hi
i have an 89 e34 525i. i have recently bought a used fuel pump from a 92 model, on my old fuel pump there is a pressure regulator fitted on top of the pump & on the 92 pump there is no regulator. is it not required for the 92 pump? or is it inline or on the engine, if so where is it located? does anyone know if the 92 pump is even compatable? thanks in advance for any help you can offer. tabby
