You are right. And so is my 6 year old who just said "If browny van has
problems then it might not get us there, we should take blue van."
The Westy is staying home. I put some Sea Foam in the tank as you
recommended and I will revisit this next week. If it's still buzzing after a
few days I'll do your gas can test next weekend.
I'm just wiped and not thinking clearly. After poor running following the
rebuild, entire new brake components all around (that was a week and a half
ago) and now a buzzing pump that started yesterday I'm frazzled.
I'm going to take the EV MV up there this time. I am now frantically trying
to finish that camping cabinet I started awhile back.
Updates to follow.
Thanks again everyone.
Bryan

Sure seems to me like it would be worth investing 30 minutes to run the van
off a can of gas, so the main fuel tank is not in the picture ...
as a test to get an idea if that's the case.( restricted fuel pick-up in
tank causing the noisy fuel pump )
doesn't cost much,, doesn't take long, might reveal very useful information.
Like, what's not to like about that ??!!
supposing it makes no difference..it's still noisy running off a can of gas
( this is basic what I call 'substitute and bypass' diagnostic strategy -
you take the main tank out of the picture to see if that eliminates the
noise ) ...........
supposing it doesn't make any difference - still noisy.
then at least you can say 'it's probably not the tank, therefore the tank
is probably not trying to clog at the fuel pick-up , therefore I'm probably
safe to go on my trip, as far as the fuel tank is concerned.'
seems totally logical in my mind !
I recommend a ratio of time/energy invested in diagnosis versus energy
invested in pursing 'a part' of about 90/10.
Maybe 80/20 ....but quite often it's not 'a part', and it's something dirty,
clogged, corroded , etc. And many of those things respond to cleaning,
lubing, treating etc.
and may The Vanagon Gods smile on all your vanagons !
