I would imagine that each car is different, but my Vanagon only
generates 40psi so the return issue isn't much of a problem.  The
higher pressure Audi lines to the injectors need the steel braided
lines to deal with the pressure, but I think the return lines use
regular hose clamps, so that would answer my concerns.  I could be
way off though.
