Tom et al
SU fuel pumps are fairly bullet proof if set up correctly but they don't last
forever. We are all familiar with the point issue and the remedies but the
diaphragm will only perform as new for a while. The diaphragm fabric will
deterrorate and more importantly stiffen over time. This may impact the rocker
throw-over/click-over of the points and fuel delivery. End result is that a
diaphragm replacement or at least an adjustment, if you can separate the pump
without ripping something. Might want to add this to your list of spring
repairs. There are a bunch of web sites, blogs and information about adjusting
the diaphragm. This one was sent to Tom off list.
