Note: Always tighten the fittings with your hand before you use a wrench. Support the hose and the elbow while you tighten in order to avoid the following damage: twisting, kinking and side loading.
Loosen elbow (4) and jam nut (5) .
Hand tighten the nut on the hose (5) to the elbow (4) .
Install the other end of the hose (6) to the pump fitting. Tighten the nut to 125 15 N m (90 11 lb ft).
Hold the elbow (4) in position and torque the jam nut to 145 15 N m (105 11 lb ft).
Support the elbow (4). Tighten the nut (5) on the hose to 125 15 N m (90 11 lb ft).
