1. Connect the 12" 6AN braided hose to the 6AN
fitting on the test gauge. Be sure to zero the gauge
before testing.
2. Based on the test jet selection instructions on
Page 1, insert the proper test jet in the outlet fitting
of the valve and attach the 4AN side of the 36"
hose to the valve.
3. With the fuel pump off and the pressure relieved
from the system, disconnect the outlet hose from
the fuel pressure regulator and connect the 6AN
hose from the gauge assembly to the pressure
regulator. Then securely run the 3AN outlet of the
36" hose back in to the tank or to a collection
container. Ensure the vale on the gauge assembly
is closed (black handle at 90° to the valve body).
4. Start fuel flow to the gauge by powering on your
fuel pump. Your flowing fuel pressure will be
displayed on the gauge when you open the shut off
valve. The display shows flowing fuel pressure in
large numbers, and highest recorded pressure in
smaller numbers on the bottom of the display.
5. Adjust the fuel pressure regulator to achieve
desired fuel pressure while flowing.
Note: While adjusting your fuel pressure, ensure
that your fuel system does not run low or out of
fuel. This can cause your fuel pressure to read
incorrectly and can cause irreversible damage to
your pump without fuel.
