  Gents:
  
 From this and other posts, I understand the need to turn on the boost pump
  ascending through 10,000, as well as the need to turn off the boost
  descending through 10,000 feet.  Thank you.
  
  My question is: How is a guy supposed to know that short of happening across
  it in an email?
  
  As I look at the Pilot Operating Handbook that I got with my kit, under the
  CRUISE checklist, item (4) says: "Low Boost -- as necessary for vapor
  suppression."
  
  Then, under the DESCENT checklist, item (2), it says:  "Low Boost -- OFF."
  
  What am I not reading that I should?  How is a guy supposed to know that 10K
  feet is the magic altitude for the boost pump if it doesn't say it in the
  checklist?
  
  I don't pick up my engine until next month.  Is additional operational
  information supplied with the engine?
  
  Thanks in Advance,

   Lancair Avionics incorporated an altitude reporting system that turns on
   the "fuel boost pump" caution light when I climb through 10500".  You
   should call them and see what they have.

   Anyway, is anyone having any luck with an altitude switch/light which
   acts as a reminder to turn the low boost pump on when climbing above
   10,000 feet and turn it off when decending below 10,000 feet?
