Pump is set correctly as per your picture. It has the connecting sleeve right?

Engine should be set to 12 degrees Before TDC on the compression stroke of no1 cylinder.

Insert injection pump into engine and turn the pump as far as the pressure point (until it gets slightly harder) Then insert and tighten.

Remove the connection fitting on fuel return line and fill with 200ml of clean diesel, then reattach.

Undo cylinder number 1 fuel line and crank until fuel comes out, then tighten and start.
