Slow fuel leak from top of the engine. Filled the valley in between the heads with fuel. Replaced the mechanical pump that sits in the valley behind the fuel bowl along with hoses that go to it. Fixed problem. Did the job myself and boy was it a pain. You have to pull the Turbo off which is not too easy since you have to have universal jointed sockets and really long extensions to get it off. They would probably charge an arm to do this at a shop.
