Any links or pics appreciated. Background: I've decided to change the location of my fuel flow unit from the tunnel to between the fuel controller and the spider. I've seen a few pictures of other installations but I know I've seen some I can't find at the moment. I've gotten quite comfortable with the tunnel installation. There's no doubt that it's a bit inaccurate with the boost pump on but that's not really a problem. However, the folks at Airflow pointed out 2 other issues that I'm in fact experiencing: 1) Fuel flow readings fluctuate a bit, as recorded by my GRT system. It's only plus/minus .2GPH but it limits the accuracy of my nozzle tuning efforts. I'm tuned up pretty good right now but I'd like to improve it a bit more. 2) During full power climbs my fuel pressure drops a bit below where it should and that causes me to turn on my boost pump for short periods of time midway up during my climb outs. I can't recite the exact reasons for that as described by Don Rivera at Airflow, but it's related to the restriction of flow sensor and it's location between the tank and the engine driven fuel pump. As I understand it, it's best to have as few restrictions as possible upstream of the fuel pump. And having inadequate fuel pressure during full power operations is undesirable.

I used Adel clamps to attach a 2X2" aluminum angle that the floscan mounts on so it's between the mechanical pump and the fuel servo. The reason I did it that way is I've installed an iSTART system that injects fuel into the air intake past the fuel servo. See it in use here: http://istartair.com/. If I placed the floscan between the servo and spider the fuel usage wouldn't be as accurate as I want. You reminded me to take pictures which I'll do after Sun -n-Fun.
