There are quick connects on both sides, BUT! The "front" side also have the pressure regulator and a vacuum line connected to it, so I suggest to leave it as is, and just unscrew the filter from the regulator. You will need two pretty large wrenches (don't remember the sizes off the top), or a wrench for the filter and a channel locks to hold the regulator. Also, put a copper crush washer between the filter and a regulator to prevent leaks.

Quick connects do not require any tools, I just used needle -nosed pliers to push it in. Also, on the regulator, there is a valve to release fuel pressure, I suggest you do that before disconnecting any lines. Alternatively, you can pop the fuel pump fuse and start the car and let it run until it dies.

Curious how your leather is holding up after the leatherique treatment and that other stuff you put on? I did leatherique on mine immediately after I bought it and it takes the beating from my *** daily and still looks amazing. Definitely doing it again this summer once it gets hot.

Its holding up just fine, but its no surprise really, I have been using leatherique and been impressed with it for many years. I don't drive the car as much as I probably should, though.
The leather in E39 is the softest napa I have ever seen, and I'm starting to wonder if it was ever processed to the same degree as leather in later cars, since it responds to leatherique so well.
In any case, yes - yearly treatments are recommended to keep it up.

Finally did my PS reservoir and hoses yesterday. I had a slow drip, but over time it has apparently developed into a bigger drip, until one day I lost some of the fluid that made my pump sound like this:



So it was time to address that. Bought replacement kit at FCP:



Fluid was leaking both at the reservoir and at both hoses connections, which suggested just really old hoses and possibly cracked tank itself. Disassembly started:



Hoses were original. Soaked:



Ripped it out:



That’s pretty bad!





New reservoir and hoses are ready:





New o-rings:



And all bolted up to the cooler:



And to the pump:



Flushed and re-filled the system. No more fluid on the floor! Steering is also super quiet with the new fluid.

That's pretty awesome right there...

I did this on several E46's, and it's funny, there was this long time theory where people felt that any power steering leaking down from the reservoir was just from the cap "relieving itself" of pressure through the tiny hole where the ribs are where you grab. I think there was an extremely extremely long thread about that, people claiming it was the reservoir, swapping that out, problem solved, etc. You know what it was all along? Just a bad O-ring in the cap. Like a $0.60 part, HA. So if you ever see it weeping from the top and running down the reservoir, replace the O ring first and you may be good to go for many thousands of miles more, but clearly in your case the hoses were shot! Job looks pretty simple..

Did you clamp everything hose-wise outside of the car so it matched the original layout? Appears like you did that, and was wondering why, rather than connecting the hoses down low, and having the clamps loose so they could still move a bit and then clamping them once everything is all mated up...

Yeah, I tried the gasket trick first (I had an old cap, which wasn't leaking), and it didn't help. Overall, the reservoir and hoses were not that expensive to fix the annoying leak.
I did clamp everything outside, and just dropped the hoses from the top - I did line them up so all bolted down perfectly. There is really a lot of room there to work, but I guess could be done either way.

Yeah, you we right, definitely was the pump whine starving on the fluid and gulping some air.

Wait...no, I was wrong! I thought you had a faulty pump, but it was just your hoses and reservoirs. Much easier fix.
