I have an MC Express rear turbo with an italian fuel pressure regulator on my RX-1, anyone know where I can get a new spring and diaphragm? The current diaphragm does not have a hole in it but the spring had rusted and fell apart. It has one port in, two out and one bypass.
If not maybe someone could point me in the direction to replace it with something better. John
