My guess is that some of the rubber fittings on top of the tank are no
longer present or have rotted pretty badly. I replaced all mine
maybe 5 years ago on my '81 Westy. There are 3 main ones that I
can recall -- two on the passenger side and one on the driver side.
You can just barely reach them.

The 5 to 8 seconds might be the amount of gas
that the cold-start valve fires in there, although
I'd have guessed more like 2 or 3 seconds. There's another
piece of the FI system (quite near the cold start valve, in
fact...) that has a short timescale also, although
I forget what it is called. If the van's not in a very good state of
tune I wouldn't be surprised at this behaviour; if it is, well,
maybe these bits of info will be a place to start.
