Thanks, Rob. My Red Cube is in the tunnel per plans. I've been wrenching in there replacing fuel lines from each tank to the Andair valve with nicer Holley filters under the seats to replace the little Jegs filters I inherited with the kit. It's possible I bumped a connection on the Cube. Will pull inspection cover and take a look around. If the Cube is T.U. this would be an opportune time to install the next one between the servo and spider. Seems odd for a Cube to quit with so little time on it (<10 hrs) but I know they have a reputation for throwing in the towel at random times. Is there a recommended protocol for troubleshooting an apparently dead flow transducer?
