Hey AllNow that the warmer weather is coming to Mn. I can work with the hangar door open.I get a constant stream of visitors stopping by to chew the fat. It's anotherside benefit of having a Piet.Anyway, today a A&P stopped by and made a couple of comments I thought worth passingon. He commented first on my placement of the gascolator on the firewall.He suggested that I move it so that at rest it was lower that the carb bowlat rest, to be the lowest point in the system. Also, he suggested to do a fuelflow test to verify that at rest, the fuel line provides a flow of 10 gal/hr.with minimum usable fuel remaining in the tank to simulate adequate flow fora go around. Also an extended test of the flow to verify adequate ventingof the tank.Just a couple of points I don't recall having seen on the list.Dick ________________________________________________________________________________

Dick It is a good idea to do your flow test at max climb angle. If you everended up making a go around after a missed approach with low tanks it mightbe the factor that saves your #####.John-----Original Message-----

Good points, Dick.Another point to mention when choosing a spot to mount the gascolator on thefirewall - while it needs to be lower than the carb float chamber so it isthe fuel system's lowest point, it also should NOT be the lowest point onthe firewall. There should be structure lower than the gascolator so thatif a really bad landing wipes the gear off, the gascolator is not the pointthat the sliding fuselage is resting upon. Otherwise, it will be destroyedin a hurry and all that fuel will be deposited right where the friction hasgotten things really hot. Not good, but spectacular.Jack -----Original Message-----
