Ful Line Routing, Which Side?

[wmhjr]

You want the lines to come from your tank/cell and cross to whichever side at the rear of the car (like at the rear crossmember) where there is the least opportunity for clearance issues and heat issues. The side you use should be based on your own geometry. If you have a sump mounted electric fuel pump and are running the line straight to your intake without a block mounted fuel pump, it makes no difference at all. If you're running a block mounted pump, you want to run it on the side that the pump is mounted on because you really don't want to have to cross over at the front crossmember. Heat and damage risk. There's usually plenty of room regardless of how you run your brake lines. I have 1/2" stainless supply and 1/4" stainless return along with stainless brake lines all running on the drivers side of my boxed frame. It's tight with the body on, but not a big deal.
