In October my 1985 1.9 L Camper started making a buzzing noise climbing up
a steep mountain in Ashville, N.C. It's so intermittent I couldn't get out
of the van quick enough to trace it down until last week, when we pulled
into a campground and it continued long enough to find out it's coming from
the fuel pump. This is a VW pump dealership installed only last June! The
engine idles fine even when it's making noise. Is this a defective pump or
is there some other reason this could be happening? I'm sure if I take it
to the dealership it will be completely silent when they look at it.
