power steering reservoir leak/cleanup/replacement

Ok, adventure #2 in just-acquired-'95-355-GTB World. Looks like some joker failed to secure the power steering cap properly (I never checked it until tonight, when I noticed spatters on the deck lid) and I've been spitting fluid for at least some of the ~100 miles I've driven in the past two weeks. There is even some pooling on the garage floor. Photo here:

…at least I think that's ATF fluid - it's brownish-red now after probably getting a good singeing on the block during its way down. (If it's mixed with crankcase-leaked motor oil, I'd rather not talk about that right now.)

I found the excellent reservoir replacement thread - http://www.ferrarichat.com/forum/348-355-sponsored-bradan/292079-how-update-power-steering-tank-355-a.html - and will attempt to take care of that in good order, since I've got a '95 with the o.g. giant cap reservoir.

Question for the forum: am I at a serious fire risk here and should avoid driving until I can get the coolant/atf tanks out of the way and clean up the block as best I can? Or has most of the risk literally drained away since my last drive 2 nights ago? The cap is properly sealed now and I haven't driven the car super-hard at all. Mostly loafing about Seattle with a few spirited interstate runs.

I should've known when it seemed like the whole engine smelled slightly sweet as it was cooling down that something wasn't right…

 

Yep, found that DIY thread before and plan to tackle the work, like i mentioned. Thanks for confirming that part at Pelican is the right one - it's a bunch of places and looks the same in each but I never saw a definitive part number.
