I took the hard tanks out of my 2004 LSV and put 20x20x50 sacs in their place. My sacs had 4 ports each, so I was able to use the 3 hoses that ran to each factory tank and plumb the sacs in the same fashion as each hard tank. I simply bought some 3/4" hose and extended the fill, drain, and overflow lines and ran them to each sac. I am still using the factory pumps, although it takes a few extra minutes to fill each sac compared to the time it took to fill the hard tanks. I found (as has everyone else who has done this mod) that the sacs will self-drain down through the drain lines or back through the fill lines and push the water past the pumps. So you need to install some sort of valve that will stop this effect. A cheap and easy way to do this is put a $2 ball valve in-line in each fill and drain line and just open and close the appropriate valve each time you fill/empty the sacs. I wanted a totally automatic system, so I installed a cheap one-way cheack valve in the fill lines, but the drain lines were more tricky. A one-way valve would not work in this situation, so I found some $60 electronically actuated valves that I put in-line and spliced the wiring into the drain pumps on each side. This has worked great, and the system is totally automatic. Works just like the factory hard tanks did. I have also added about 450 pounds of lead under the dash, observer's compartment, and side seats to balance out some forward weight. The wake is fantastic with the extra weight.
