Theoretically, should fuel be able to come out of the fuel accumulator return line? If it does, it is a sign of a ruptured part?

At this time, I have the return line disconnected at the fuel accumulator and the main line blocked off. I put a clear hose on the fuel accumulator output to monitor any fuel coming out. Of course the car is starting good and idling perfect during the tests, but when I turn the engine off, there is some fuel coming out into the clear hose. It's not a lot, but I'm just wondering if this is something that should occur.

Thanks,
