    You do not cap the return oil line. You have to use a special threaded plug that goes into the pump body.

    If the fuel pump was set up for a 2-pipe system originally, a bypass plug was installed in the pump. It must be removed for 1-pipe systems. I hope the pump hasn't been ruined at this point.
