HELP. My Peugeot 806 1999 HDI model had a new pump etc before we bought it. However, 4 weeks after we bought it, it sprung a diesel link at the union on the pipe from the pump to the diesel rail (at the rail end). The Green Flag man tried to tightened it (but I suspect overtightened it) and couldn`t, after many attempts, stop it leaking. I bought a new pipe (=A37) and fitted it, not tightening it too much...3 days went fine with no leaks. However, today, it`s started leaking again...now what? Do I retighten it and can I use threadlock to stop it loosening again? The engine does vibrate but I wouldn`t say it was excessive.....how tight can I go???....TIA.....
