  1. Update on this problem. Figured it had to be on the low pressure side as any splits between lift pump and injectors would have diesel spewing everywhere. Just to discount a crack in the fuel filter housing, while running at idle I briefly undid the banjo input to fuel filter, this was definitely bringing in a lot of air as it was bubbling and spluttering.. So traced the fuel pipes back to the tank but again nothing obvious. With engine at idle, checked again, bingo! Fuel pipe at tank gently bubbling and on closer inspection the casing is split on the bend, just enough to let air in
  2. Thanks for the pointers. Exhaust is blowing clear, there's only one box, the rest is straight pipe so no issue there. Filler cap off and air intake opened, still dying on acceleration. It doesn't die immediately but chugs heavily before stalling so pretty sure it just not getting enough fuel through. Could there be a situation where its sucking air into the fuel pipes but somehow not leaking fuel out? Using my logical head, that would more likely be happening prior to the lift pump because post pump the fuel would be under more pressure and a leak would occur. HH
  3. Hi, I'm having a problem with my 1998 300tdi. Slow to start, sits fine at idle, dies on acceleration. Sounds familiar, simple fix, change the lift pump. But no! Lift pump changed, no difference. So changed fuel filter, air filter, oil filter (not related but I was in a filter mood). Engine starts slowly runs on idles, dies on acceleration. Possible dodgy replacement lift pump? Off it comes and another one put on. Tested both for blow/suck on activating the pump lever. All good. Start it up, fine on idle, (you know where this is going) dies on acceleration. So I crack
