System Pressure
- Check and note existing pressure. Remove pressure regulating valve from fuel distributor. See Fig 1
.
- Adjust pressure by changing shims in shim stack. Add shims to raise system pressure. Remove shims to lower system pressure.
- A shim change of .020" (.5 mm) will change system pressure approximately 4.2 psi. (.3 kg/cm2
). Ensure any replacement shims are identical in diameter to existing shims.
