Cold Start Valve Fuel Line 1.8 DX engine help

I purchased a set of braided injection lines a while back, mechanic fitted them to the car today but I have an issue with the cold start valve fuel line.
I know the part number for the original VW fuel line is 067133655B and no longer available, I would purchase one if I could.
The Goodridge line that connects to the metering head doesn't do up tight enough it leaks fuel, the old line was rotten and had snapped off on the metal bend, even when the new line is done up fully it still leaks fuel, does anyone know the part number or the official name of the reducer it connects to on the metering head? I have added some images, as you can see when the old connector is fully  tightened there is still thread left but the new line no thread can be seen and it is still not tight enough.
Any help is appreciated, I have been searching all day for part numbers and have drawn a blank.

Thanks In Advance

The line that connects to that fitting on the metering head is not the cold start injector, it should go to the warm up regulator. Not that that answers your question, as you still have the issue with a leak.
I'm sure there must be other folk on here that have had goodridge hoses though.

I believe the mechanic has sorted it now, I got the cold start and  the warm up regulator mixed up when typing it out.  👍
