1991 thru 1993 Dodge Truck Fuel System?

[JGC403]

Are all the engine options Multiport Fuel Injected for these years? Do these years have a return style fuel system that there is a pressure regulator mounted on the fuel rail; or is it returnless with the regulator mounted on the sending unit in the fuel tank?

Do not think you will find much milt-port till 93. Yes they are regulated but were will depend on the year.
