[Roadsters] --> elect. fuel pumps, elect. fans

lines after long sits..."

If that's all you're using it for, wouldn't a
couple of squirts of starter fluid be easier/cheaper?

The 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.

An electric fuel pump
(used in parallel with the mechanical pump which I recently rebuilt but may
ultimately remove) is valuable in charging the fuel lines after long sits,
without needing to strain the electrical system and starter in order to motor
the engine to do so.
