Sounds like you have the right idea. Do not send the accusump oil through the cooler as it will take too long to refill the system incase of a pressure loss. Some people use a one way valve, some don't. The oil pump will act as a one way valve I'm told. But what about an oil pump with more air than oil? Use a one way valve just in case. I've used accusump's since they were introduced in the 60's with never a single problem to date. I place mine in the floor board where the pass seat once was. Make sure you place it pointing in the right direction, so when you slam the brakes on, the oil will not run away from the outlet. Just my two cents worth.
