Is it complete? Does it come with the gasket?
Also, do you mind checking to see if one side of the instructions gives info on "improvement" and shows springs/valve body, and the OTHER side shows "corrective" with info on drilling a pressure relief hole? I am looking for the kit with both those options on the instruction sheet.
It's $16.76 online. Prob why you haven't gotten too many responses. Fiero store one comes with filter and new gasket and is the "Newer" version of the one you have for sale. I was going to order the one below. If you are willing to meet or beat their price, I'll happily buy yours, and save it from a miserable/stinky fate in the trashcan. Please E-mail me directly if you want to talk about it.
