FPR hose size

[MistaScott]

Does anyone know the correct hose size for the stock fuel pressure regulator?

?? do you mean the small diameter, vacuum/boost flex line going to the FPR?

the FPR's fuel outlet (returning to gas tank) is rigid steel tube, either 5/16 or 1/4, I'd have re-measure to be certain.

I am chasing a vacuum leak, so I am talking about the rubber line that goes from the steel line to the top of the regulator.
