Several vendors have kits available for this. I replaced my lines when the
tank started to leak from the gaskets around the cross-over vent lines. I went
with the fuel line from Bus Depot since it was reasonably priced and the same
 kind that was original on my 90 Westy (Conte-I believe was the brand) I was
pleasantly surprised when examining the old fuel lines that they had held up
and  looked almost like new after almost 17 yrs. and 250K. That was reason
enough for  me to want the OEM fuel line. Be careful removing the old hose and
re-installing  the new hose on the plastic piece that goes through the firewall.
Some have  opted to run the new line right through this hole without this
piece using a  grommet to protect the line from abrasion. Be sure to replace all
of your hose  clamps and use fuel line clamps so you don't cut into the new
fuel line. I found  that you will need to re-tighten the clamps around the
injectors and fuel rail a  couple of times after the first few times you run the
engine. It's also a good  time to check over the fuel tank and all of the vent
lines and gaskets. I  replaced everything here too. Also a good time to replace
your fuel sending unit  if its old and original. Ben has some good pictures
and explanations of this job  on his web site. Plenty of info on this subject
if you search the archives too.  I also checked over everything at the same
time with the evap canister and  valve. My charcoal had all become compressed and
wasn't allowing the tank to  vent properly (thunk sound after shutting off
the engine as the tank  depressurizes). I removed the canister and gave it a few
gentle thumps until  everything in there moved around again and air passed
through it. If this  doesn't work you probably need a new canister. Good luck
and remember to be  careful with any incandescent shop lights (breaking) and
cell phones (turn  off) with all the fumes and possibility of a spark.
