w124 tdt fuel lines butterlike

[europower]

The w124 diesel metal fuel lines are really a downgrae compared to w123,you never have to worry or change them,built tough i miss them,tha fact is i totally love the way the 87 diesel drives and stops,but im sooper bummed with the construction of the lines and the anti vibration pieces,yesterday i replaced no4 and reinstalled all new anti vibration hardware ,i really thought things would be cool for a long time,so i hoped,then today after a 300 mile drive i came home to find another line had busted,this time it was no5's turn to act like butter,anybody else having this problem? any tips? is there maybe a recall on these because i looka the original lines and they are tougher looking and sturdier than these new MB ones.

Other memberswith 6 cylinder engines have reported broken IP lines.
Thicker and shorter IP hard lines are less likely to leak on any vehicle. Long IP hard lines thinner or not are subject to a lot more vibration and therefore stress than the shorter ones.
There are pressure waves that go through the IP hard lines both during injection and after injection has ended and these waves are strong enough that they can over time actually eat a hole through metal (cavitation). Sometimes even parts of the IP itself get damaged. The engineers try to design things so that this dose not happen but sometime this just dose not work out so well.
If you want thicker IP hard lines many larger fuel injection shops can make them up for
you. But, the cost might be higher than the factory hard lines and you would most likely have to bend them yourself. I had a hard line made for my Volvo diesel back in 1993 and it cost $20 for one. I was about 2.5 feet long. The longer it is the more it cost.
