Just talked to Landis. The release valve is located in the valvebody. John you are right, the adjustment is that large hex nut on the left rear of the body. The filter is inside the tank attached to the 3/4 inch line that feeds the pump. That was the good news. When I started adding fluid, the pump started leaking like crazy around the shaft. Landis says that the pump is no good. There is no rebuild kits for it and of course he has new pumps for $450. Has anybody had any luck putting a different pump on an OC3 or OC4?

I do not want to make the mistake of running the pump dry!
