8. Position power cable (6c) so the large diameter of
power cable extends through strain relief (6b).
9. Tighten nut on strain relief to form a seal around the
power cable.
10. Reinstall electrical cover (2a) on the pump.
11. Remove 1/2 in. (13 mm) of insulation from wires on
the fuse holder end of the power cable.
12. Attach battery clamps (6a) with red sleeve to red
wire and black sleeve to black wire. Wire must be
crimped to the battery clamp firmly to get a good
electrical connection.
13. Connect red wire with fuse holder inline to positive
battery terminal. Connect black wire to negative bat-
tery terminal.
Electrical Installation
115 VAC and 230 VAC
On 115 VAC and 230 VAC pumps, electrical connec-
tions must be made by a licensed electrician per
requirements of local, state, and national codes
regarding class 1, group D installations. Only rigid
conduit with threaded connections should be used.
Conduit opening in pump must be sealed with
waterproof, fuel-resistant sealant. Failure to comply
with this warning could result in injury from electrical
shock.
1. Ensure pump switch is OFF and electrical power is
disconnected.
2. Install conduit and user-supplied power cord to
pump.
3. Strip 3 in. (76 mm) from power cord jacket and 1/2
in. (13 mm) from individual conductor insulation.
4. To remove electrical cover (2a), remove four bolts
(2c).
5. Remove 1/2 in. (13 mm) of insulation from power
wires inside pump electrical terminal cavity.
6. Insert electrical power wire through conduit opening
in back of pump.

7. Using wire nuts (2e), connect wires: green to green,
white to white, and black to black.
8. Replace electrical cover.
Priming Pump
1. All pump models will prime with no fluid in the
pumping chamber to a height of 5 ft (1.52 m). If
pump fails to prime, remove hose from street elbow-
fitting on pump outlet and pour 8 oz (0.24 liter) of
motor oil into the pump outlet port.
2. If suction height is too great, the pump may lose its
prime if the nozzle is opened with the pump turned
off.
3. To hold fluid in the suction tube, a check valve
(Graco Part No. 260217) may be required on the
bottom of tanks with a suction height over 5 ft (1.52
m).
4. The tank must be vented or the pump may not prime
or may lose its prime due to a vacuum in the tank.
