BMW Repair: 1988 BMW 735i, 1988 bmw 735i, fuel hoses

Question
How do i loosen a seized fuel rail?wiring rail has been removed and all bolts and fuel hoses have been removed but the fuel rail will not come off.These are all original parts.Can't afford to replace all injectors and fuel rail,only one bad injector.

Answer
Well it sounds like a challenge,you could disconnect each injector from the rail and pull the rail from the injector rather than removing the complete assembly.Silicone spray might help lube the seals,which I'm sure need replacement.Being patient is the best tool,also sometimes a stern tug.
