I have a small fuel pump that I used for a 2 cyl Onan generator that 
is a solenoid type unit with a built in transistor oscillator to drive
the plunger.  Only uses an amp or so at full flow...  it even has a pressure
regulator of sorts in that as the pressure builds up, the frequency increases
until it eventually stops at 5 or 6 PSI, until demand causes it to start 
again.  I still have this thing kicking around, if you want I'll see
if there's a manufacturers name / part number on it.  I just picked it
up at a local industrial supplier for around $30.  

Another suggestion:  I believe that Volkswagen Beetles used a small
electric pump to run the gas powered heater, this may be suitable for a 
small 2 cyl engine, although I have no idea what kind of pressure it puts
out...
