2H injector line fitting to IP, how to remove?

i got the dvh most the way out but didtnt clear the bore totaly of thread - so the spring under the didnt fire up at me.... reading the manual there is nothing above the spring and the rail shud be holding the lower assembly in place, i doubt it floats.

The "element" is the little piston that, when lifted by the camshaft, pumps the fuel to the injector.
The tappet sits on the camshaft and the tappet raises the element inside the sleeve as the camshaft turns.
Each time the element is raised as the camshaft rotates, it injects a charge of fuel.
The rack is connected to the pinion (22155), and when the rack position is altered by altering the accelerator position, the element is turned inside the sleeve, which alters the amount of fuel injected.

The clearance between the element and sleeve is about 1 micron or less (.00005") - it is critical that you DO NOT get any dirt of any kind into the element assembly or you will destroy the element, because the tolerances are so close, and the injection pressure level is high.

Cheers, Ron.

many thanks Ron, seeing that assembly of small is scary exciting, so complex. Did you read the assembly instruction for this part, bits o' wire (sst's) required to sort the cylinder... many thanks agiain
