Finally made the flight from AZ to TX in my 14-13-2. Long story but 4 shops and about $35K later the bird is in my hangar.
En-route at cruise at about 7500 ft, noticed something strange with fuel pressure. Or right tank full, newly rebuilt gauge showed only 2lbs pressure at first. When tank got to about half full, that moved up to 4lb. Left tank started at 4 and stayed at 4. With aux pump, we were at 5 either tank as checked at runup, or at switchover. What would account for that? Engine ran without a hiccup on either tank. But I do wonder, does the change in pressure affect the mixture setting? We never really checked that. You would think with more pressure the mixture might be richer?
