Identifying fuel lines under the hood

Hey guys,

I am installing a fuel pressure safety switch, and need to identify which fuel line is my supply line. I am looking at the driver's side near the cruise control, I see two lines which I assume are supply and return. It is an 89 Iroc if that helps.

Thanks!

The supply line is thicker than the return line.
