OK, so another big day...first gas.
Got 20 gal of 100LL in four 5-gal jerry cans. Took a bit to figure out how to transfer gas 2 gal at a time (into a couple 2 gal cans) to calibrate the left tank. Newfangled spring-loaded safety spouts have to pushed back by a tab bearing on the lip of the container or filler neck of the fillee. I put 2 gal cans against the outside of the hangar door, fill neck face out, keeping them from moving when the 5 gal jerry can bore down on the lip. Thirty pounds of gas is heavy!
The Dynon cap sender circuitry did register a change, but only 440 mV from dry to literally brim full. [The 2 gal pours weren't exactly NIST traceable measurements, so the last 2 of the 18 gals turned out to be >18 gal and a few drops (ahem) spilled on the floor.
OK, the big moment. A 5 gal can in place for the overflow line I rigged up--boost on!
15 sec, nothing.
30 sec, nada.
45 sec, no flow. Holy ****, I couldn't have wired the pump motor bass-akwards, could I have?
Despite a lunch break and searching the interwebs, I didn't find the apparent answer 'till after trying reverse polarity, which didn't work either.
Tune in next week for another exciting episode of "As the Avgas Flows".
