correct. Believe the 3fe runs around 3-4 bar of pressure (50-60psi). stainless tubing is a great option for making new lines and you can order coils of it from summit racing or speedway shop or Jegs or others etc. there also a reinforced plastic hose that works well. I have to go back and look at everything to remember which is the stuff to look at. Saabs ran plastic lines from tank pump to manifold through the inside of the car and they never had a problem. Use barb type fittings and some times high pressure hose for junctions. Or you can get the fancy fittings for connections.I had read that too, I also read that I need new fuel lines to handle the higher pressure of the fuel pump, is that correct?
