Andy-
You are absolutely correct about the AFM switch. The fuel pump should not
be able to run unles air is being sucked into the motor.
Good work.

Question on some Vanagans. I've done extensive work on my 82 westy and know
it pretty well. When I would turn the key on I would here the fuel pump
kick
on...Didn't think much about it until I had to trouble shoot the AFM(air
flow meter). The airflow meter is a potencialmeter and fuel pump switch.
Further into the system I noticed that the rod on the end of the
potentialmeter was meant to touch the beginning of its travel...so this
means it should touch a small copper end block thingy. When I touched it
the
fuel pump turned off (it was missadjusted). Very critical its design to
shut
off the pump when air is not flowing to the engine...what does this
mean?..you stop feeding the fire when you turn the key off and when
involved
in an accident. I know that my 82 westy the afm is set up right the fuel
pump should not turn on when I turn the key...only when I crank it over
should the fuel turn on because the movement of air into the engine causes
the afm to open then closing the circuit to the fuel pump. So if your
Vanagon is not working this way...you may want to check into it. Does any
one disagree???
