On the side of these fuel pumps on the edge of one of the black plastic sections, there is a protruding tab with an arrow and the arrow has a "up" printed by it,the arrow should point up when mounted correctly. I have always assumed that these pumps must be positioned with this correct orientation to work right. I worked on a '89 Evinrude 15 hp i just got.It was mounted wrong,the arrow was pointing down. The pump worked fine.
Is this a big deal or not to follow the arrows mounting direction? Normally i do as i'm told..kinda
Thanks, Jim PSB
