All Vanagons have 7mm (not 8mm) fuel line from the fuel pump back. On
vehicles with a plastic fuel filter in front of the fuel pump, the diameter
is different up to the filter - 11mm, as I recall. On vehicles that only
have a filter behind the fuel pump, it's 7mm all the way from front to back.
From the fuel pump back, 20 feet is far more than you would need.  In fact,
even 10 feet is probably more than you would need, I suspect. But obviously
you would need more if you also are replacing the line from the tank to the
pump.  Continental and Cohline (both German companies) make appropriately
rated high-pressure hose. Continental's is smooth-jacket, Cohline's is not.
There is also plenty of fuel line out there that is not rated to handle for
the Vanagon fuel injection system, and can be dangerous. Stick with someone
who knows Vanagons (such as myself, Vanagain, Volks Caf�, or your local
dealer if you are independently wealthy) to be safe. 

I sell the fuel hose for $5.95 per meter (about 3 feet):
