The sample data you provided in post #1 shows the vertical bar character as a field terminator; not a field separator (since there is no data after the last vertical bar on a line). To produce the output you requested with sed, one could try:
Code:
sed 's/"//g
s/^/"/
s/|/"|"/g
s/"$//' filename

Is it possible that there are (numerical) fields that are not enclosed in double quotes?

For an easy substitution you can add a delimiter at the beginning and another one at the end of the line, and delete them afterwards.
Code:
sed '
# add extra delimiters
s/^/|/
s/$/|/
# replace all border "" by "
s/\([^|]\)""|/\1"|/g
s/|""\([^|]\)/|"\1/g
# delete the extra delimiters
s/^|//
s/|$//
' filename
