Hi there, we have a 2007 120 multijet van that yesterday stopped dead. I discovered a pool of diesel on ground in front of engine and subsequently found a rubber fuel hose (with jubilee clip) had pulled away from a hard plastic fuel tube across the front of the engine. I am the second owner so don't have repair history but this arrangement looks like a patch up? Should this hose have this plastic insert or has this been a "temporary" repair at some stage?
