Rex B. Yes the tubes are how you tell if it is ported. They are the same no matter how many hydro circuits are on the tractor. You can add another valve to the older style cubs, 782 etc and the Cyclops cubs. I have second valve for the front outlets on my heavily modded 1541. Most Cubs had ported hydro pumps in the 80s and 90s.
