I have a 2H diesel (1982) Runs
well except.
On going up hills the engine just dies. (looses power and then stops)
After a couple of tries to start to start it will go again for another 1-200 metres.
On the flat it seems to be OK even at 100Km/Hr

Peter,
The problem would be the
fuel delivery pump, I am not familiar with that engine, most modern engines have the delivery pump in the injector pump but some old ones had a separate pump which in the new electronic versions is electric.
This pump is the one that brings the
fuel from the
tank to the injector pump.
It has probably lost suction capacity which is why it is OK on level but not OK uphills.
Take it to a diesel injection specialist.
Otherwise youcan check for air leaks from the pump back to the
tank or even a blocked
fuel filter.

Thanks for the assistance.
Armed with your thoughts and a "specialist's" estimate of $500 to $2,000
to remove and identify the problem in the pump, I started a search for
more finite symptoms.
After removing the
fuel input to the pump and supplying
fuel from a can,
the motor worked fine. I then eventually chased the problem to an almost
totally blocked
fuel pickup in the
tank. It seems that the pump was
cavitating when higher volumes were required, and the extra height to
lift the
fuel when going up
hill made all the difference. Unblocked with
a straight length of 1mm spring wire.
Thanks again

Ahh...I had a 2H for years..wonderful motor. On the drivers side of the motor, near the front you will see the injector pump. Just behind this is a white plastic knurlled knob. This is the hand primer. Have a look for leaks around it. Also look for leaks around your
fuel filters.
You may also have a loose
fuel pick-up in your
fuel tank.

Steve,
That
hand pump is where the delivery pump is located...

Steve,
It wasn't there, but you sure helped me isolate it. It was the suction pipe inside the
tank.
Regards,
Peter
