Agree. I'd try that first.

I have a slow leak in the auxiliary hydraulic coupler made by Faster. My M7040 came with one set and have never been used, until now. They came with the spring loaded cover keeps it clean and before I plugged into it I made sure it was clean. Only one couple has a slow drip. I swapped the...
