A bad accumulator cannot be definatively tested in this way. I had a car with the classic hot start symptoms. I removed the return hose, did not see ANY fuel come out and assumed the accumulator was OK. After chasing the problem around I replaced the accumulator and corrected the problem. I cut the old one open to make a definative analysis and discovered the return port to be completly blocked by bits of the diaphram. I guess you could poke something into the port to make sure it is clear before testing in this manner, it may make a difference. The port has a small orifice inside to limit the return flow so the pump can get up enough pressure to get the motor to run.
