I didn't look in the book......
But if it is the case, add a new ground wire for the pump, right by the pump
!
I suspect that air-cooled vnaaogns will have weaker gournds in general,
compared to later water-cooled vanagons, as I notice the later vans have
better gournds on them. On an air-cooled where it's push-on spade connectors
for fuel injection grounds, it's screw and eye terminals on the next model
up, the 1.9 wbxr.
I notice that where it's a since wire temp sensor for the ECU on air-cooled
vanaongs, it's a two wire connector with the return/ground for the signal
being built into the harness, and like that on 2.1's too.
Any time you see a company upgrade something like this, that tells you the
'old way' was weak. VW tradiationally has low cost and cheap wiring, and
they gradually improve it over the years, in small ways like this.
On Subaru engine conversions, I put all kinds of redundant grounds on them
for the fuel injection harness. Grounds deteriorate with age too,
corrosion builds up.
There is a way to measure in milivolts, the 'voltage drop' across a ground
connection. It should never exceed about 300 kilovolts.
There may be vanagon people who know all kinds of things electronically
about how things work, but they may not be reading profession car repair
trade magazines, which is where I get stuff like this 300 millivolts max
allowable on a ground connection.

So the earlier models have the ground running to the front by fuse
panel as per Bentley?
Or did I read Bentley wrong?
(soon to be former "air cooled mind is dying to know --- ;^)
IIRC, on mine, the FP ground wire is located in the engine bay. As you
suggest.
