Ferrules are needed. That injector loom is a fire waiting to happen. You really must get a new loom and do the rail and flexibles from rail to injector properly. Doing the dizzy and the HT leads and new plugs at the same time when everything is off. Two days work in total once you have the bits. The injector loom is available but very dear, so making one is quite doable but takes quite a bit of time.
I do not think you should risk starting the car until this is done.

yes, yes, yes, the ferrules are needed. They actually help the hose form a tighter seal on the barbed piping ends.
I just replaced my plug wires with Magnecor ELECTROSPORT 8mm wires. At first I had a "tic tic tic or tapping noise at the engine. My first thought was a valve. Further inspection with the motor running and the lights off in the garage showed that I had two issues. First, one plug wire not fully seated so it was arcing to earth. That took care of the tic tic tic. Second was there were numerous "dancing blue gremlins" on the wires. I had replacement OEM 7mm wires on the car. I decided that jaguar + fuel hoses + excessive electricity was not a good equation. New wires took care of blue gremlins. I feel MUCH better knowing that the likelihood of an engine fire has been significantly reduced. No sense tempting fate on with a 30 year old car.

You could, but do yourself a favor and just make up a new harness. It isn't hard. Takes a few hours; enjoyable project
Get new ones. Google "Bosch Fuel Injector Connector". Lots of choices and price ranges
Make sure you keep track of the orientation of the hold-down plates. Make a sketch before disassembly. It wouldn't be fun to finish the job and *then* realize it all has to come apart again because the hold-downs are not oriented properly. Not that I would know...ahem.... from personal experience, of course. Just....cough cough...speculation on my part

I figure I could even do what others have done and gotten plugs out of the junkyard off of a couple bmws(they fit I guess?).

When you first look at the engine it seems daunting but getting the rail off was easy I just took it injectors and all. Taped it all off and am going to replace all hoses and ferrules etc and paint the rail.

Each of the 12 holes left open when the injection tubes are removed must be plugged of. Lots of different ways of doing this; I think there's a thread with pics showing some of the different ideas.
I tapped the holes and used screw-in plugs. Very easy.

Oh, yeah, errant spark and fuel under a lot of pressure. Imperative to keep each within it's own confines. Because of my former profession, I am very "fire" sensitive. Mere damage to property, I can live with. The horrible effects on live critters will forever haunt me.
Odd. Is my eye sight going away? Is my ability to count going astray? I count 5 injectors on each leg of that rail. OK for a Ford 10 Viton, but a Jag V12?
In our Jeep fuel pump travails, I came across "easy open" fuel line couplings. Yeah, once knowing how, easy, o'wise a puzzle.
Slick. fast for assembly line work. No threads to strip. Neat look, great seal.

I am going to take the air injection system off my '87 later this summer. I don't think I am saving the environment given how little I actually drive the car and I think it will clean up the looks under the hood a bit.
I'll be replacing the rest of my fuel line hoses at that time too. I just replaced my spark plug wires with Magnecor ELECTROSPORT 8mm wires. $145 and well worth it IMO. An engine fire is the one thing that causes me anxiety with this car.

The reason I went with Magnecor 8mm wires is that I checked the car out with it running in a dark garage. I noticed a significant amount of "blue dancing gremlins" in the V. The OEM 7mm wires and boots may not provide enough insulation for the high voltage required to operate the V-12. I wanted to do everything possible to guard against an engine fire with a 30 year old car that is known to have issues with them. Engine fires and overheating/dropped valves are the two most common things that doom these cars. Both are mainly due to improper maintenance.

Quickly stopped by the jag today and took the last 2 injectors out and the plug wires etc. looks as though atleast one injector was replaced...this shouldn't effect things should it? Looks like a different nozzle.
also, do I have to take off the air pump to get the dang wiring harness out from under it?! Ha jeez the right side doesn't want to come out from under it. Can't wait to clean it all up, a Jag V12 is a mouse castle

- the system is probably not working
- if it is it only pumps air for 45 seconds which makes naff-all difference to the environment.
