LS1 fuel return line question

[revhead]

I see some talk about using a single corvette style fuel line and some systems using a return line as well.

My '72 firebird already has a factory return line, but does this really help me out in any way? Obviously it was meant for hose clamps, so I doubt it would be good enough for the pressures of the FI pump. I'm trying to decide to pull them out or not while my subframe is out.
