Do they both route the same way (up or down)?
Both lines come from top of tank one driver side and one pass side. They do a 90 from the top over about 6" then 90 and down and out under the rig.
I have been doing some more research on the forum. It looks like some people have said that the vent/overflow hose is too far in the tank and causing it to siphon the water out. Now this has been on different rigs maybe that could be the problem. I would have to find out what it takes to remove the hose and then reinstall new clips on the lines.
