The engine harness contains wires for the cir-
cuits listed in the table below:
17.
The Fuel Pump for the Caterpillar engine is 
mounted under the console support bracket. It 
is easily accessible by lifting the passenger’s 
seat. See Figure 9.19.
•
A single orange wire provides power to the fuel 
pump. Ground is through the frame via a short 
jumper wire from the pump to the pump mount-
ing bolts.
•
The orange wire provides battery voltage, 
unfused, from the regulator when the key is in 
any position other than STOP. This is the same 
circuit that powers the fuel shut-off solenoid.
•
When the fuel pump is in operation, it makes an 
audible clattering that can be identified with the 
key on /engine off. 
•
A slight vibration or pulsation is noticeable to the 
touch on the pump and fuel line when the pump 
is in operation. 
•
If the fuel system is dry, the pump will be espe-
cially loud until it has drawn a prime.
•
The Kohler engine uses a mechanical fuel 
pump.
