<When using the fuel pressure gauge set (special tool)>
(1) Install the special tool (for measuring the fuel pressure)
between the high-pressure fuel hose and the delivery
pipe.
(2) Install the fuel pressure gauge set (special tool) on

putting the gasket between them.
(3) Connect the lead wire of the fuel pressure gauge set
(special tool) to the power supply (cigarette lighter
socket) and to the MUT-II.
<When using the fuel pressure gauge>
(1) Install the fuel pressure gauge on the special tool
(for measuring the fuel pressure) putting a suitable
