Pump Pressure Test
- With pressure gauge installed, start engine and let it idle. Close gauge valve (for no longer than 5 seconds), and check pressure. Pressure should be 2103-2248 psi (148-158 kg/cm2 ).
- If pressure differs, check limiting valve by inspecting bores in valve and piston for obstructions. Check that piston moves freely in housing. Install new valve if needed.
