Re Propane injectors

     Guess you don't want a pipe to burst while you are leaning over it, or 
     you may just loose a few body parts.

Yes:
     
But diesel injection needs around 25,000 psi of fuel pressure, so the 
injector is a plunger piston pump that is operated off a lobe of the cam 
shaft (twice as wide as the one that opens the valves).  The electric 
solenoid is a bypass port that when ON blocks the outlet of the injector 
'pump' and forces it into the cylinder.  When OFF the flow returns to the 
fuel tank.
