○Install the double spring clamp in the position as shown, and securely pull up the clamp stopper with pliers. Check the fuel system for leaks after hose installation.

Fuel Hose [B]

Double Spring Clamp [A] Fuel Pipe [C]

CAUTION

Do not reuse the double spring clamps on the fuel line. Reusing will cause fuel leakage.

Replace the double spring clamps with new ones.

○Replace the fuel hose if it has been sharply bent or kinked.

○The high pressure inside the fuel line can cause fuel to leak [A] or the hose to burst. Bend and twist the fuel hose while examining it.

○Replace the hose if any cracks [B] or bulges [C] are no- ticed.

○When checking the DFI parts, do not run the engine for 15 seconds or more without auxiliary cooling (see General Information chapter).

CAUTION

If running the engine without the auxiliary cooling for 15 seconds or more (even at idle speed), the rub- ber component relative to the Exhaust System may be damaged.

○Execute the auxiliary cooling securely in case that fre- quent engine running is required.

•When checking the DFI parts, use a digital meter which can be read two decimal place voltage or resistance.

○The DFI part connectors have seals, including the ECU. When measuring the input or output voltage with the connector joined, use the needle adapter set. Insert the needle adapter inside the seal until the needle adapter reaches the terminal.
