I rooted around a bit looking in the forum for this topic but did not see anything. Anyway, kinda curious if it is correct that a stock AC car used the fuel return line connecting from the fuel filter to the return line and a non-AC did not? If correct, did a non-AC car have both lines routed on the frame, and if so would this line have been capped or something? Mine is a non-AC car but had an aftermarket AC system installed (which is not going back on) and the filter had the vapor return connection connected back to the return line which I'm assuming got hooked up as part of the AC install. So based on that I guess both lines were installed, but Figure 3-3 in the Gran Sport Supplement seems to suggest otherwise. Like I said, just curious.
