I have the APS rails as well, and now my fpr is relocated under my tmic. In factory configuration, the hose is maybe 3 inches long. With the relocated fpr it's over 2 feet of hose.

And knowing the importance of this line staying connected and not coming off, should I connect it somewhere else (i.e. bpv line) to make the fpr more responsive to changes in boost/vacuum?
No, the length does not matter as much as having the fuel lines to each bank after the Ts be of equal length (the returns have to be equal and the feeds have to be equal).
