Does anyone have any pictures on how to install a fuel pressure regulator on a 5th gen.I bought an adapter from fleabay but it doesnt fit the input side of the fuel rail.And from what i read it is supposed to go on the return side.Well any help would be appreciated.

 

You need to buy the universal Nismo one, it fits properly on our fuel rails. Yes its supposed to be on the return side of the fuel rail.
