Aeromotive 11110 INSTALLATION INSTRUCTIONS

11104 & 11110 Installation Instructions

WARNING!

The fuel system is under pressure. Do not open the fuel system until the pressure has been relieved.
Refer to the appropriate vehicle service manual for the procedure and precautions for relieving the fuel system
pressure.

To use this pump in your vehicle’s fuel system, you must do the following

• A by-pass style fuel pressure regulator must be used in the system.

• Utilize AN-12 size high pressure fuel lines, fittings and o-rings for all connections from the fuel

tank pickup to the fuel pump.

• Mount pump level or lower and as close to the bottom of the tank as possible.

• Install a 12302 pre-filter and 12310 post filter.

• If you are using a stock fuel tank, install a reservoir sump in the bottom-rear of your fuel tank.

Exercise extreme caution and follow all manufacturers’ recommendations when installing a

reservoir sump. (Sump part # 15650)

• Tank/Fuel cell must have at least a ½” tank vent.

• If you choose not to install a reservoir sump, then you must install a high flow capacity fuel

tank pickup (3/4” inner tube diameter). (Installing pickup instead of a reservoir sump may

shorten the fuel pump life and cause drivability problems. When using a pickup, you should

maintain at least ½ tank of fuel in the vehicle at all times, to avoid possible engine & or fuel

pump damage.)

• For any street driving or continuous use, Aeromotive recommends the installation of a pump

voltage control module, Aeromotive p/n 16306 (not needed for marine use).

Failure to follow the above may result in fuel leakage, bursting of the fuel lines, poor vehicle
performance and/or decreased fuel pump life! Improper installation will void all warranties for this
product!

CAUTION:

:

Installation of this product requires detailed knowledge of automotive systems and repair procedures. We
recommend that this installation be carried out by a qualified automotive technician.

Installation of this product requires handling of gasoline. Ensure you are working in a well ventilated area
with an approved fire extinguisher nearby. Extinguish all open flames, prohibit smoking and eliminate all sources
of ignition in the area of the vehicle before proceeding with the installation.

When installing this product, wear eye goggles and other safety apparel as needed to protect yourself
from debris and sprayed gasoline.

The enclosed Aeromotive fuel pump utilizes an o-ring sealed AN-12 style inlet and an AN-10 style outlet port; these ports
are NOT PIPE THREAD and utilize NO THREAD SEALANT.

The following steps are typical of most installations:

1. Once the engine has been allowed to cool, relieve the fuel system pressure and disconnect the negative battery cable.

2. Raise the vehicle and support it with jack stands.

3. Referring to the appropriate vehicle service manual for instructions, remove the OEM fuel pump.

4. Install an after-market fuel cell or fuel tank sump kit, per the manufacturer’s instructions.

Note: Failure to mount the pump lower than and close to the fuel tank may cause the pump to run dry, resulting in
extreme pump wear! Make sure the pump is located lower than and as close as possible to the fuel tank, so that
the pump is always supplied with fuel!

5. Find a suitable place on the vehicle chassis to mount the Aeromotive fuel pump. Make sure the location will

accommodate the pump mounting bolts, 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. Using
the pump as a template, mark and drill four mounting holes to accept ¼” bolts. Mount the fuel pump using four ¼”
bolts, nuts and lock washers. For quieter fuel pump operation use Aeromotive p/n 11601 fuel pump vibration
dampening mounting kit.

6. Using minimum of 3/4” ID or AN-12 fuel line, connect the fuel tank sump outlet to a 12302 fuel filter. Using the same

size fuel line connect the fuel filter outlet to the fuel pump inlet, or if you are using an Aeromotive fuel filter you can
attached the filter directly to the fuel pump utilizing an AN-12 fitting (15612) and 2 sealing o-rings (12AN o-ring pack

15624).
