identified by the “N2O” marked on the plate. Repeat this procedure for the red fuel line (the fuel fitting
will be marked “FUEL”). NOTE: Always check each jet for obstructions before installing.

FUEL SUPPLY CONNECTION:
WARNING: THE FUEL RAIL AND/OR FUEL LINES ARE UNDER HIGH PRESSURE. USE
EXTREME CAUTION WHEN DISCONNECTING ANY FUEL LINE. QUICKLY COLLECT AND
PROPERLY DISPOSE OF ANY EXCESS FUEL SPILLAGE.
1. Located on the fuel log (injector rail) is a “test port” fitting used by mechanics for checking fuel
pressure. This is usually covered by a black plastic cap and is where the red fuel feed line will be
connected. Note: Care should be taken to be certain the port you have selected is the “Fuel Test-Port”.
Many late model cars have several similar ports that do not contain fuel.
2. Remove the protective cap from the test port fitting. Using a valve core wrench, (valve stem core
remover) remove the inner core from the test port fitting. (Recommend using a proper mechanics
shop rag over the fitting to avoid excess fuel spillage). Check thread compatibility with AN fitting on
red stainless fuel line.
3. If you are using aftermarket fuel rails you may be required to use a “T” fitting to tap into your vehicles
fuel system. ONLY TAP INTO THE HIGH PRESSURE FUEL LINES! DO NOT TAP INTO A
RETURN LINE!
4. Now connect the red fuel line from the fuel supply to the inlet side of the fuel solenoid.
