Sorry for a late response...
But to offer some conclusion I had an order of parts going already with DMC Texas so I just added a new one. Only another $30 so I figured play it safe... Thank you everyone for the input!

Thought this was interesting

interesting to note that the conductivity of gasoline is reduced when it is an ethanol blend, which may limit the need for the anti-static wire in certain ambient/humidity conditions. I would certainly keep it in, though.

Yes when it comes to gasoline and electricity I would rather play it safe.
My tube also had green pitting on it, plus the fact it snapped in half, so I figured $30 is worth the peace of mind

Any chance someone has a picture of this thing installed?

I have a feeling this might be another entry for my "some parts not included" list that came with my car when I got it.

Hey Jonathan,

Sorry, I got no pic of my installation... I shoulda woulda coulda.. But I have this for any one who needs a quick tutorial... I just cooked this up for anyone doing this job on their DeLorean. Here you go;

Here's a pic of my existing (shortened) tube in the tank, if that helps any....

I don't understand why it wouldn't dissipate with fuel constantly circulating through the FD (grounded to the block) anyway, or the tank to frame for that matter.

And why the heck is it hollow???

Is there any chance this "vent tube" isn't for static electricity build-up but it's actually for venting the tank to prevent it from collapsing in on itself?

Whether it would happen from temperature changes of the fuel or more fuel coming out than air replacing it, if the tank pulled a slight vacuum, it would collapse in on itself.

I've seen this happen with plastic or fiberglass tanks out on process equipment in industry where if you suck what's in it out quicker than you replace it with either more fluid or air, it will destroy the tank. Those tanks can handle a fair bit of outward overpressurization before they burst, but very little inward pressure from a vacuum getting pulled.

I look at the images on the parts diagram and nothing there says anything about it being a static wire. Just curious is all?

Unless I'm missing something here, isn't the anti-static line in fact mounted in the vent tube's port (which connects to the filler tube and eventually terminates in the evaporative control system), thus it kinda has to be hollow in order to vent the tank, unless I'm missing something, right?

While the vent is absolutely necessary, the wire/tube itself running the length of the tank really isn't. After all, the 5 gallon or smaller plastic gas containers that you buy from the store are essentially the same as our fuel tanks, and yet, there's no anti-static wire in them, right? Why a concern over static electricity with 12 gallons of fuel, but not with 5 gallons? Probably because the chances of a problem occurring are in fact astronomically low.

You can clump this together with the air deflectors/TAB shields in the 'what's the exact purpose/function' folder of DMCL decision making mysteries
