b3 1.6td no.2 injector pipe breaking

[83mars]

hi all, got an issue with the b3 at the moment,
a week or two ago i noticed the cart was down on power so i pulled over and spotted that no.2 injector pipe had split completley just next to the injector.
i got lucky and able to source one that evening, being in a rush i left the main clamp off,
but last night this one cracked off in the same place, it was only cracked last night but after taking it to work this morning it had split off again.
im after sourcing two sets for myself tonite and id like to only have to fit one set,
so any advice or information would be much appreciated.
cheers.
