The vertical rod appears to be connected in this photo.....

Be careful here before making any changes, disconnect that vertical rod at the bottom and if the gap is still there then yes, you have a problem, it *might* be as simple as the shut off valve is incorrectly connected inside the injection pump .

To re connect that vertical linkage rod, use a long flat screwdriver and gently apply pressure whilst moving the pivot .

Remember to clean _all_ the rust and crud out of the pivot cup and lubricate it before re assembly .
