What fan is this?, and a fuel line rant Options

[blaize]

Ok I have just finished throwing my engine together and with luck it will go in this weekend. My old cooling fan was missing damn near half its blades so I got a used one that is perfect, but it has no TDC mark. this is no big problem really, I just made one with nail polish. It is not perfect of course as I was looking down the plug hole to find TDC but it will have to do. here is the question though. it only had one mark on it, a red line that given its placment I assume is the full advance mark. the engine is a 2.0 but what fan is this? are they all the same? exactly what is that mark?

Since the engine is out I have been cleaning things up in its hole, repainting it, new wiring, and I decided to replace the fuel lines. All the older techs at work (Porsche dealer) tell me they saw tons of engine fires in 914's way back when. but I looked and THE F*CKING TUNNEL LINES ARE PLASTIC!!! what on earth is that all about. Crazy Nazi bastards. Anyone ever have any trouble with these lines, or am I overreacting? the car is now on carbs (Don't start P.O. did it) so the press. will be lower. any input?
