View Full Version : Plumbing outback LS ballast

08-31-2007, 12:40 AM
Hello, sweet forum you guys got going here. I bought my first boat this summer, an '03 outback ls. It has the tank under the rear seat, however its not plumbed. I searched and found lots of info on v's and plumbing for 3 tanks, etc.

Does anyone have a pic of how this tank is plumbed on their boat? The tank has 3 threaded inputs, two on top and one on the bottom. Do you run an input pump on top, and a second output pump also on top?

Are you able to buy the switches from moomba so it looks clean?

Thanks for any help!

Im making my own version based on their design for my LSV, but I bet they have something for you.

I checked that out last night. I just went to the hard ware store and about a bunch of stuff so I'm going to see what I come up with.

Not sure if you are still around on the forum... but if you are, do you happen to remember what size those connections were that needed plumbing? I am about to order a cap for my top one and a vent but i'm not sure of the size.
