Stu, and Gary,
Although the original SU pump has a few eroding / arcing points issues,
the mechanical points can be best fixed by replacing the switch inside
the housing. I have owned these pumps for over 50 years in my MG-TD,
Jaguar XK120 and others. I was warned about the pump points, and the
users had a number of solutions (some more effective than others.)
When stopped dead in the fast lane of the 405, the first solution is to
throw open the bonnet, remove your bumper shoot, and give the pump a
good thwack.
Difficult if it starts raining.
The Jaguar mounted the pump under the passenger floor, like the Early
Tiger, under the rear "parcel shelf" panel. Difficult if the hood (soft
top) is up because it is raining.
The easiest cure is to replace the mechanical points set with a solid
state device. Only the points must be changed. At one point Theo Smit
was selling the points replacement kit he designed and made. No better
referral can be had be had.
No, it doesn't rain here much. Which makes every rain-related issue few
and far between, but unexpected.
