Can someone give me a number of the proper flush face coupler I need to use to get the full benefit of the high flow hydraulics from my s650? The numbers I had been given (FEM 501 and 502 8np) do not seem to allow for full flow. Am I making this more complicated than it is? Also, will a 1/2 hose allow for the max flow? Thanks in advance for any help.

No a 1/2 in hose is not even close. At 30.5 GPM you really need 1 in hose.
The following table was pulled from www.macshydraulic.com
As for the couplers, you also need a 1 inch coupler.
The question to ask Bobcat is whether a 1 inch coupler will join with the couplers on the loader.
My low flow attachments that use hydraulic motors came with 3/4 inch hoses and couplers so did my backhoe attachment.

Thanks for the info.
