Cylinders operate very efficiently, so generate almost no heat, you'll get a bit from the pump. 2 or 3 gallons should be lots. If you were using motors and flow control valves, then you'd need some capacity or better a cooler. The auxiliary hydraulics on my tractor have about a 5 gallon tank with a 5 gallon a minute pump. The wood splitter and the backhoe hardly warm the lines, the two hydraulic motors and flow control on the chipper feeder heat the oil up right quick, gets any water boiled off.
Free advice is worth exactly what you payed for it.
