Five years ago I replaced the fuel lines on my '84 7 passenger with that
in Vanagain's kit and reused the old sleeves.  It's still doing fine.

Four years ago I replaced those on my '85 Westy with hose from BusDepot
and reused the sleeves.  In June, I put a rebuilt 2.1 engine into it
and, just to start with as much as possible that is fresh, I replaced
the fuel lines with hose I got from Boston Bob and new sleeves from
BusDepot.  The old stuff I took out wasn't leaking and still looked good.
