Ford OBD-II Diagnostic Code PO 191

[Ford OBD-II Diagnostic Code PO 191]

2005 Ford V-10 E-450 Chassis. I routinely get the Code PO 191 when acceleration to highway speed after a brief engine turn-off. The code indicates "Fuel Pressure Sensor Circuit Performance". The engine has no driveability issues. All service items are current. Scanning guage clears the code.

I have a Class C motorhome on a Ford E-450 chassis. What valve extender can be used on the outside rear dual? I have 7" braided extenders on the inside dual. I have seen several solid extenders with various angles ie: 135 degrees etc.
