another question. vent lines?

hate to keep starting new threads here... anyways, I threw a b pipe and msd enhancer on my ski last yr towards the very end of the season. kind of did a half job on it just to try it out and now that its winter I am trying to sort things out a bit, get rid of the stuff I don't need, and clean up the engine compartment, so bear with me:

1. There are two vent lines that run up into the handlepole and end right at the base of it, by the rubber boot....

One, if I recall correctly attached to the old/stock exhaust system?? Am I correct in saying that, or am I missing where that should be hooked up?

The other appears to be a water/fuel separator. Are these worth keeping on the ski, and can someone explain to me how it actually functions when the pickup is on the top of the tank?

2. On the stock head, there used be a small line (prob 1/8 inch or so) that ran from the head into the "stinger" if you will.... They provided a small vinyl cap to go on there, but I melted and/or pressurized a couple right off of it, even with a zip tie on. Is there a better way to cap that thing?

3. On my MSD enhancer, I left it set where it came from the factory... is it worth cranking the rpms to max it out, or am I asking for longevity issues? I'd rather have a ski that runs reliably for a few years then to be replacing it early due to over revving it... rarely do I do much WOT end anyways. thoughts?

One vent line is for the tank and the other is for the battery. The little plastic capsule with tiny holes keeps water out of the vent line unless you sub it deep. The water seperator in the hull does a good job but must be emptied often. If you like to sub then check the bottom of the tank for water because it will make a mess of your carbs. Many people like to leave the vent inside the hull, which is fine until their ski blows up. The small nipple on the head can be filled with RTV or epoxy, or put a small screw in it and slide a short peice of primer hose over it. Your MSD can be turned down if anything. No need to rev much over peak smooth water rpm unless your going fast on rough water.

The tank vent hose will get some water in it if you sub the ski or even turn it upside down in the water. The seperator is air/water not fuel/water, it catches the water before it gets to the tank. It is common for fuel to get pushed up into it from sloshing and venting.
