INSTALLATION INSTRUCTIONS
Fuel Pump Installation (Camaro, Firebird)
Warning: Before performing any of these steps, relieve the pressure in the fuel system.
1. Locate the fuel filter on the under-carriage of the car. Disconnect the
hard fuel line from the filter.
2. Install the male O-Ring to -6AN male adapter fitting into the outlet of
the fuel filter.
3. Mount the fuel pump to the under-carriage of the vehicle. Cut the
supplied fuel line to size as pictured.
4. Install the hose fittings and tighten all hoses down with the supplied
hose clamps.
5. Install the female O-Ring to -6AN male adapter to the end of the steel
fuel line. Secure fitting to hose with supplied hose clamp and connect
hard fuel line to this fitting. Check the fuel system for leaks by turning
the ignition key to the “On” position. Do not start the engine
. Inspect all fittings and lines for leaks. Also check wires from
time to time for damage or leaks.
Fuel Pump Installation (Impala)
Warning: Before performing any of these steps, relieve the pressure in the fuel system.
1. Locate the fuel lines under the vehicle. These should be 2 black plastic
lines located on the driver’s side of the vehicle by the frame rails.
Determine which line is the main feed line by following them back to
the fuel filter.
2. Determine the mounting location of the fuel pump and mount the
pump. Be sure the pump will be mounted above the lowest parts of
the car and out of danger from road debris. The pump must be
mounted between the fuel filter and engine.
3. Be sure where you decide to cut the line is close to the booster pump.
Cut the plastic fuel line using a sharp razor blade or other similar
cutting tool.
