There is a reason that fuel injection uses the locking type lines.
A fuel line with a screw type clamp will loose up over time due to plastic deformation of the fuel line. You can go back in and tighten them up and they will gradually loosen up again.
This is not too big of a concern with carbs since the fuel is generally at a very low pressure and will not cause the hose to release from the fitting. But FI is a whole other beast.
It is likely your mod is at fault and not the mechanic.
