Don't go backwards with a carb.
I vote for Megasquirt too.

For less than the cost of a rebuilt AFM you can get fully programmable fuel
and spark control.  The system is speed density, so no AFM is needed.  The
ignition driver is on-board, so no funky expensive VAG parts there either.
The MAP sensor is built onto the board.  If you don't like soldering you can
get these kits pre-built.
Anyone capable of doing an engine swap can figure it out.
I have no affiliation with MS, just a satisfied customer.

> engine but having some probs with the fuel injection I can't figure out,

If the ONLY problem you are having is fuel injection issues, I would
strongly suggest looking into megasquirting the van.
With megasquirt, you are in control of fuel and spark. Running the
engine rich to cool it down a bit is just a mousclick away.

Here are a couple links for you. The first is the megasquirt forum and
the second a dude who has installed one onto his 1977 westy.
