The Sears Craftsman click-type torque wrench I have has both scales.

Try this rule of thumb -- lbft value is 74% of Nm. If you round to 75%, you can probably do the math in your head.

************************ has the delivery valve socket. Might other places that sell it. Possibly for less. Try Phil.

I found a deep 27mm socket at Home Depot that fits over the injectors.
