Vicar, just checked my service records and notes

Last time I changed one on a Roadster, I found the black rubber feed pipe had perished & in trying to remove that the slim outlet from the plastic header bottle snapped off swear

Nil desperandum, if that happens, don't pay MMC prices !

Car Builder Solutions parts...
Lockheed plastic reservoir (identical to OE) ref FLRES7 approx £10
Brake fluid resistant hose ref BFHOSE £7

Good luck & let us know how you get on
