Aeromotive 11259 - PLATINUM SERIES H_0 FUEL PUMP - 3_8 NPT - Manual (Page 2)

The following steps are typical of most installations:
1. Once the engine has been allowed to cool, disconnect the negative battery cable and relieve the fuel
system pressure.
2. Disconnect the existing pump fuel lines. Plug the open fuel line ends and remove the existing pump.
3. Find a suitable place on the vehicle chassis to mount the Aeromotive fuel pump. Make sure the
location will accommodate the pump mounting bolts, will position the pump lower than the fuel tank, is
clear of the exhaust, is clear of any moving suspension or drivetrain components and will keep the
pump clear of road obstructions or debris.
4. Making sure to mount the pump in the upright position and using the pump mounting bracket as a
template, mark and drill two mounting holes to accept ¼” bolts. Mount the pump bracket using two ¼”
bolts, nuts and lock washers. Slide the pump into the bracket and tighten the clamping bolt. Do not
over-tighten the clamping bolt. Doing so can permanently damage the pump motor!
Note: Be sure to route all fuel lines clear of any moving suspension or drivetrain components,
and any exhaust components! Protect fuel lines from abrasion and road obstructions or debris.
5. Connect the fuel tank or cell to the high capacity 100 micron filter. Connect the filter outlet to the 3/8
NPT fuel pump inlet(see Flow arrow on pump). These sections of fuel line should be as short as
possible to reduce the tendencies for vapor lock, cavitation, and premature wear of your Aeromotive
fuel pump.
6. Connect the 3/8 NPT fuel pump outlet to the inlet of your 10 micron fuel filter and the fuel filter outlet
to your fuel line. Connect the other end of the fuel line to the carberetor in the vehicle’s engine
compartment.
Note: Be sure to route all electrical wires clear of any moving suspension or drivetrain
components and any exhaust components! Protect wires from abrasion and road obstructions or
debris.
7. Connect electrical power (12 VDC) to the pump. Make sure you use stranded, insulated copper wire,
in the sizes shown, with matching crimp-type connectors for all connections. CAUTION: The pump
must not be connected directly to the battery. Connect the green wire from the fuel pump to a
switched +12 volt source and the black wire to a clean ground as shown in the following diagram:
8. Attach a suitable fuel pressure gauge to the fuel system.
9. Ensure that any spilled fuel and any fuel soaked shop towels are cleaned up and removed from the
vicinity of the vehicle.
