4" Hose Adapter with Filter
This filter is to be installed from inside the Water Truck tank.
Where you want to put your suction output, cut a hole 4-1/2" dia.
With the filter side up, introduce the hose adapter end into the hole, then waterproof weld all around the square plate to the surface of the tank.
This way any piece larger than 1inch wont go into the pump and damage.
