanks Grant, I figured there must have been something like that around.
Scott, they arent that expensive to overhaul, just time consuming. I have a pile of old hydrovacs to chose from. The kits are usually about $50 for most of the seals, and for a complete kit that has everything it shouldnt be more then $100. I already have one that I rebuilt last year and an extra kit on the shelf, so all I have to lose is my time involved.
Thanks, Jeff
