Hi Walt and Judy
Thanks for the input as it helps considerably.
I have an electric pump near the diesel tank in the locker which I installed as I fond it difficult to prime the fuel lines only using the lift pump on the Yanmar 2GM. Once primed I can start the engine without the electric fuel pump and run it at about half revs before the engine starts to hunt. The exhaust at this point is clear of smoke. If I then switch on the electric fuel pump the engine runs fin but generates white smoke from the exhaust and the seal on the fuel filter leaks. I guess that the fuel pump is generating too much pressure. What is the make and model of the pump you have fitted and any idea where I can purchase in the UK? Do you have any running issues with the engine when you are using the electric pump?
Regards
David

A slow air leak into the system could also cause the engine to stop. Lyric has an electronic pump in line in addition to the engine pump. We started having problems and I suspected that the diaphragm may have developed a leak. We changed the pump and stopped the problem. It might be worthwhile to check for loose fittings between the injectors and the tank. Maybe a bad gasket on the fuel filter? Good luck! Walt

Maybe a vent issue with the fuel tank?
