I don't believe Tony was criticizing your post directly, only trying to point out and reemphasize the "danger" of
assuming that if fuel comes from the FA when the hose is removed that the FA is bad.
There was quite a thread a few years back where Tony clearly demonstrated that the bottom hose and bottom of the FA will contain fuel due to the flow of fuel through the common return lines back to the tank. It was an attempt to convince people not to just replace an expensive part without properly testing it. Simply removing the bottom hose and witnessing fuel running out is
not a definitive test.
Yes, you were lucky but you had already eliminated the other obvious suspects so your FA was now at the forefront, even though it had been replaced by the PO. Your takeaway, IMO, should be that the FA needs to be properly tested before replacement and that simply removing the hose and observing fuel is not the test to use. Remember, all these threads help future users and someone who, like you, isn't quite clear after reading other threads, may come across this one and have more clarity.
