don't forget to release the pressure w/ a rag over the schrader valve. The rails and injectors can be hard to get out/off...takes some tugging some times. When you put your new ones in, be sure and lube the o-rings w/ vaseline or something to make it easier to slide them in...if they're new, I don't know if you have to do that, but prob. wouldn't hurt.
Are you buying bigger injectors? I'm sure you know if you change injector size, you also have to recalibrate your MAF or buy a new one.
I'm replacing the intake manifold with the BBK one. I'm going to reuse the same injectors with it, but need to take them out and put them in the rails on the manifold.
IMO the bbk is a waste of money, and you can spend your cash better in other places... For that price, you could get gears, have them installed, and still have cash to fix up your car...
Definetly look at gears before you do much to the engine. The $300-$400 spent on gears & professional install will do more for you car than anything else but NO2 or forced induction.I did a 87-T-Bird Turbo Coupe rear end swap & got the whole rear end with 3.55's & disk brakes for less than $300. Look for an auto trans Turbo Coupe & you get 3.73 gears.
Having said that, here's some help for your current questions...
Look in the A/C repair section for the fuel line tools. They look like little plastic top hats. You will need the 1/2" & 5/8" ones. The hat shaped section goes on facing the large part of the coupling. Then you press hard on the brim until it forces the sleeve into the coupling and releases the spring. You may need someone to pull on the line while you press on the coupling. Put some motor oil on the O rings when you put the line back together.
Fuel injector seal kits with 2 O rings and a pintle cap (Borg-Warner P/N 274081) are available at Pep Boys auto parts. Cost is about $2.74 per kit. The pintle caps fit either injectors with a pin sticking out the injector end or 4 with more tiny holes in the injector end. The following are listed at the Borg-Warner site ( http://www.borg-warner.com ) as being resellers of Borg-Warner parts:
