NHRA Fuel Cells rules

it should be AN style fittings. most of the fuel cells have 8AN size fittings in them. just order a female 8AN and some 8AN fuel line. install the female end on one end of the hose and screw it onto the fitting in the cell that has the check ball in it. you can leave the other end of the hose open and just run it out of the bottom of the trunk. I have mine double check balled. I have the one on the cell, and a bulk head style fitting with a check ball that connects to the trunk floor. the hose screws onto both of them.
