I don't see a question, but are you sure the new sensor is compatible with your analog gage?

Question would be , does the scan gauge get it's info from the same sensor/sender as the gauge , or does the engine have two , one that reports to the ECM where the Scan Gauge gets it's reading , and a second that only operates the gauge. 
Was it a low Scan Gauge reading that you replaced the sender to correct?
Or a low dash gauge reading, that didn't agree with the Scan Gauge?

My wiring diagram shows 2 elements within the sensor. 3 pins on connector:
One appears to go to a analog gauge pin (C),
Other goes to PCM pin (B) ect signal.
PCM low ref. pin (A)

In 2001, a Workhorse chassis could be one of their own design, or one constructed from leftover Chevrolet P-30 components. If yours has the Chevrolet dashboard, I have found on my two examples that the coolant temperature gauges on these are notoriously inaccurate by reading too low, and a scangauge is really a better indicator of the coolant temperature.
