11 Auto Patrol diesel and no fuel.

Hi Lars,
have you bled the air from the injection pumps. There are little bleed screws in behind each pump unit, they have 2 flats on the screw.
Scan below on bleeding the fuel system is from the later grey No11 Operator's Instruction Book.
Early style fuel system is similar but the injection pumps bleed screws are at the front of the pumps.

If you have bled the pumps and are still getting air then it is possible that one of the injector needles has stuck open. This lets compression gases back into the system thus, seemingly filling the system with air.

With the injector line nuts loose at the injectors and the main engine cranking over, watch for a spurt of aerated fuel coming from the line nut as compression pushes past the stuck needle/seat.
Alternatively remove the injectors and test them.
This can be done by removing them and re-attaching to the injection lines and cranking the engine over with the pony with the fuel levers in the on/run position. The injectors should atomise the fuel to a fine spray with the injectors giving off an audible skwark. If you get a stream of fuel from an injector it is most likely the faulty one.

WARNING, face the injectors so you will not come in contact with the spray. The spray can penetrate your skin and give you blood poisoning with possible fatal results.

Hope this helps.
Cheers,
Eddie B.

I managed to get the injector screws loose but it took an impact driver. I also found the bleeder valve on top of the pump drive housing leaking air into the system. What can you say for a 1937 or 38 early model. It runs well and starts good. Anyone looking for a spare 11 out there?
