hello, first off I'm a newbie to z cars and to hybrid. I tried to find some info but have been unsuccessful. I recently purchased a pallnet fuel rail and a new aeromotive fpr, and I'm unsure of how to plumb everything together. do I feed to fpr then rail then return from other end of rail? I ask because there is a bypass on the fpr is that the return line? or is the rail supposed to be dual feed or loop like the stock setup? thanks for any help
