Please ID this part on intake manifold

[architect]

Hello!

I am swapping carbs pretty soon, can someone IF this part? It’s looks like a sensor with two vacuum hoses coming out.

Bigger question.. do I need it?? (non-smog now) switching from a 32adfa to a 32/36 DFEV.

If not, should I remove and plug up, or just connect the vacuum lines together?

Thanks!

I believe this is an EGR port?
M18 x 1.5 (O2 sensor size).

Can anyone confirm it can be deleted?

I deleted mine. I replaced it with a plug, but it leaked, so I eventually just put the original sensor back in without the tubes.

Ah okay then! Delete it goes...

I am assuming the elctrovalve sensor below the carb can be capped off too? I have a Fireball ignition system...

And it looks like AR sells a better tee for the intake to brake booster line... this will eliminate the “capped” vacuum port shown above, right?

Can someone please confirm the sensor on the underside of the intake manifold? It has two wire terminals and is connected to the main harness.

Is this needed? Can I delete too? I have now switch carbs and delteled all smog components.

I think it’s an intake air temp sensor?

Wow that’s what exactly what I’m looking for! Thank you’

Cool,...shows me exactly what to expect, and I see no surprises. With a DFEV, I'll only use vacuum for the Spider's brake booster. I'll plug everything else flush, if possible. Timing advance will come off of the DFEV. Choke is electric, so +12V from my old ADHA idle cutoff solenoid lead,...
As usual, nice link, PaulC!
Thanks, Todd.
