You really only need 3 vacuum lines then. One for the vacuum tree, one for the fuel pressure regulator and one for the PCV line. If you want to use the EGR system, then you'll need one more. That's about as basic as it gets.

Thanks, I'll just plug the others then correct?.
I have my old upper off, it is a gt40 but had a crack from previous owner. I'm getting all my gaskets in tomorrow along with my new map sensor. Also I will be replacing all the vacume lines wile I'm in there.
Where on these motor is the fuel pressure relief? And anything else to lookout for wile I'm at it?
Thanks, as alwase.

Fuel pressure test port connection- behind the alternator... The one in the picture below has a hose connected to it instead of the Schrader valve



What's the hose for?



Fuel pressure test gauge of course!

You really have a mess with those fuel lines! LoL! I hate telling you to spend more money, but either get some stock lines to replace those. Or get the braided kit from Late Model Resto.

Ya, I should. It wasn't my doing but I want her right.
The one steelbraded line goes all the way back, the other goes from the fuel rail (picture above) to a soft line, then to what looks like a factory hard line on the frame rail.
I have another quick question for you. when I took off my upper manifold it had a spacer on it. that spacer blocks a hole in the middle of the upper and lower intake manifold, does it matter that the small center hole is blocked off with the spacer? Or should I ditch the spacer all together? I'll attach a picture of it, thanks guys thanks a million. I should have my new map sensor tomorrow morning, who is to have that going for me..lolol.

Spacer is not really hurting anything. Lots of guys use them. That being said, you can remove it. But.... Your intake bolts may be to long then. Just keep the swap simple and install the intake like you received it.

Ok, keep it simple stupid,lol I like that.
So the small center hole being blocked is no concern?
Also How do I relieve fuel pressure with no valve or whatever, just pull a line?
Sry, I am a new at this... But I love it.

The center hole is part of the EGR system. Being blocked off won't hurt anything. Just don't expect to use the EGR. Pressure should bleed off over time naturally. But you can loosen the clamps on the fuel line to relieve pressure and catch the excess gas in the lines with a rag. But let the car sit for a while beforehand.

Looks like your new intake is threaded for the ACT sensor already.

Ok, I got fuel rail and injectors out today. I don't think there stock mustang injectors, I think Explore injectors. they have four holes on the inside of them I'll attach a picture. I got a new O ring set for all the injectors but I need to know where to get the little plastic hat or whatever there called at the bottom.
I also ordered a new fuel line liljoe07..
