I assume that you will wire brush/sand and apply your favorite anti-rust
coating anywhere it's needed.  If you have power steering, don't neglect the
steel lines that go front to back above the tank.

I know this is heresy to some, but the hard plastic line that connects the
two high points on the tank can be replaced with a flexible hose that is
long enough to be connected BEFORE you raise the tank.
