It's pretty much just hose n' clamps; 5mm hose for the breather system, and
7mm hose for the rest. The 5mm breather system isn't pressurized, so it
probably doesn't need replacement. I have so far been unwilling to drop the
fuel tank to inspect mine, so I'm not sure how long they are or how well
they age. 4 meters of 7mm will do the entire vehicle, 3 meters if you're
just doing the engine compartment.  Not sure exactly how many hose clamps
the whole system takes, but I think a dozen will do the engine compartment
lines, and 6-8 more should do the rest. I have a 3 meter coil of nice
cloth-sheathed fuel line from VolksCafe

under my rear seat that I've been meaning to use to replace the lines on my
'90, but apparently my plan is to wait until it catches fire before I get
off my butt and do it.
