Im looking through summit racings catalog and trying to figure out what to order. Cost doesnt really matter because its pretty close and both will look just as good on my frame. My main concern is ease of install/cost of fittings and durability.
If also see that they have a sleeve/nut type connector or a AN hard tube adapters that dont require flaring for the aluminum.
If you use aluminum be sure to secure it well, particularly near joints. Small diameter thin walled aluminum will flex pretty easily with vibration and fatigue/ crack near joints over time . Is the aluminum line specfied for use as fuel lines?
