im cheap but, iv heard thoughs things are like a rubix cube to mess with.  if u get a rebuilt one do they inspect, pollish and such all teh internal parts? i have a dire need to rebuild the power steering/vaccume pump on my diesle truck. kits is 35buks, factory rebuildt pump is about 180. from what i have read the place doing teh rebuidls realy do a good job refurbishing all the moving parts and such making it well worth the cost. ill prob go this way just for peace of mind when ever im motovated enough to actuly dig that bastard out of the truck.

thats all id think about, a fuel injector pump probably wouldnt hurt to have a simmilar process doen if they do that inaddition to installing the new seals.
