Fuel Pump Return line

----------
Fuel Line return - ancient history

Hilborn type mechanical fuel injection had solution 30 years ago
Used a small (1 to 2 gallon) holding tank mounted higher than
mechanical pump (made it self priming).  Return fuel went to 
holding tank (may be referred to as make up tank also).  Fuel was
fed by electric pump from main tank to holding tank.  Used modified
holly 4 barrel float bowl to regulate level of fuel in make up tank.
Same Idea would work very well.  Make-up fuel = fuel actually
used by engine.  Could use off shelf carborated engine after market
fuel economy measuring system. 1 to 2 gallons (like original) avoids
problems of
directly returning to pump.  Works on engines up to 3000+ hp so
can't be all bad.

Now if anybody knows about where I can get pulsed injectors that will
work with liquid propane?
