Fuel pump lines, one 0-ring or two??? HELP!

Ok,
Had to replace the fuel pump assembly on my 2007 new body style because supply line was rusted and leaking? I figure that I may as well replace the quick connect O-rings while everything’s apart and the box is off the truck. Only problem I have is I cannot find a drawing or reference to the O-rings for my truck. All older model GMs that I look at have two o-rings and a spacer fitted to each quick connect. My truck appears to have had one a spacer that was fitted outside a single o-ring per fitting. Is this the way our/my trucks should be or should I have two o-rings per fitting? Do anyone know where I can find a drawing showing one or two o-rings? Also is there an easy way to get the spacers out to allow me to change the inside o-rings?
Thanks,
2007 new style, 6.0 Vmax
