Mike,
Pantera Performance in Colorado sells a Centroid adapter for the Pantera's fuel tank. Unfortunately, there's no provision for a fuel pick-up, so you need to draw fuel from somewhere else. Accordingly, I replaced the drain plug on the bottom of the tank with a high flow banjo fitting from BAT in Florida. I suppose an adapter could be machined that incorporates a fuel pick-up but I decided to go with the PPC adapter.
Centroid has had a few Pantera owners and vendors provide them with calibration data. Centroid warned me that the specs they have been provided with differed quite a bit, so they were the most comfortable if I provided my own calibration specs.
The other thing they warned me about was, due to the design of the Pantera's fuel level gauge, it is sensitive to input voltage. It will read differently with the engine "off" and the engine "running". They said the Veglia gauge works fine with +6V, so their advice was to supply power with a +6V voltage regulator. That way, it always reads the same, as long as the car's battery/alternator voltage is higher than +6 volts. The sending unit then needs to be calibrated for +6V, for the gauge to read accurately.
