RE: hose #14 - read up on carb icing. 999 out of 1000 times, it's not a problem, but go for a drive on a wet/cold day and you might have problems. Just sayin'
OP - you are in Cali, so it's likely not a problem. Lots of racers in the mid-west don't bother with it either.

We also offer a couple of nifty bolt on solution for the OBD-2 guys who don't have a pipe there like the OBD-I heads & for S54 engines as well.

OBD2 to OBD1 Conversion Coolant Hose Adapter for E36 E30 M50 M52 S52 Engines <---- Link
OBD2 to OBD1 Conversion Coolant Hose Adapter for E36 E30 M50 M52 S52 Engines replaces the metal pipe from the OBD2 engines with a hose adapter that allows the installation of a normal OBD-I coolant hose. This is useful when converting an OBD-II Engine to OBD-I or when swapping 3.2L or 2.8L engines into a car which has been converted to OBD-I like an E30. It is also useful when using an OBD-II head on an OBD-I car.
The simple kit comes complete with necessary 2 O-rings, extended bolt, Nylon Lock Nut & washers to make this a quick install. No need to wait! It is also completely reversible!

Sorry for bumping an old thread, I didn't want to start a new one.
For those of you that have used the port for hose #14 for an aftermarket temp sending unit like eye145 describes, what is needed to attach the sending unit to that port? Do i need an adapter? Thread the port so the sending unit screw into it? I'm trying to plan ahead and do this on a tight schedule so I don't have time to figure it out once I take the manifold off.
Buy this and put it in.

I tried to make and adapter. I ended up just buying this. Quick and easy.
Also you can get to it pretty easily with the manifold on.
Thanks! I don't have the luxury of tearing the car down, figuring it out, then finish later this time around. I stopped by my friends at Delta V Motorsports and thanks to a spare S52 laying around I confirmed that the plug is M12x1.5 and the adapter you linked is exactly what I plan on ordering.
Does anyone know where a detailed diagram of engine hoses for a 95 525i ?
Looking for part name/number so I can order the correct one.
