It is a tricky job but not actually hard. I can fit one in about half an hour.
Just going from memory...
You need to remove the upper suspension arm. So the top ball joint is the first thing.
You undo the nuts on both ends of the pivot shaft on the inner end of the top arm. To get to the nuts I work from in the wheel arch, other people might remove the radiator. You will probably need to bend the inner guard panel to get to the front nut, I do this with a pry bar and stick a block of wood to hold the panel out enough to get the hands in without creasing the panel.
Undo the small bolts that hold the retainer on the pivot shaft and then slide the shaft out and remove the upper arm.
Remove the little rebound bump rubber.
Two screws hold the displacer retainer.
Undo the hydro hose from the pipe.
Give the displacer a bit of a turn to unhook it from the subframe, I use an oil filter tool to get a grip.
Then the displacer should come out, they sometimes need a bit of a pry to get them to drop out.

If the barb on the bag has really had it, you can cut it off, drill and tap the remains to 1/8" BSP (BS Pipe) or NPT pipe thread. Drill as shallow as possible, put grease on the flutes to stop swarf getting into the bag.
Then screw in a 1/8 x 3/8 pipe nipple, and have a new hose made up. Re-use the top hose end if like me you can't find new ones (they are 5/8-18 thread).
I used Pirtek MPH 06? hose, it is textile braided hydraulic return hose. Nice and flexible. Rated @ 500psi.
[edit] typo, thread I used is 1/8 BSP, not BSF!!

It is very likely the flexible hose where the crimp on fittings attach it to the bag or the threaded end, as others have chimed in with already. The link provided is a wealth of information and I've chosen to use Method #3 in the link here:
//members.tripod.com/austin_america/id63.html
I first tried to have my local Parker Hose crimp on a new line directly to the hydro bag nipple. That did NOT work well for me. I ended up doing the #3 solution with the compression fitting
and then had some high pressure lines made up with heavier crimping, again like is showed in the link:
and I have not had any issues since.
Sometimes, the metal line corrodes and chafes on the bodywork and you get a pinhole in the metal line. I've been able to use compression fittings to splice in just the piece of line that is needed to remove the bad section of metal line.
Or you can go with the easier-to-replace plastic line sold by our host:

It is most likely the hose where it joins the displacer.
Though the last one I repaired was a mouse had chewed through the hose where it goes through the body.

I woke up today to find the left front all the way down and a significant pool of hydro fluid under the car??? Not sure where to start the diagnostic process...Does any one have a nice outline for the detailed steps to remove and inspect the left front Hydro Bag to determine the source of the leak...Any special tools required, potential pitfalls, etc...Also, any thoughts on repairing the bag and or sourcing an excellent quality replacement? Thanks a bunch for any and all help!!
