Get a short length of rubber fluid line that is SAE rated for gasoline and four small hose clamps and dubbah clamp each end of the hose to the pump line and the mating plastic fuel line.

The real problem is that the white check valves, though even if new, when pushed in, the interference can cause the internal check valve from operating correctly. I gave up on one pump to get the check valve to operate, the supplier had no suggestions on vetting out the lousy quality control on that.

So, you may be faced with a long cranking cycle after the car sits, and the fuel retreats from the fuel rail back to the tank after shutdown. I thought about rigging up a temp switch to turn on the fuel pump from inside the cabin so as not the wear out the starter or the battery, but just haven't given in to that point yet. I guess after the second battery or starter, I'll wise up.
