Can I get more hopper capacity for the M680 Mortar Pump?

Yes, the 25 gallon hopper 287987 can be connected by raising the mortar pump sprayer off of the ground 1.5 inches (thickness of a 2x4) and connecting a cam and groove fitting (reference Dixon 200-D-AL) and a cam and groove elbow 16V510 between the hopper and the pump inlet.

Things to consider:

1. Always keep the hopper clean, scrape side walls of the hopper before adding another mixed kit of material.
2. Use caution with 2K materials
3. Do not exceed material cure times
