We're hosed

Hoses and brake lines are a challenge on this Frankenstein project.

Brake lines a combination of metric DIN bubble flares and ISO imperial double flares, with a super odd metric double flare on the Tesla master cylinder. Plus, the original ATW front calipers have two redundant circuits so the original master had 5 ports. The Tesla iBooster only has two. And the original rear-mounted proportioning valve isn't practical with this new setup.

Brake and power steering lines complete (less hose clamps)

With barely any room between the battery box and inner fender aprons, and the need to add a Y fitting to split each front brake circuit into the dual caliper configuration, I was forced to relocate the holes in the fender aprons higher to allow enough room.

Old (and one accidental new) holes filled and line run in higher to allow for branching

Power steering presents similar problems with limited room and OEM banjo fittings on the original hoses to the ZF steering box that need to be adapted to the modern electric Mini Cooper pump.

Modified high pressure banjo fitting to AN-6

A nod to originality by using the stock reservoir for power steering

A very tight fit to get power steering hoses onto original ZF steering box

Mini Cooper electric P/S pump with hoses now. Still need to wire it up.

A/C hoses are also a challenge with limited room and all new components (Tesla electric compressor, new dryer and condenser, all with modern o-ring fittings for R-134a but (maybe) the original R-12 flare fitting equipped evaporator and expansion valve.
