  Not really a trick but an IMPORTANT step.  It'll do two things. 
Bring pressure specs to new as well as almost insure against 
leaking at the halves union.  :-)
  There are 3 surfaces that need worked on.  You'll need a machined 
surface, glass or such flat area, some #4400 wet/dry sandpaper and 
a little oil.  You'll need to dress the bottom of the upper half.  It almost 
always has a groove/ring worn into most of the mating surface.  It 
doesn't have to be completely clean, about 85% to 90% groove free 
usually does it.  In other words only take it down as much as you need.
  There's a middle piece, about the size of a penny or nickel and about 
1/4" thick.   You'll need to do both sides but the side with two ridges 
will take very little.  The all-flat surface will have a ring in it and it's 
the 
one I was thinking of for the 90% cleanup.  oops.
  Rinse everything simply letting it drip and shake off, with WD-40 or 
diesel. Brakleen works better but the pintle/plunger needs to be 
lubed with WD or diesel.  Reassemble with just a touch of anti 
sieze on the threads of the upper half, to torque spec + 2 or 3
ft.lbs.  I add two ft.lbs in the event you need to use the upper 
half at some point to remove the injector.  That way it's tighter 
and removes the injector rather than coming apart.  :-)
