There is just NO WAY the lobe for the fuel pump could have worn away.
Compare the loading and forces of the fuel pump with one of the valves
that the camshaft also drives!

Personally, I think that replacing a simple thing like a mechanical fuel
pump with a complicated thing like an electric fuel pump plus
wiring plus regulator is NOT going to make things better in the long run.
 From reading the mailing list, I get the impression that most electric
fuel pumps are installed in a desperate attempt to fix an engine problem
that has not responded to other forms of treatment.  Then when it has no effect,
the regulator is added, with similar results.
that's my rant, anyway.
