After discovering a fuel filter/separator full of some organic crap, I decided to clean out and change all filters on my Volvo MD5. After the usual hassle of venting the system to get the air out, I managed to finally get the engine to run normally for 15mins to half an hour, before it starts to hesitate and eventually stops. Reventing the fuel system enables the engine to be started again, but again, just for a liimited period.
I've gone through this cycle a lot over a few days, and am getting a bit frustrated, by now, and had to cancel my partipation in a classic yacht regatta this weekend.
One possible cause that crossed my mind was the fact that ambient temperature was quite high - but as far as I know, diesel engines don't suffer from vapor lock, do they?
Anybody any suggestions what may be causing this loss of fuel system integrity?
