I was under the assumption that the vacuum tree under that intake could be used without having to drill and tap for the original vacuum tree. Is there anything else that needs to be done other than tapping and drilling for the act and egr?
Perfect photo to show the difference between the HO vac lines and the early EGR explorer
On the HO intake, the two capped lines are for the charcoal canister (front) and MAP sensor for early SD cars (rear)
I made the PCV setup match the mustang by removing the front fitting on the underside of the plenum and drill/tap for a plug here (you can see the plug on the HO intake).
I also removed the large brake booster plug and am drill/tap to install the mustang vacuum tree block. This will give the EGR and FPR it's own vac port to hook to.
I plan on pulling the long skinny port out from the rear and put a small port in (need to find one)
I also plan to pull the long bent port out from the front and put a small port for the charcoal canister.
The later intakes even have coolant routed to the manifold. Those ports can just be blocked off. This is a later, EGR intake that actually has coolant ports around the PCV valve. These are not vac ports
And a later non-EGR intake with integrated coolant (the lines marked 7/32 cap)
Here's how the cobra setup is factory plumbed for reference. There's a small line for the charcoal canister on the front. No provision for a MAP sensor.
