Depends on how it's failed, but it's likely it would, unless a one-way valve 
is jammed shut.  Be aware that if the failure is due to a diaphragm rupture, 
you ~may~ pump fuel into the crankcase.  This would be a bad thing.

I use my electric pump only rarely, as I installed it to solve a problem. 
Turns out I had a completely different problem.  If I planned to use it 
regularly, I think I'd opt for the complicated plumbing, or make the lines 
easy to swap.
