I am  looking to cut down on the smoke.

any thoughts?

The  pump is pretty fresh rebuild, 1.9NA pump with about 10K miles on  it.
Injector nozzels are new as of about 10K miles as  well.




Black smoke is too much fuel for the amount of air or potential to  burn 
efficiently. 
Usual culprits are dirty air filter or worn injectors.  Pump turned up  too 
high also but 
make sure all else is up to snuff before turning the pump  down.  In your 
case it 
sounds slight.  Not a big enough exhaust would do it as well, or  partially 
clogged.
 
  Somewhat similar note...
Today I was noticing the pickup black smoking way more than I'd like.   
It'd been 
getting worse lately.  I know it needs an air filter but didn't think  it 
really had gotten 
THAT bad.  I was driving home down a canyon and decided to give it an  
Italian tune-up.
I drive it softly since the exhaust flex cracked (and smokes underneath)  
plus aiming for 
good mileage, plus a lot of short running so I figured (as the Aardvark  
said) "It couldn't 
hoit!"  So I came out of the corners in 3rd gear to the governor a  bunch 
and wow, it 
didn't smoke anywhere NEAR as much by the time I got to the highway!   :-)  
I figure I 
was getting buildup on the valves and managed to blow it off.  Back in  
town it was 
snappier, free-er feeling and wound up much more quickly.
  I figure in a Vanagon, you pretty much wrap the crap out of it most  of 
the time anyway 
though...
