<<I don't know this for sure, but if you have a rough-running engine on a hot day, you might turn on the boost pump and see if it goes away....

Anyone out there with experience in hot weather with boost pumps?

- Rob Wolf >>

I had an experience recently in extremely hot weather (South Carolina, 98 degrees). My engine just quit while waiting to take the active runway, after taxiing quite a ways. It had been running rough . I restarted it, ran it up again, everything fine, so I took off and remained in the pattern. It hiccupped once on crosswind, and I mentioned it to Don Rivera (AirFlow Performance, I had gone to Spartanburg to have balanced fuel injectors installed), and he suggested I run the boost pump to prevent vapor-lock on taxi and climbout, especially in hot weather. Since I have started doing just that, I've had no further episodes of rough running or hiccupping on climbout even though I've been in the same temperature several times.

OBTW, the balanced injectors are saving me over a gallon per hour in cruise. I highly recommend them.
