Aeromotive 13159 User Manual

13101 / 13151 - 13109 / 13159 and 13114 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.

NOTE: Testing the enclosed regulator by applying air pressure or vacuum to the vacuum port with a
hand-held pump will yield poor results, due to the slight air leakage through the adjustment screw
threads. This minute leakage, which is typical of all adjustable fuel pressure regulators, does not, in any
way, affect the performance of the regulator.
The enclosed regulator will not necessarily seal to hold fuel pressure after the fuel pump stops running.

Part #13101, 13151 (Platinum Version) and 13114 (Marine Version) regulators utilize two o-ring
sealed ORB-10 inlet/outlet ports and one o-ring sealed ORB-06 style bypass or return port.

P/N #13109 and 13159 (Platinum Version) are equipped with all ORB-06 ports for inlet/outlet and
bypass/return connections.

ORB ports are NOT PIPE THREAD
fittings with o-rings, high pressure fuel lines and/or fuel injector rails to use this regulator. Each
regulator has one 1/8" NPT gauge port which does requires thread sealant to seal.

and utilize NO THREAD SEALANT. You must install ORB port

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.

This regulator features a vacuum/boost port and fitting in the cap which, if connected to your
intake manifold, will reference fuel pressure to manifold pressure. It works on a ratio of 1:1 with
PSI, raising fuel pressure with boost and reducing it with vacuum. If unused, please do not plug.

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, disconnect the negative battery cable and relieve the fuel

system pressure.

2. Remove any cosmetic covers necessary to allow access to the fuel pressure regulator.

3. Remove the vacuum line from the regulator (some vehicles do not have vacuum operated regulators).

4. Place shop towels around the regulator to catch any gasoline that is spilled during this step of the

installation. Remove any regulator mounting hardware and connecting fuel lines, then carefully
remove the regulator.

5. Find a suitable place in the vehicle’s engine compartment to mount the Aeromotive regulator. Using

the supplied mounting bracket as a template, mark the bracket mounting holes and drill to accept a
#10 screw.

6. With the bracket attached to the regulator, mount the bracket and regulator to the vehicle using two

#10 screws, nuts and lock washers.

7. Attach the fuel line(s) from the fuel rail outlet port(s) to the regulator side ports using AN-10 (AN-06 if

regulator is Aeromotive P/N 13109 or 13159) style fittings and o-rings. If only one inlet/outlet port is
required (see figure 1-3 below) install an AN-10 style port plug with o-ring (AN-06 if regulator is
Aeromotive P/N 13109 or 13159) into the unused port.
