I have been contenplating the desaster prevention kit also, its funny, I look at it every year and don't buy one. My procastanation has paid off though. the S&S diesel desaster prevention kint V2.1 is the gold standard. all factory quick conect fuel fitting making instalation a lot less prone to leaks. It has also been out long enough there are several copy cat kits from overseas that are significantly cheeper.
HERE is a link to the S&S product page and you can scroll down to see what is involved with the instalation also.
