 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?
