I can't finish this puzzle:
16A Excited by turn-over of fuel support (7) ?I?E?O?
20A Lover of a plunge in stream (8) ???A?O??
17D Go back for sunset ceremony (7) ?E???A?
Thanks for the help. I thought I'd be able to get 19A after the entry of cross clues. But I can't: Caught a piranha devouring animal (5) ?A?I? What could it be?
