Don't do what I did and screw up the conversion between Newtons and inch-pounds.

If you do use crowfoot wrenches, make sure you look up the torque conversion tables.
Certainly the offset - the table changes the torque settings depending on how far off center you are wrenching.
You should not have removed the fuel lines. The ends opposite the injectors go into the delicate injector pump delivery valves. These delivery valves should not be disturbed or contaminated. The flanges that hold them in the injection pump must be torqued but not over-torqued. When you install the fuel lines you must hold the delivery valve flanges to keep them from turning. Absolutely no debris may enter the fuel delivery system anywhere. Think of this as surgery as opposed to a tire change.
Well, in order to replace the gear case gasket, which is the objective, I had to remove the fuel lines. In any case, it's done now. I will be replacing the fuel lines just because I want to. I have removed the valve spring holder on the first one (I assume that is what you are calling the "delivery valve flange"). I also removed one delivery valve and the holder to inspect as the manual suggests. I think I will just replace it.
In my other post, I described how I needed to get a wrench on each holder to keep it from turning. They are so close together, it appears that I will need to remove the middle holder to get a wrench on the 3rd holder. I was able to get the fuel line removed without holding the last holder, but I suppose that I will need to take care to hold each individually when torqueing the fuel lines back on. That means the holders will have to be re-installed sequentially, right?
