Aeromotive 13220 User Manual

13220 EFI-To-Carb Dual Regulator
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: The enclosed regulator will not necessarily seal to hold fuel pressure after the fuel pump
stops running. In addition, testing the enclosed regulator by applying air pressure or vacuum to
the vacuum/boost port with a hand-held pump will show a slight air leakage through the
adjustment screw threads. This leakage is minute and is typical of all adjustable fuel pressure
regulators. This does not, in any way, affect the performance of this regulator.
The Aeromotive regulator, Part #13220, utilizes three 3/8” NPT inlet/outlet ports, and one 3/8” NPT
bypass or return port. The regulator also has three 1/8" NPT gauge ports. All NPT ports require
the use of thread sealant equivalent to Loctite 565 for proper sealing.
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

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.
