Kevin,
What's up man. I have a 2002 SANTE. They basically are the same setup (you have automatic valves and I don't
). I just did this about 2 weeks ago. I didn't use the fly high sacs, but it would work the same either way. To be honest, I haven't even tried mine to see if it worked yet. Basically what I did is took the hose off before it got to the hard tank, put a T on it and put one hose to the hard tank and one to my fat sac. Then to empty, take the hose off right before it exits the boat and put a t on that with one going to your pump and one going where it is supposed to. then you can wire your pump to some toggle switches on the dash (if you have an extra button, you could use that). It is pretty easy once you get in there to get it to fill. I didn't wire mine in to empty, because I couldnt get the hose off (it is glued on). I have little cut outs that my pump hose goes out of so that is how I have it for now. I am hoping to try it out this weekend as well as take pictures of the work. If you want to wait until then, I will post the pics online and you can check it out. just email me and I will email the link.
