    The replacement unit will fit. The outlet fittings should be the same, the only real difference is injected quantity is slightly less, turning it up a bit less than a 1/4 turn will correct this. It should also slightly advance timing as it increases stroke which places start of injection...

    You can't adjust timing, it takes special tools. You could turn the fuel up, with the pump removed, there is a Pentagon shaped cover on the left side, two screws hold it. Remove this cover and turn the hub until the screw access hole is seen. Insert a 3/32" hex head driver..make sure it fits...

    Fuel should flow through the injection pump's bleed orifice to the case, there is a vibrating wire through this orifice to regulate the flow. Remove the pink wire to prevent flow through the delivery system.

    The Roosa Master pump was licensed to the UK under the CAV name so that part may be available closer.

    Does the inside look like that? If not, go on. You still have the regulator after the pump. A regulator is also a check valve which shuts off flow when inlet pressure is less than outlet. I'm not trying to be an optimist here..

    Hopefully the screen and transfer pump kept the nasty things out of the rotor. That is the heart of the injection pump. Transfer pressure can be adjusted using exhaust gas temperature and desired power but remember transfer pressure also advances timing, delay in timing will raise exhaust gas...

    How dry? If there is fuel inside the housing, it should be good. The next things after the screen would be the transfer pump. This isn't too difficult to service and there is no calibration to fuss with. After this is the pressure regulator and this would require speed based calibration...

    High altitude fuel setting is less fuel. In a diesel, it is always running lean of peak exhaust gas temperature. In this engine specifically, far lean. High altitude means less air density so corresponding less fuel. With regards to your prior fuel system clog, that sounds like badly...

    Sounds like the fuel metering valve is stuck shut. It must move freely as it opens under very light spring force and is closed by the centrifugal force of the governor fly weights. The shut off solenoid also closes this valve to shut off the engine so they like to stick in the closed...
