Fuel Pressure Sensor

[jimnance]

The '03 H. O. has a fuel pressure sensor. My buddy at Dodge does not recall a sensor in earlier models. He thinks it may be an attempt to prevent pump failure by detecting low pressure.



Still looking into this as the sensor may have another function.

it does indeed have a fuel pressure sensor. but i believe it is measuring the high pressure side [±25,000psi] this will most likely be used in early power boxes [like the early duramax boxes - upping the rail pressure]
