I bought one of those pumps to dewater the pond as we were renovating it last year. Tips:

1)You can use 4" pvc pipe (with adapters) to connect a flex hose to the output of the pump and run it as long as you want. Bigger outlet pipe = less restrictin = more flow.
2) I used a 6 gallon outboard motor gas tank instead of the tank on the pump.
3) After the first 8 hr. of run time, I drained the oil and refilled with synthetic oil
4) Use an inner tube and float the intake screen/intake hose to keep from sucking a bunch of sand/junk into the pump.
5)Make sure that you have a solid base to set the vibrating shaking pump on or it might end up in the creek!
