Note: Test all fittings and hoses for any leakage. If any leaks are detected, determine the
cause of the leak and repair. Do not operate the vehicle if any leaks are detected.
Electrical Section
For maximum electro-luminescent life, do not wire lighting to direct igntion switched 12-
volt source. The lighting power source should be routed through OEM dash controls, or a
separate rheostat. Power can be achieved by tapping into the factory dash lighting through
either the fuse panel or from a 12-volt dash light wire. This will allow you to control the
light intensity. Use the appropriate connectors for your particular application. The white
wire must be connected to the power source and the black wire to a good ground. Damage
to electronic circuits could occur if connected incorrectly.

3. Route the pressure line through the grommets to the engine compartment.
Connect the line to a tee fitting plumbed in line with the fuel line. Be sure
to use liquid Teflon sealant on all tapered pipe threads for a good seal. No
sealant is required on AN flare fittings. Also make sure that the pressure
line is routed away from any sources of heat or moving components.
4. If you choose to use either the green or red light bulb cover, install this over
the bulb in the light fixture for the gauge and install the fixture into the
gauge by simply pushing the light fixture into the hole on the back of the
gauge until the fixture snaps into place.
