I just took apart my tank to change the gaskets, with some elbow grease to get it apart, a spring, a small rubber top hat looking thing, and a metal washer fell out without me seeing where they came from, anybody know where I can find and explosion chart, or a repair manual for pressurized fuel tanks? Even better, can anybody help me over this forum? Thank you all for your time and help. joeyb1180@aol.com
