That looks like the base of what used to be a stock two port vacuum port. Now you just have a huge vacuum leak. Remove and put a pipe plug in there. I can get you the BSPT size when I get home if no one chimes in.

That is a broken 'gas filter'. It is a vacuum distribution port.
Since it is broken, it is an active vacuum leak, remove and cap the port or replace with a new filter. Your choice.
Port thread is 1/8" BSPT.
New OEM options if you'd like a convenient vacuum port:
90917-11022 - 1 port
90917-11023 - 2 port
90917-11027 - 3 port
If you want an oem plug:
90345-51006

We bought this FJ with a Holley Carb - all of the emissions stuff was pulled off. Do we even need this? It sounds like we could just plug it.

Need is dependent on what kind of person you are. I personally would buy a single port filter to use as a quick diagnostic tool for a vacuum gauge or if you want to have a permanently mounted vac gauge.
If you don't, then a plug is sufficient. I edited my above post to include a part number for a plug.

You didn't say what year your 40 is, but later models use that vacuum source to run the VCV that evacuates ozone from the distributor cap. Keeps your dizzy from rusting so fast.
