I had that problem on a friends 22FZB I was testing Nick. For 40 years this car and two others have had this pipe arrangement with no problems but on this occasion it chose to air lock. I stripped the taps and inspected them and the tank and found everything OK and reassembled everything except the float chamber top and opened the fuel tap. Every time I've done this before I'd get a fountain out of the float chamber, not this time nothing so I blew into the tank filler and after a load of bubbles we had the fountain. Needless to say the pipe run is being altered.
