| Also, any device driven by the engine reduces (albeit by a tiny ammount) 
power.  A good electric pump will have a minimal parts count and is less 
likely to deliver fuel to the bowl in squirts (a regulator will help 
with both manual and electric pumps)  On the plus side, a mechanical 
pump will deliver more fuel at higher RPM, where it is needed, unlike 
many electric ones.
