Well OK!
Back about 120K miles ago I started adjusting my AFM (just the rich/lean
screw) I kept getting lean burn on #4 spark plug. After swapping around
injectors, replacing injector seals, manifold seals, various heat range
of plugs etc. I was still getting lean burn on #4.
After looking at several fuel systems on WaserBoxers and Vanagons it was
easy to tell that some used a full loop system and others used a dead end
system (one line to the regulator).
Being somewhat of a junkyard dog I decided to try the dual line regulator
and after a little plumbing ingenuity I came up with a full loop system
to accommodate the dual line regulator. It cured my #4 lean burn and has
been on the vehicle ever since and functions very good. There is also an
upside to this since Texas junkyards are almost nil on air cooled and
full of water cooled, the part is readily available to me at about $5.00
so it is cheap to buy and keep spares.
I'm open to the flames on this so let me hear about your experiences of
lean burn on #4 on typeIV aircooled engines.

You can use a part # 0.280.160.200 the part can comes from 75-79 Bug, or
74-83 Van.
I'm running the dual line regulator on my 83 that came from an 87
Vanagon. The early model 0.280.160.200 will require a T but will be in
the right pressure range and should work good. If you don't want to
install a T you need to block one of the fuel lines since later models
are a full loop.
I don't know why you couldn't find this part at a FLAPS. Rocky Mountain
list it at $59.00
I'll explain why I'm running the 87 double inlet regulator if list
members need to know.
