In post #3 (http://fordfusionhyb...l-tank/?p=90792) GrySql provided a detailed description of what happens when the Fuel Pump Assembly (FP) Reservoir runs dry. I suspect GrySql found this in a shop manual or similar resource.
Are you saying this is what happens to our FFHs everytime it cycles between the ICE and EV? I could be wrong, but I suspect that is not even close to what happens during normal driving and to characterize the normal cycling between ICE and EV the same as running the gas tank dry would be incorrect.
I do have the shop manual and the only thing that I see as different mechanically is the fuel in the fuel line isn't pressurized because fuel pump can't pump air. From the injectors forward it would appear to be the same.
Paul PS BTW last I checked there has been 211 views to this thread so far, apparently there are quiet a few curious about their tank size.
