1" manifold ( socket welded is preferred) test pressure range : 450-3000 psi: from test pump hose: union-1st block valve-check valve flow--> - first tee down-drain valve for depressurization and drain-second tee up-block valve--lock open for relief valve-relief valve-back to header----third tee up block valve-reducer-pressure gauge--back to header- second block valve-union-adapter to test piece.
under hood, on fuel rail which is connected to each fuel injector there should be a valve that looks like a tire valve. That is the shrader valve, test fuel pressure there.
youcannot test glow plugs thru the coneector on valve cover you need to actually test the glow plug
You can tell a bad valve by doing a compression test.
Raise the pressure in the boiler until the valve relieves and note the pressure at which it does so.
Do a compression test.
You cannot manually test the EGR valve like you can with most ie. applying vaccum and depressing the diaphram. The EGR valve is controlled by the ECM you must have an OBD-2 compliant scan tool to montinor EGR functions.
