Fuel cell to pump issue

[myounts40]

Trying to fab up a separate fuel pump/regulator/fuel cell for my nitrous kit. I am looking at an RCI cell with -8AN outlet. The fuel pump I am looking at inlet is 5/16 (Summit's knock off of MSD). I cannot find an adapter that has a -8an fitting that converts to a 5/16 hose barb. All I can find is -8AN to -8AN. This also has to be a female -8AN. here is a link to the cell and pump. Basically I just need whatever will join these two together, even if I have to use a reducer, say from a 1/2 in line to a 5/16, I can live with that.
