I hope that you posted the wrong image.
That one is needed to join pipes, but it's the wrong one to use when making the ends to go on hoses or into the T-pieces - you need the 4.75 DIN for that.
Ask me how I know this

I’ve used this for both @Pingu, no issues to date, you’ve now got me curious!!!
The former pictured is reversible to make concave and convex flares?

DIN has a different profile to SAE.
The DIN tool can only make the convex flares, the SAE tool can do both (hence why it is suitable to join pipes).
You only need to make concave flares on our cars if you are replacing a section of pipe, as all the pipes terminate with convex flares and male unions.

I have a bit of a brake upgrade I want to put on the rear of the car but first things first I need to replace the disc backing plates (this job is not a nice job)
15 years has taken it toll on these parts but don't want to bolt new parts on to this. Discs and calipers are off but you also need to remove the hub to put the brake protection plate on complete. With the hub removed I have taken the decision to do rear wheel bearings also, seems silly not too at this point.

The stock rears have been really quite good but could not resist having a matching set.
So the rear brakes are finally on car, new ball joints top and bottom, new rear wheel bearings and calipers fitted. Pics attached of the before, during and after, pleased with a the results.

Nice job Brian!

Next part of the plan is to get the car back on the road for the first time in 16-17 months, booked the car in for a wheel alignment after the work on the rear and had a more bespoke setup applied. The car now has 2.5 degree camber up front..
Refurbished the OEM wheels with an anthracite grey finish. Love the new look.
Taxed the car ( had to squint whilst paying as this car is in the highest tax bracket).
Picked the car up from the garage
and almost immediately the dash lit up like Blackpool illuminations. DSC, Engine management, traction control lights.
A scan of the codes showed that the throttle position sensor was showing a fault, but of investigation shows that the S54 has two sensors, one on the rail that opens the throttle butterflies and one on the throttle actuator. Ordered a couple of replacements online and got the fitted.
The lower sensor requires the air box to be removed, easy enough to do, there is a great write up on pelican parts to follow.
The replacement part were aftermarket however the new parts were identical but had the bmw logo ground off.
Car reassembled and codes cleared down, test drive for 40 or so miles and all seem to be fine.

Sounds like the inlet cam sensor I got for my Z3 Brian, original Bosch part with their logo removed (got it through ECP).

Yes it’s crazy, nice to know it’s the correct/original part though.
It’s been a while (almost a year 
) since I posted an update on the Z4M. I’ve had lots of fun in the car last year, drove the car more on the road than I can remember as well as hooning around the track. Really happy with where the car is at apart from…….
Sliding around in the seat.
I have considered putting in a bucket seat for a while but always resisted but the time has come.
a Recaro Pole Position fitted in and if feels superb, I still have the passenger side to do and will do a bit of a write up because the Z4 cabin is a challenge to fit a seat into.
Cannot wait to get out on track and try it
Now for an unsolicited picture of 3 Z4Ms at Anglesey, pft, how common are these cars, btw, the grey car hiding behind the mini is supercharged!!!!

That looks great Brian 
Well this is a well trodden path with a certain custard flavoured Z3
Please do let me know when you done with those seats - with all these tasty Z4M knocking around I’m getting more and more tempted, who knows by the time you retire this one I might be one of those awfully modern Z4 drivers too

I've said similar of late, so much for exclusivity
really giving it some welly, seems like every Saloon on the track had a red Z zipping by them.
