my car sometimes stops whilr driving along normally and would ot restart.few hours later or next morning car starts normally.had a good look at the engine and disconnected and reconnected all the diesel lines.i suspect there was a leak in the fuel feed line,which works by sucking fuel from tank(there is no pump in the tank) and removing and refitting the lines fixed the problem.is there a kit to change the orings in the quick release fuel line connectors?thanks
