Injection Pump Types
There are two different types of fuel injection pump
that can be installed. The Bosch fuel injection pump
and the Delphi fuel injection pump.
Illustration 49 g03721128
Typical example of the Bosch fuel injection pump.
Illustration 50 g03721129
Typical example of the Delphi fuel injection pump.
Both fuel injection pumps are self venting.
Priming the Bosch Fuel Injection Pump
1. Turn the keyswitch to the ON position and allow 90
seconds for the electric priming pump to prime the
system.
2. Turn the keyswitch to the OFF position and then
start the engine. Check for leaks in the fuel system.
Refer to this Operation and Maintenance Manual,
“Starting the Engine” for more information.
Priming the Delphi Fuel Injection Pump
for a Variable Speed Engine
1. Turn the keyswitch to the ON position and allow
180 seconds for the electric priming pump to prime
the system.
2. Turn the keyswitch to the OFF position and then
start the engine with the throttle in the closed
position. Operate the engine at idle with no load for
60 seconds and then shutdown the engine.
3. Wait 30 seconds and start the engine. This
procedure will remove any air that could be
trapped within the fuel injection pump. Check for
leaks in the fuel system.
Refer to this Operation and Maintenance Manual,
“Starting the Engine” for more information.
Priming the Delphi Fuel Injection Pump
for a Constant Speed Engine
1. Turn the keyswitch to the ON position and allow
180 seconds for the electric priming pump to prime
the system.
2. Turn the keyswitch to the OFF position and then
start the engine. Operate the engine with no load
for 60 seconds and then shutdown the engine.
3. Wait 30 seconds and start the engine. This
procedure will remove any air that could be
trapped within the fuel injection pump. Check for
leaks in the fuel system.
