Jeff, what's going on the pump?
The larger little giant pumps are great pumps. Solid.
The VMC Series is a 1-gallon coolant unit with a pump included. The coolant liquids can adjust to any amount or completely shut off without hurting the motor.

The 5-Series are compact and robust utility pumps for a wide range of uses. These models are ideal where water removal, transfer, or circulation is necessary.

I have 2 of these. Unfortunately I destroyed one... my fault, was going to rebuild it, and lost some of the parts, and let the oil out all over the place.
But these will handle a lot... or go dedicated like above.
