Canton Accumulator ??

Anyone install one of these? Looking at the 2 Qt one. Which kit as far as hoses, valves and oil filter adapter is required? It's for a 69 Dart with stroked 400 high HP. From what I understand about these things is that oil is under pressure in the accumulator and is forced into the engine past the filter; what makes it go back into the accumulator for the next start up or is it the oil pressure that fills it so meaning you have to get out of the car and close the valve while engine is running? Enlighten me if you all could. Whats your opinion cause I had 1 engine failure/problem quite some time ago and builder blamed it on cold starting. Whether or not he was right I dunno but with the money I invested kinda want a little more insurance on this one. Appreciate all opinions.
I have never used an accumulator. I wonder how many engines are cold started and never had a problem ! I think ur engine builder is full of ---- ! How could believe that ?
