I am no SU fuel pump expert. When I got my '67BGT the pump did not work
with power applied to it. All I did was burnish (scrape off the
oxidization) the contacts with some 3/0 emery. I beleive there is an
adjustment so that you can set the "throw over" point. Maybe yours is
Since yours clicks when you apply and remove power the contacts appear
to be ok, but, could be burnt enough to limit the current flow 'so the
pump don' work so good'.
