Use as much steel line as you can. Other than that, It needs to be teflon hose or at least teflon coated on the inside. All of the typical AN hose you see on summit, jegs and what not is not even rated for pump gas with ethanol. Even it will degrade but everyone still uses it. Why? I don't know, it shouldn't be allowed for gasoline use.
If it's in your budget, try tech afx, conductive, ptfe hose. They've got several kinds that will work and won't degrade.
