No problems with stock position
After reading this post and report, I checked a couple long-flight logs for which I have data downloaded from my AFS. I don't see any such sags in fuel psi during cruise, and my red cube is in the tunnel at the stock location. I usually fly pretty high and my tunnel never gets hot, even in hot weather at low altitudes, but I will keep an eye on it. I do have my sample rate set at 5 sec, so I might increase it to 1/sec and check again, but I've not seen any of the other symptoms Bob mentions, like inability to run lean of peak or engine roughness. I've consistently operated on long flights at 9.5-10.5 gph, 30-90 deg LOP without engine roughness. I have a similar set up to Bob's except no gascolators in the wings, Aerosport Power IO540 engine and Silverhawk injection system. Thanks for the research and diligence, Bob, something for us to keep an eye on.
