Allen bolts: 26 ft lb
Check valves: 11 ft lb (two small allens at the front)
Pressure relief valve: 22 ft lb
X-caps: 36 ft lb (good luck!)

That 5mm allen in the 'boss' is the pressure relief valve for the power
steering side of the pump. "There may be partial failure of power

...along with frappe'd Pentosin in the case of my spare pump.
The pressure relief valve should unscrew from the 'boss'.
