Fuel Manifold And Lines
(6) Fuel supply line to cylinder head
(7) Fuel manifold The fuel pressure regulating valve keeps the pressure in fuel manifolds (7) between 415 to 450 kPa (60 to 65 psi). Disconnect one of the fuel lines (6). Install a tee between the line and the manifold in order to check the pressure in the fuel manifold. Connect the 1U-5470 Engine Pressure Group to the tee and operate the engine.
