ASSEMBLY AND DISASSEMBLY OF FUEL SYSTEM 

 

Before repair procedure   

Warning：

 

·Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. 

Always keep sparks and flames away from fuel.   

·Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious 

injuries or death and damage. Fuel can also irritate skin and eyes. To prevent 
this, always complete the following  “Fuel Line Safety Procedure”. 

 

Fuel Line Safety Procedure 

Note 

·Fuel in the fuel system is under high pressure also when the engine is not 

running.  

1．Remove the fuel-filler cap and release the pressure in the fuel tank. 

2．Remove the fuel pump relay. 

3．Start the engine. 

4．After the engine stalls, crank the engine several times. 

5．Turn the ignition switch to LOCK position. 

6． 

Install the fuel pump relay.

 

 

After repair procedure   

Warning： 

·Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious 

injuries or death and damage. When installing the fuel hose, observe“Fuel 
Leakage Inspection” described below.  

 

Fuel Leakage Inspection     

Warning：

 

·Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious 

injuries or death and damage. Always carry out the following procedure with the 
engine stopped.   

 

F-14

Caution： 

·Connecting the wrong check connector terminal may possibly cause malfunction. 

Carefully connect the specified terminal only. 

1．Short the check connector terminal F/P body GND using a jumper wire. 

2．Turn the ignition switch to ON position to operate the fuel pump. 

3．Pressurize the system in this way for at least 5minites to be sure of no leakage. 

·

If there is fuel leakage, inspect the fuel hose, hose clamps, and fuel pipe sealing surface, 
and replace as necessary. 

4．After repair, assemble the system and repeat Steps 1 to 3.   

 

Fuel tank removal/installation   

Warning： 

·Repair a fuel tank that has not been properly steam cleaned can be dangerous. 

Explosion or fire may cause death or serious injury. Always properly steam clean 
a fuel tank before repairing it. 

 

·Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious 

injuries or death and damage. Fuel can also irritate skin and eyes. To prevent 
this, do not damage the sealing surface of the fuel pump until when removing or 
installing.
