I just learned this one the hard way. Was bleeding my new clutch slave before installing the engine and, yes fluid starts draining out just behind the drivers side wheel well. Any painted surfaces in the wheel well I need to worry about? I cleaned everything I could find on the exterior.
Just so happened this plastic bin lid was sitting on a box below it all. Pulled the box out of the way and let it drain.
You will know this is about to happen when you start trying to pressure up your pressure bleeder and it's taking a while....
Here is the solution.... clamp the drain line with a small set of vise-grips, etc.
You can see my build thread linked in my signature. You can get a factory plug and the later 993 cap that is self venting to remove all that vent stuff.

I'm now in your camp of going to the later setup with the venting cap and doing away with this other venting system. Overly complicated.
I ordered all these parts and will pick them up today or tomorrow. I guess I just need to remove the fender liner and then pull out all that old, complicated plumbing..
My mechanic says that they experienced problems with the original 964 overfill system on some race cars, that under high g loadings, the brake fluid was syphoning off and out the drain. Hence, Porsche redesigned it. I won't pretend to be pushing the car that hard. : )

That's interesting. I thought it was primarily an environmental consideration. Apparently some folks didn't like the idea of brake fluid spewing out all over the roadway. Understandable, but now it will spew into your frunk? It may not be as environmentally conscious, but I think I prefer the original overflow reservoir.
