Whatever floats your boat. A can of starter fluid is like $3.95, no add'l
plumbing, wiring, etc.

With respect,
neither, IMHO.  It's a $30 fuel pump and a slick installation.

electric fan benefit is primarily in limiting fan thrust/drag power loss at
speeds when forward motion alone provides sufficient cooling air flow (no
thermal clutch here), cycles to cool the engine on a thermostatic basis,
cycles after shut down, and I suppose eliminates some water pump bearing wear
associated withfan thrust axial loading at all speeds.  Noise is much lower at
high RPMs as well.

the electrical system and starter in order to motor the engine to do so.
