I was able to solve all my deep water and splash problems by first using a peice of foam about 1 1/2" wide X 1" thick X about20" long, and placing it between the tank and the plastic just behind the gas fill nozzel and ahead of the two intake tubes. This keeps the high speed water crossings under control. (water likes to "ram" it's self under the front fenders and up over the tank.
Second, I took the stock (96 SP 500) PVT discharge tube off and pitched it in the woods. I went to the parts store (parts store, not a auto store that sells spark plugs and plastic crome wheel covers with a high school kid behind the counter asking you to explane what a set of points are) and look over their radiator hoses, find one or two that will combine to make the correct curve out of the PVT and up the left side of your gas tank (again, under the plastic outter shell)and curve at a sharp 90 dgree at the top, (right at the top of the tank) This sounds like it might be a lot of work but it really is not. I used two hoses, and used a thin 2" muffler sleve to couple them together with hose clamps, you can't see any of it except the hose that connects to the PVT and that looks stock. This mod. was one of the best I'v done, it works great, and lets the PVT breath just fine.
The hose and sleve are colapsed to about half their diamitor to form an ovel, this allows it to fit up between the tank and plastic.
So now you have some more food for thought.
