fuel lift olive and nut size?

went to hook up the fuel pipes to the lift pump and return on the fuel tank (below drivers seat on a G-reg). The olive on the pipe was damaged on the lift pump side, so need to replace the olive and the nut.

Parts diagrams only show the nut and olive for the return pipe. It doesnt show anything for the lift pump. What part number is the lift pump side? Or what size and thread do i need?

The pipe has a diameter of 9mm.

Thanks
