I would use as much hard line as possible ,I am having some problems with braided line on my truck that sat for 2 years,broke engine in and ran it a few times ,then it sat 2 years ,fired it back up and braided lines are leaking from the middle of the line......this was quality braided line too.

I replaed it with rubber line ,but plan to install as much hardline as possible now....no more braided stuff for me.
