Aeromotive 11156 INSTALLATION INSTRUCTIONS

AEROMOTIVE

Part # 11103 & 11106

INSTALLATION INSTRUCTIONS

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.

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.

The enclosed Aeromotive fuel pump utilizes o-ring sealed AN-08 style inlet and AN-06 outlet ports; these ports are NOT
PIPE THREAD and utilize NO THREAD SEALANT.

A high capacity, 100 micron fuel filter must be installed between the fuel tank and pump inlet. We recommend an
Aeromotive p/n 12304 filter. Call us for info.

The enclosed Aeromotive fuel pump does not utilize a check valve on the pumps outlet. If your application requires a
check valve on the fuel pump outlet please order Aeromotive p/n 15106.

To use this pump in your vehicle’s fuel system, we strongly recommend the following

A by-pass style fuel pressure regulator must be used in the system.
Gravity feed the pump by mounting it lower than and as close as possible to the fuel tank.
If you are using a stock fuel tank, install a reservoir style sump in the bottom-rear of your fuel

tank. Exercise extreme caution and follow all manufacturer’s recommendations when
installing a reservoir style sump.

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

fuel tank pickup.(Installing a high flow pickup instead of a reservoir style sump may
shorten the fuel pump life and cause driveability problems. Stock fuel tanks have a small
inlet reservoir that is quickly emptied by a high flow fuel system, causing pump starvation
and cavitation. When using a pickup, you should maintain at least ½ tank of fuel in the

vehicle at all times, to avoid emptying the stock inlet reservoir.)
Utilize AN-08 size high pressure fuel lines, fittings and o-rings for all connections from the
fuel tank pickup to the fuel rails in the engine compartment. (Call Aeromotive for availability.)

Failure to follow the above recommendations 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!

Aeromotive system components are not legal for sale or use on emission controlled motor vehicles.

:

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 high flow capacity fuel tank pickup, 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, 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.

6. Using the bracket 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.

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.

7. Connect the fuel tank pickup to the fuel filter inlet and the fuel filter outlet to the fuel pump inlet. The inlet side of the
fuel pump is where most fuel system problems occur; it is important to minimize any restrictions in this area.

8. Connect the fuel pump outlet to the vehicle’s fuel rails in the engine compartment. See figure 1 for recommended
system plumbing. Make sure you use high pressure(150 psi minimum) fuel line for this connection!
