Hello.

Im fitting EFI now to my ERST and have a question about the fuel pressure reguletor.

Do you think I can turn the reguletor up side down and bolt it to the fuelrail? There is no space for the vacuum outlet on top of the reguletor but if I turn it up side down it fitts very well.

The question is if the reguletor will work properly?
