Fuel Priming Pump - Remove
and Install
Removal procedure
There are two types of fuel priming pump. Type 1 is
mounted above the starter motor. Type 1 is combined
with the fuel filter. Type 2 is mounted below the
starter motor. Type 2 is not combined with the fuel
filter. Type 2 is used on 4 cylinder engines only.
Removal Procedure for Type 1
Start By:
a. Remove the assembly of the filter case and the
fuel filter element. Refer to this Disassembly and
Assembly Manual, "Fuel Filter Base - Remove
and Install".
Note: There is an option for the three cylinder
engine. The fuel priming pump and the fuel filter can
be installed onto the application rather than onto the
engine. If this is the case, refer to the appropriate
installation manual that is supplied by the OEM for
further information.
Note: Put identification marks on all fuel hose
assemblies and on all tube assemblies for installation
purposes. After being disconnected, plug all fuel
hose assemblies and plug all tube assemblies. This
helps prevent fluid loss, and this helps to keep
contaminants from entering the system.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to

ing any compartment or disassembling any compo-
nent containing fluids.
