<Actually, both are needed. The golf/jetta has a prepump or transfer pump in
<the gas tank which delivers fuel at a modest pressure to the fuel reservoir
<and high pressure fuel pump module. The details are different for CIS, CIS-E

<pump to supply the golf fuel module.

I beg to differ on the prepump, it is needed in the Golf/Jetta because the
fuel is drawn up and out the top of the tank.  Since the fuel outlet on the
Vanagon is down low on the tank the pump gets a positive head even without
the prepump.  As long as you don't mount the pump somewhere up high you
shouldn't need the extra pump.  I wouldn't have a clue how you would mount
it up high in a Vanagon to begin with, so this is a non-problem.  I've
driven my van 8000K without a prepump and have had no problems with fuel
delivery.
