WHEN USING RETURN STYLE REGULATORS
(See Figure 1)
Step 1
Release the jam nut on the bypass plug. Remove the
bypass plug. Remove the bypass spring and plunger.
Discard the bypass spring.
Step 2
Inspect the bypass plunger. The bypass plunger surface
should be clean and slide freely in the chamber. Check the
bypass plunger pad and remove any debris embedded in
its surface.
Step 3
Install the bypass plunger pad in the bypass plunger. Install
the bypass plunger and bypass spacer. Clean the bypass
plug.
Step 4
Apply thread sealant compound on the bypass plug. You
can find thread sealant compound at a hardware store. Do not use Teflon tape.
Step 5
Install the bypass plug. Gently tighten bypass plug until you feel it lock (torque to 5 in/lbs). Install and
tighten the jam nut.
MOUNTING PROCEDURE
The regulator is ready for installation in applications
requiring 3-12 PSI fuel pressure ranges.
APPLICATIONS REQUIRING FUEL PRESSURE
RANGING FROM 10-65 PSI (See Figure 2)
Step 1
Remove the four regulator cap screws and regulator cap.
Step 2
Interchange the medium spring and spring spacer/washer
for 10-40 PSI fuel pressure ranges. Interchange the
medium spring, large spring, and spring spacer/washer
for 35-65 PSI fuel pressure ranges.
Step 3
Install the regulator cap and the four regulator cap screws.
Torque regulator cap screws to 20 in/lbs.
The regulator may be mounted at any angle. For maximum efficiency, mount the regulator as close
as possible to the carburetors or fuel injection systems. DO NOT mount the regulator on or near
exhaust manifolds. A bracket is provided for convenient mounting under an intake bolt.
