Looking for an opinion / help. I am a new RV-6A owner - non-builder. So far have about 35 hours on the plane. 0-320 standard carb standard mags set-up. Last week-end I flew in a "missing man" formation for an amazing vet (another story). Anyway we were at low altitude for maybe 45 minutes waiting for the word to do the pass. Had the aux fuel pump on all the time (Facet automotive type). Later flew to another airport for gas. Upon takeoff engine almost quit during roll when throttle was full open. Also thought I smelled something hot! Shut it down, but could find nothing obviously wrong. Did another run-up with aux pump on and it almost quit again. Aux pump off, all seems OK. Is there any way one of these pumps could fail is such a way?
