Our SU fuel pumps have, perhaps unjustifiably, earned a reputation for poor reliability in spite of the fact that most original pumps function flawlessly for a great many years. Nonetheless, when they do get old and tired and suddenly stop functioning, there may yet be hope! Try lightly tapping on the side of the pump with a light hammer or wrench. This will frequently shock your SU back to life. If this fails, remove the plastic end cover and clean the points. Sometimes, manually separating the points with the ignition on will also be necessary. If this succeeds in getting you to your destination, make plans to rebuild or replace the pump as soon as possible, as these temporary fixes won't keep you going indefinitely.
