[DeTomaso] Ohm range of Veglia fuel sender

This is from my notes where I tested my gauges on the kitchen table.    I
think I did a post with pics of setup on PI board

All,

 

I have researched and found there are posts that say the Veglia fuel sender
is zero ohms when full, and 200 ohms when empty.

 

I have also researched and found there are posts that say the Veglia fuel
sender is zero ohms when full, and 340 ohms when empty. 

 

Anyone know which is correct? 

 

Anyone sure there was not a design change somewhere during production?

 

There are now numerous little black boxes, some as cheap as $40 and others
well over $100. They all purport to allow custom calibration for three or
five points, determined while bench testing sender and gauge through the
little black box. 

 

Before I get into selecting a little black box I figured I should try to
confirm what the Veglia ohm range actually is. 

 

I am seeking to provide a halfway accurate signal to a VDO gauge with a
range of 10 to 184 ohms. 

 

Anyone by chance already solve that equation? 

 

Any and all wisdom appreciated. 

 

TIA,

 

Larry
