dover Posted November 30, 2009 Report Share Posted November 30, 2009 I'm not sure what they are called (any help would be appreciated) but the best way to describe it is: leaks down the combustion chamber, has foam around it in a different sizes for different applications, looks like a gun with a rod in it, has the ability to hook up to air and has a guage for it as well. Any information on where to buy one would be great. They use to sell them at NAPA but not longer carry it. Link to comment Share on other sites More sharing options...
