Fuel probe modification

[Rick524]

I've read about others having problems with their Princeton fuel probes. So before
I mounted my fuel tank in the plane, I thought I'd try it out on the bench. I had
no luck getting it working right. I came up with a fix that works well.

I had another fuel probe made by Centroid. (cgfp-12a-12v-0/5v-3bndbl-sidewires-avgas).
I separated the probe from the Centroid electronic module and connected
it to the Princeton probe. Then mounted the module on a bracket that is held in place
by the oops fitting nut. The readings are very stable and repeatable. The Centroid
calibrates easily by holding a small magnet up to the module when power is first applied.
This gives you your empty reading, and the other setpoints are done in the Enigma.
