    I ask the same question Wakemikey askes. I love your setup. I would recommend changing the connectors on the wiring from twistlocks to solder and heatshrink. Not trying to bash, just a hint.

    That is going to be one of my to-do's, made a little hickup when installing... I would recommend extending the wires on the tsunami's before you screw them into the manifold. They are short and difficult to reach after being attached to the manifold. If I would have done this I could have soldered them on. Trying to heatshrink them would have been difficult, so I had to go with the twistlocks. If I ever get motivated again I will remove them and heatshrink them on. For now the twistlocks will have to do. Solder and heatshrink definitely is a better way to go.

    I guess I meant what keeps water from draining out the drain pumps, not the fill pumps. Assuming all pumps are turned off.

    Which twistlocks are you referring to? Not fly high quick connects I don't think? I have not had any trouble with them...

    I have the same question. What keeps water from going out the drain pumps, or does it still function the same as the factory setup? If too much pressure is put on the bags the water is forced out the drain pump to relieve the pressure. I've got three bags tied together now on the same fill pump (stock) and the only way I can get them to all fill completely is to put a manual ball valve on the the empty line to the pressure can build and equalize the water in all three bags otherwise it just flows through the empty pump and does so every time you throttle on.. I just have to remember to keep my eye on the bags when filling.

    I believe the vented loops are used by other boat companies such as malibu. I know a couple of guys that have bu's and their center compartment will fill on it's own sometimes. I hope this system works as I would like to do the same modification.

    I tried to use a vented loop in my system with a reversable pump. Doesn't work so good. Water squirts out the little valve when you try and reverse hehe.

    Nothing has changed from the stock drain pumps and lines. I have not looked into what pump Supra is using to drain the sacs, I know it is aerator style, and they mounted it lower than the bags to help it drain when turned on. I do know if you overfill the bags it will start to dump water out the drain hole.

    Sorry I could not answer your question better, but like I said, I have made no mod's to the current drain system from the factory other than installing the no-kink 3/4" line replacing the stock black line.

    The twistlocks I was referring to was the yellow electrical connectors.

    Yes, nothing has changed from the factory drain system, it will push water out when its full. I usually let it fill until water is coming out the drain hole. Especially since there are no gauges!

As I mentioned in my write up the Tsunamis will not stop water flow, the vented loops are there to prevent water from entering the bags while driving the boat. If you do not grind off the scupper on the intake it will force water into the system and the vented loops will not be able to hold back the pressure and your bags will fill up. This is why Supra was using the sprinkler valves, to stop water from entering the bags.

    The only other option if you choose to leave the scupper on the intake is to manually turn off your system with the ball valve when you are not using it. I did not want to have to lift the seat up/cooler every time I wanted to fill the system and then have to turn it back off after the bags were full.
    thanks...don't know whenI'll get this far, but you're install looks amazing and I would assume works as well! The brass Tee's reminded me of a bathroom tub I installed!!!!

    Okay I was just curious about the drains because many aerator systems use an electronic gate valve to keep everything from draining back out. If you find a good way to eliminate that and the system is simplified.

    Does their aerator system drain out the overflow/vent holes as opposed to the fill holes on bottom of boat? How do you like that?

    Yes if the bag over fills it will drain out the exit hole on the side of the boat. I usually just keep them on fill until I see the water coming out and know its time to shut off the pumps.
