P/S low pressure return line ?

I have a 72 Scamp 318 with Federal P/S pump. Has had a leak- Got in to look closely before I ordered high pressure line- turn out it is the return line that is leaking. Is there anything special to P/S about this hose- or can I just use gas line hose I have?
thanks for sharing your knowledge and experience with me again
Leaking in the middle or on the end? Doesn't really matter. NAPA has it by the foot. So does a fastener company in town.
