I was wondering, but probably wont build it, not any time soon anyway. if you had an fx5 with its 25mm hoses, and the pump died could you plumb a 20000 lph pump in line and get super flow out of it. using some thing like the pump in the link.it does say its usable in-line not sure how but that's not really the point. what are people's thoughts on this.
