Can I pump from one truck to another?Question:I have a 3,500-gallon vacuum truck and a 1,500-gallon vacuum truck. I always fill the big truck to go and dump. Can I pump straight out of the outlet on the small truck right into the big truck without hurting the pump or anything else on the trucks? I’ve been dumping the small truck into a holding tank and then pumping out the holding tank with the big truck, but it just takes extra time and work. Answers: It’s no problem, as long as you put your small truck’s vacuum pump in neutral
