If it were me, in terms of fuel quality, my first concern would be any
sediment or water that's in the tank or lines. But, if the fuel filter
is ok, it should protect the FI's etc. from sediment. If filter ok,
I'd try running it. If it ran, I'd consider changing the fuel filter
but for sure change the fuel hoses.

Are the fuel hoses etc. in engine bay ok?

If I had doubts about the fuel and wanted to drain it, I'd clamp off
the hoses at fuel pump/filter, hook up a generic new fuel filter to
fuel tank outlet hose, unclamp this hose, and drain it from the tank
through filter into a clean gas "can". Then I'd run that fuel a little
at a time in another vehicle. Replace the fuel filter on the Vanagon,
install new fuel lines at pump/filter, (and engine bay if needed) put
in new gas.

But that's just me :)

YMMV,

Neil.
