This worked and thankfully tick tick, however, it also went squirt, and poured fuel all over the floor !
A crawl under the car showed it was time to overhaul the fuel pump.
Very messy, however, some of it is waxoil.
Diaphragm perished, but with the heat out here not a surprise.
Points awful !
Valves seemed okay.
Air chamber O ring seal perished.
But a overhaul kit from SU in the UK plus a bit of elbow grease and some hammerite and as good as new.
All working, a little slow motion clip of the points.
Next . . . . fit the pump, then maybe some bling under the bonnet.
