IMHO, if you want to just monitor one or the other, return is better.

Seems like having two fuel flow sensors and indications (FF being burned, and FF being returned) is a really important "discovery" or "insight" for discovering failing fuel pumps or accumulation of debris. I'd never have thought of monitoring "return" FF until this pump failure experience came up.

Perry,
Kelly is right. one of my walbo pumps just went bad but it was very intermittent. It was a lot more obvious by watching the fuel flow.
Ed lists all the other possible causes.
