any spillage of fuel immediately.
Disconnect the plastic tube assemblies (1). Plug the tube assemblies
with new plugs. Cap the open connectors (2) on the fuel priming pump
with new caps. Remove the primary filter (7) from the fuel priming pump
(4).
Remove the two setscrews (6) from the fuel priming pump (4). Remove the
priming fuel pump (4) from the mounting bracket. Remove the connectors
(2) from the fuel priming pump (4). Remove the plugs (5) from the fuel
priming pump (4). Remove the O-ring seals (3) from the connectors (2)
and the plugs (5). Discard the O-ring seals.

damage. If necessary, replace the fuel priming pump.
Install new O-ring seals (3) to the connectors (2) and to the plugs (5).
b. Install the connectors (2) to the fuel priming pump (4). c. Install
the plugs (5) to the fuel priming pump (4). d. Tighten the plugs and the
connectors to a torque of 20 Nm (14 lb ft).
Position the fuel priming pump (4) on the mounting bracket. Install the
two setscrews (6) to the fuel priming pump. Tighten the setscrews to a

Remove the plugs from the plastic tube assemblies. Remove the caps from
the connectors. Connect the plastic tube assemblies (1) to the
connectors (2). Ensure that the plastic tube assemblies are installed in
the original positions. Install a new primary filter (7) to the fuel
priming pump (4). Restore the fuel supply. Prime the fuel system.
Electric priming fuel pump
Isolate the fuel supply. Isolate the electrical supply. Disconnect the

(5) to a torque of 9 Nm (79 lb in).
Remove the plugs from the plastic tube assemblies. Remove the caps from
the electric priming pump. Connect the plastic tube assemblies (1) and
(2) to the electric priming pump (4). Ensure that the plastic tube
