Once the level of the fuel gets low, how does fuel go from the tank into the slosh cup? Are there holes in the bottom? I ask because I'm having fuel problems after recently sealing my tank. Since I only added a little over 2gallons, I suspect fuel may not be getting into the cup.

 

The slosh cup doesn't have any holes or other provision for fuel to enter. Add more fuel.

 

Okay, great! Thank you!
