Yes and no. I originally set it for 1500 cause I have a 1.5l tank but that set the alarm off about halfway thru my flight so I played with it till I got it to the point where it goes off after my normally flight with 2 go around which leaves about enough fuel for a gear pass and 2 more go arounds It consistently comes down at the same point. What I don't know is if different size pumps change the values this is on a k45
