    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.

    Lot's of racers (read, probably all of them) don't bother with it in Canada either ... and we run in some cold ass temps (I've been on track while snowing!)

    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.

    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!

    Thanks for for any info.

    or just take a plug / bolt and seal up.
    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.

    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.
