Hi Mark,
I noted the web site details in an email to Chuck... we both think that
the website is probably wrong.
The vanagon doesn't really need more than 35 psi, since the fuel
pressure regulator opens up and dumps excess fuel back to the tank as
soon as that pressure is achieved.
There were euro-spec vanagons with carburetors, so it isn't impossible
that NAPA would list a fuel pump with 4-6 PSI for that application.
My wife's sunroof bus needs a new fuel pump, so I will probably be
visiting NAPA real soon...
Happy trails,
Greg Potts
