Have a Question about the fuel line that runs length of the body.
On my car the line is made of steel from the fuel pump to just behind the right front fender and then it 's connected to a rubber hose that runs along the frame rail until it get to the rear quarter and then goes back to steel to the tank, it this normal for a convertable or should the line be steel all the way? the rubber line looks factory as it has hold down clips that look original
