I'm scratching my head today. Just tried to do my fuel flow test on my nearly ready 9A. I have a FlyEFII boost pump with pre-filter coming out of my fuel selector. Goes to a firewall mounted Andair gascolator (Canadian requirement) then the engine driven pump followed by a red cube. I disconnected the fuel line at the servo inlet. Problem is that I am getting no fuel whatsoever as far as the open line. Nothing in the gascolator either. The boost pump is running, but makes irregular noises, something between a click and a clunk. I've got a gallon in each tank, same result on both, regardless of the position of my fuel selector. I tried initially at a 15 degree pitch (as is required for fuel flow tests in Canada) and then again after lowering the nose to ~level. I've got no leaks and can sump fuel out of both tanks.
I'm not sure what to look at now. I'll verify the orientation of the boost pump and the pre-filter, but I don't think that's the problem. Is it possible to wire those backwards?
Anyone have any insight? Maybe help identifying the noise I hear?
Thanks.
