http://spirit.eaa.org/apps/magazines/ea ... 05.pdfI've attached a good fuel system article by Tony Bingelis but if you have the books by Tony Bingelis he will show you how to installa flawless fuel system and also show you how to exactly calculate how much fuel you have that is usable an unusable in your system.I have a 17 gallon nose tank and I did the prescribed static fuel flow measurements for my Piet setup on a earthen barn ramp that wasin the back of an old farmhouse I was renting while building.The barn ramp simulated my plane at a climb angle and the fuel flow was measured into a Rubbermaid iced-tea container which hadboth ml and oz graduations on it. That, a stopwatch on my watch (now cell phone stop watches work great) and some fuel and I all I needed.The method Bingelis suggests puts the plane in a climb attitude and his calculations account for a full-power climb out situation.Those four books are worth their weight in platinum or gold (depending on which is higher!)Best $89 you'll ever spend on your Pietenpol!https://www.eaa.org/en/eaa-shop/homebui ... t-of-4Mike C.Ohio________________________________________________________________________________

Mike,That was a timely post that I put aside until I had time to read it. I amrebuilding a Baby Ace that suffered a bit in an off-field dead sticklanding. While flushing the tank, and checking for residual contamination, Inoticed a very poor rate of fuel flow. The pictures are self explanatory.Gary BootheNX308MB
