Either up above the fuel tank, or in the pipes to the front where they go through the plastic covers behind the cills?

Yep most likely to be on the "hidden" pipe run after the pipes exit the ABS modulator and disappear behind the LHF inner wheelarch, then down under the chassis rail to the back, under the tank cover.

If the diaphragm in the servo fails then brake fluid can get drawn back through the servo and either into the engine if petrol or into the vacuum pump if diesel.... If petrol you usually get white smoke out the exhaust.... Outside possibility the fluid is running back inside the car from the servo and getting soaked up by the carpet and soundproofing behind the brake pedal.

Brake master cylinder seals could be leaking thus allowing brake fluid to be drawn back into brake servo. Can do this for ages and fill brake servo with no signs of external leakage. |

if its going into the servo it will be drawn into the inlet system and burnt out through the engine so you may not see it. White/light grey smoke? 2015 Range Rover VSE 4.4 SDV8. 1998 BMW 840 Sport, 2008 Aston Martin DB9

It goes to the Pre-Charge pump used for DSC, HDC and ETC. which is mounted on the inner wing. It sucks fluid from the reservoir and injects it into system prior to the ABS module bypassing the master cylinder and ensuring adequate pressure. |
