Re: Fuel Problem/Starvation D2-55 Engine
Is the tank venting ok? Had similar problem years ago and it was the breather blocked and the tank was going into vacuum.
Had another similar issue and it was the return line valve (a simple ball bearing on a seat) in a CAV type filter, it had a spring loading pressure on it moulded into the top of the Filter, this seat got a little bit of crap/rust on it and effectively stopped the release valve from operating this caused the engine to stall out as it flooded.... Check return line from the end of the 'injectors excess fuel line' to the pump IF your engine has similar system...
