Fuel guage values. Lapuwali?, Here we go again..... Options

[Dr Evil]

So I am in the process of putting my VDO fuel gauge in. I decided to call NH speedo, and PA speedo again to see what they had to say for values. I did this because last time I called them they told me 10-180 ohm empty-full. This was disputed by lapuwali (IIRC) when he said it was 0-90 ohm and I believed that he had tried it. I believed what he had to say, but was confused by the info that I had gotten from the "pros". Well, when I called today I got even wackier numbers. NH speedo told me that I needed a gauge that went from 67-1.8 ohms empty to full. WTF! PA speedo told me that thier tech had gone home for the day and they couldn't tell me anything. Both places offered to calibrate the new gauge for me for as little as $65. One guy said that all they would have to do is insert a POT to change the values.....I don't think so. If the full value is now the low one and the empty the high, you cant change them by using a POT. So basically I am back where I started: No real clue.

Lapuwalli, did you get it to work with a 0-90 ohm? Anyone else? I am trying to add to the information so someone can sift throught hte confusion later on.
