Q1...NO, no sealant.
Q2.... Buy some Vaseline. good to have around...
Q3.... After you install the manifolds, definitely. High marks to you my friend, for undertaking this endeavor.Theres a bit moreto it..(as I'm sure you have discovered), than the basic pull the stuff, clean and re-install....I hope you are doing all the vacuum tubing, and rubber elbows, and intake plenum to runner hoses large and small, in addition the the "O"rings at the MAF you mentioned. Use the Vaseline on the "O"rings...works best in my experience..

1 & 2: Any kind of lube helps a lot with insertion, especially of the injectors. The o-rings seal without any sealant. Check the injectors after insertion to make sure none of the seals got hung up on the manifold lip, something the lube helps to prevent. I use white grease. Whatever. Spit would probably work.

3: Easiest to attach the injectors to the rails with the clips and insert the assembly at a slight angle front to back, making sure each injector is in its hole and work the rail down. The only reason I prefer this is the stop in the manifold is a bit low and allows the injector to drop too far making clipping to the rail harder after insertion. Also, it is possible to not clip them properly and risk a fire. Clipping them to the rail first makes this problem less likely. Also, I remove the rails with injectors. Sometimes one will unclip, but it works for me, at least on my 89.

Super rock on for the help...I have/am going to replace all the vacuum lines in the engine bay, and also am rerouting all the lines that go under the intakes out from under there and over to where the power brake booster is just in case I ever need to get to one. however, I still do have the main vacuum that feeds into the 7-way splitter going under there, that is all. Many thanks from me for all the help. I hope to have pics up after the install tomorrow and with a tad of luck I will be able to crank the shark up Sat. Night.
Please, all say a few prayers for the the Gods of BWAAAAHHHH!

Hey Folks, can you help me out here with a couple of quick questions? I appreciate it.

I am having a tough time getting the fuel rail / injectors out.

I have:
Disconnected the fuel lines to the rail on both sides and they are free.
Removed the plug wire holders from the rail.
Removed the retaining clips from the injectors. (One was missing, any idea where to get a replacement?)
Disconnected the clips holding the wires to the injectors.

I tried pulling up on the rail, but it wont budge.
Did I miss something to disconnect, or am I just not pulling up hard enough?
Is there a tool i need to be using here to leverage up the injectors?

Any help is greatly appreciated.

waaay back from 2006....
get some WD 40 and spray the injector bases and let them sit for an hour.

NOTE before removing the injectors or spraying anything,
get an airgun and blow out all of the sand and other debris so it wont fall into the cylinders.
Cover the intake opening with a piece of plastic

NOTE when reinstalling the injectors use Dow Corning 111 on the O rings this will keep them soft,
and they will easily slide into postion

I just did mine a few months ago, my fuel rails actually came out rather easy, I removed all the clips as you did, lifted one end up a little and then pulled up on the onther end, really no trick to it. If the o-rings are hard and baked, it may be more difficult. As for the injectors, I was very careful and just pry'd them out., When you reinstall, I found it very easy to assemble all of the injectors into the fuel rail first, and securing the clips, and then setting all 4 at once while using equal pressure to the rail above each injector to seat them into the intake.

Thanks All. Your suggestions worked like a charm.

I let a little PB Blaster soak in for a couple of hours, and that really loosened things up. I used a small pry bar for just a touch of leverage under the fuel rail and it all slid out. For injectors that were in the manifold, I took some long 90 degree angled needle noses and gently slid them under the edges of the injectors and used them for a little leverage to pull them up and out.

The only bear became the connector clips. Is there a special trick to these? I used a pair of picks to pull out the wire retaining clips, but there had to be a better way.

Thanks again!

I'm sure there is an expensive tool for that, but I think a pair of picks does the trick, thats what i did, just be careful not to lose any.
