Hi friends, You've helped me on several occasions with this back hoe. I again come with a dilemma; the 2 inch by 18 inch low pressure hose connecting the hydraulic tank suddenly seems under pressure. It purges the hydraulic fluid from the flanged fitting to the pick up pump. I had gotten a new hose and upgraded threaded clamps. I could not get it to stop leaking while it runs and it purges when I try to load it by just moving the cylinders. I wonder if it has some problem in the pump causing pressure to 'bleed' into the low pressure side. The hydraulic tank is vented.
