Questions about Gas tank

[Champz]

file:///C:/DOCUME%7E1/Sieufei/LOCALS%7E1/Temp/moz-screenshot.pngThere is a leak on my car from the inlet to the gas tank. I cut a off portion off where it was leaking.

The questions is, should i be expecting any problems by replacing it with a rubber hose or a flex metal pipe

thanks in advance
