I can tell a pretty convincing story for either pump.
Pulse pump
Good news:
Needs no battery (weight savings)
No wires to connect (or reconnect)
Rebuildable
lighter than electric pump
Bad news:
Develops pin hole leaks in diaphragm that can mask problems
Harder to start with empty fuel bowls
Limited (although adequate) availability
Electric pump:
Good news:
Allows pre-fill of fuel bowls minimizing crank/pull starting
Provides slightly higher pressure
Facilitates purging fuel cell
Sold literally everywhere
Bad news:
Dead battery, dead pump
heavier than pulse pump
No rebuilds
I do not see the need for redundant pumps of any type.
I can do the same thing for starting solutions.

Subject: [F500] Which Fuel Pump
I've got an electric pulse pump that is nearly new and a mechanical/vacuum
pump. It strikes me as being a bit overkill. Could I rely on just the
electric pulse pump if I took out the mechanical? Or is there some problem
with over pressure with these like I think I read somewhere?
