I connetced the 3/8" tubing adapter to my 1 1/2" PVC line and no matter how much I tightened the hose clamp, there's a leak between the black washer and the PVC pipe. The pump's suction line was easier to connect - I simply connected to the pump's drain plug outlet on the suction side.
Any ideas how to stop the leak?
