Not in terms of capacity, 6.5 feet of hose in the entire system. I swear, leave it to Toyota to do something so complex in such a simple way. I have my front sack plumbed like this, one pump through another. it works well.
It allows for fill and drain of both tanks or drain of either tank. No checkvalves or siphoning. What you save in hose you spend in solenoid valves, they can be had for around 100$ ea. These are small, .5 in so the system is slow. I might swap in a bigger fill pump, possibly bigger solenoids. I could make an identical system with two tanks in back....
The pumps are located under the forward floor panel, forward of the gas tank. There is another blue solenoid valve to the port (left) side under the floor panel. The third pump is the bilge pump. The left Rule 1100 has the thru hull and brass seacock.
I'm not even going to mess with trying to hook into this ballast system, though I may plumb the overflow into front sacks. I'm bummed to see that there is less room under the seats than there is in my Epic22:( Not sure if the bow sack is worth it
