Sorry, I was a bit unclear, the new diaphragm was unable to pump enough gasoline into the carbs and the engine died on a slight hill. Rather than try and find what was wrong with the rebuild, we went for the electric. Since the rebuild, I do not believe that I got any gas in the block, although it hardly ran enough to have gotten much in if it did leak. We did not order a kit from SS, we were using parts-house supplies, perhaps that is the way I should go about recovering my mechanical pump (and I'll be careful with the wire brush :-).

Patrick, SV, Richmond.

p.s. if you ever put an electric pump on don't be an idiot and power it from the coil, causes a nicely calibrated tach to jump like crazy.
