Getting ready to do my first spark plug replacement. I have read the numerous posts on here and they have been very helpful. Still have a couple of questions though.

1. In replacing the tubes/o-rings several posts have referred to a "Marine Plug Puller" for getting the old ones out. I have searched the internet high and low and cannot find such an animal. Is it called something else? Would Harbor Freight or Craftsman carry this tool?

2. Do you really need the $45 tube of grease? Could I use good old white lithium grease? Do I even need grease?

Thanks for your time and help.
