That '10 3.6 F-car has a GDI fuel system. There's a module-driven, PWM-actuated in-tank pump for the low pressure side, and a high-pressure engine-driven mechanical pump. There are three-wire, 5V fuel pressure sensors for both sides, which means a scan tool will read both high- and low-side pressures.

I have not known that particular application to be "horrible about fuel pumps" at all. I think that, being PWM-driven rather than running full-tilt all the time, the electric in-tank fuel pump will probably last longer than expected.

Do you have particular examples of this engine or platform that would support your opinion?
