new here, but here goes:

technically this is a 350sdl, but the rodbender engine went kaput on the previous owner, and it was replaced with the 3 litre 300 engine before i bought it. be that as it may, about six months ago the #1 injector line broke at the pump. so i figured i'd be smart, and replace the whole set of lines and be ahead of the game. the new #6 line was routed differently than the old one, and i'm on the fourth one that has broken. it will shear off under the nut, sometimes at the pump end, sometimes at the injector end. the mechanic noticed that a couple of the loom/brace clips for the injector lines were missing. these were replaced, and in spite of that the #6 line has broken (at the pump end) yet again. what am i missing here? i've owned several mitsubishi, toyota and mecedes diesel units and never have i had an injector line break, until now.
