As far as the reference line for the fuel pressure regulator goes, does the length of it matter?

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?
