For a year I have been discussing with some fellow Lancair owners about
my engine fuel surge problem. N9070R IVP. Today it happened again and
for the first time I was able to look at the fuel pressure gage. The
pressure came down from 23.8 to 10psi.

Does that disqualify a momentarily lost of TURBO BOOST? The waste gate
and the comptroller?

 Every time it occurs I am on the left tank. It does not happens all the
time. I flew 30 hours from PR to Oregon and back with no problem at all.
Today was very fast before power came back.

  
It sounds to me like fuel contamination. Like if dirt comes off that
wing tank once in a while.

  
Your thoughts,
