Elk S-550G questions

[SandyHommer]

Just bought this yesterday. I am looking for a serial number and can't locate. I would lie to know the year made.
Also need to run a return hydraulic line to run my log splitter.
will the adaptor listed in aux parts allow me to run a dual line?

YES, I have made my own 3-point splitter and I use the adapter for that purpose.
Note that when not used you need to have a short hose to connect the 2 adaptor ports as the adapter need to be 'open circuit'.
While with my 4" log splitter cylinder (surplus find) speed is not great but power is abundant.
While not speedy, it still gives you a good work out.
