If any lister has a spare unused P/N 3010018 Oil Pressure Transducer, I would be interested in borrowing it to further confirm the problem. A new sender fetches a princely sum of $400, so I want to be sure. Thanks in advance.

Dear Listers, I installed Princeton 18-5B-5S Fuel Senders in the left and right fuel tanks with Proseal (see attached). Last week I installed the wings permanently and today I torqued all of the fuel lines from the wings to the fuselage. I got 21 gallons in 5.25 gallon increments ready to calibrate the 5-set point Princeton probes today. They both powered up fine and started flashing the left light indicating the Empty set point. I pushed the button once per the calibration instructions to go to the 1/4 level. Instead of getting the #2 led flashing, I get the all three LEDs flashing sequence indicating that probe "Can't be calibrated"!!! From the installation manual: CAL Error (three flashing LEDs) - The probe failed to calibrate. Possible causes: water in the tank (NO), inner brass rod is shorted to the outside aluminum tube (PROBABLY), Alcohol in the fuel (NO), trying to calibrate full first instead of empty (NO), or the probe electronics have failed (MAYBE)." Yeah, you read all that right. The best part of this story is that I Prosealed these babies in, installed the wings, and now discover that both probes are defective or what even. How can this fricken be? Its too late in the game for this. Replacing these stupid probes is going to be a major pain not to mention the fact that likelihood of leaks are now going to be high. I just can't believe it. This is so frustrating. Why didn't the manual advise to check this long before now? Like before they were installed, during installation, and right after installation before the Proseal cured? Oh, did I mention BOTH are bad? How can this be... How disheartening. Please tell me I'm just mis-reading the calibration instructions...? I'm going to go out on a limb here and say avoid these piles of garbage...
