Part # 13212
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 may be under pressure. Do not open the fuel system until
any 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 handheld 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 enclose Aeromotive regulator utilizes 2 o-ring sealed AN-10 style supply ports, and one o-ring
sealed AN-10 style bypass port (This port requires a cutoff AN-10 style fitting Aeromotive P/N
15608 or equiv.); these regulator ports are NOT PIPE THREAD
The enclosed Aeromotive regulator is designed to be used with high flow (300 gph minimum), low
pressure fuel pumps similar to Aeromotive P/N 11202. Performance may be degraded if a similar
pump is not used.
The Vacuum / Boost reference port is provided for fuel pressure compensation at a 1:1 rate, this is
primarily used in blow-thru centrifugal supercharged applications or factory EFI vacuum
referenced regulators. In most cases this port is left open to reference atmospheric pressure.
Aeromotive system components are not legal for sale or use on emission controlled motor vehicles.
The following steps are typical of most installations:
and utilize NO THREAD SEALANT.
1. Once the engine has been allowed to cool, disconnect the negative battery cable and relieve any fuel
system pressure.
2. 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.
3. 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.
4. With the bracket attached to the regulator, mount the bracket and regulator to the vehicle using two
#10 screws, nuts and lock washers.
5. Attach the fuel log or fuel supply lines to the AN-10 ports located on either side of the regulator using
AN-10 style fittings and o-rings. Block unused ports using a AN-10 port plug and o-ring.
2x AN-10 Supply Ports
6. Attach the fuel return line to the AN-10 bypass port located at the bottom of the regulator using a
cutoff AN-10 style fitting (Aeromotive P/N 15608 or equivalent) and o-ring.
AN-10 By-Pass Port
7. Tighten all connections.
8. Once the regulator is installed, attach a suitable fuel pressure gauge in the fuel system.
9. Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and
removed from the vicinity of the vehicle!
10. Reconnect the battery and turn the fuel pump ON WITHOUT starting the car. After several seconds,
check the fuel pressure. If there is no fuel pressure, turn the fuel pump OFF, wait one minute, return
the fuel pump ON, and recheck the fuel pressure. Repeat this OFF and ON procedure until the fuel
pressure gauge registers fuel pressure.
