Is is workable to use the chain oiler as a smoke fluid pump?

My thought is to use a loop of tubing so that smoke oil is always circulating back to the tank. The valve to the muffler comes in the middle of the loop. A restriction on the return at the tank side of the tee would provide pressure to squirt the oil into the muffler when the valve was opened wih the servo. .

The ECHOs I mess with have a nice looking oiler that I have been removing. This seems like a simple neat way to make a smoke system.
