I also suggest putting a small bit of flare on the end of the tube if
you plan on using a fuel line to extend the line down to the frame. I've
had a few rubber on cut off metal lines work their way off. Several were
under pressure, but at least one was not. Since I started flaring the
end of the tube I have not had one come loose.
Peace,
Pat
