  Most fuel line leaks that cause starting or power problems,  usually 
don't leak fuel, at least for a while.
  With a mist of fuel on the pump, it sounds like high  pressure.  Not 
sure if the distributor to body o-ring is high pressure but don't  think 
it is, which would lead me to look at the 4 high pressure lines for  a 
slightly loose fitting or crack or such (missing brackets usually cause  
this.)

  Those things usually leak around the plastic thingy on top.   Only 
cure I've found is replacing the stupid thing.  Dad's had a few K on  
it and died on the highway, sub freezing temps.  Once we figured it  
out, we put an A2 filter on it and ran the return back to the pump and  
eliminated the cycle back/fuel heat, plastic thingy.

  Surprisingly, even at those temps, they often need a second or two  of 
glow time to start/start well.  I recently had to crank and crank to  start 
mine and an independent shop told me it sounded EXACTLY like glow 
plugs.  It was in the 80's roughly, at that time.
