FUEL SYSTEM INSTALLATION
1.
Drain the fuel tank.
2.
Remove all fuel lines from the tank and from the carburetor.
3.
Remove the fuel tank.
NOTE: While the fuel tank is removed from the car, it is recommended that it be
professionally cleaned in order to remove any rust or dirt that may have accumulated
inside and which could damage the injectors.
4.
Remove the sending unit from the fuel tank. Refer to the RETURN FUEL LINE methods
above for installing the bypass fuel return line.
5.
Install the provided 3/8-inch primary fuel line directly above the original line, which may
now serve as a return line. Use large radius bends. Avoid the exhaust pipe and any
sharp edges.
NOTE: The 3/8-inch high pressure fuel line supplied with the Pro-Flo system must be
used as the primary fuel line.
6.
If you do not use the original fuel as the return line, route the return line directly
alongside the provided 3/8-inch primary fuel line.
NOTE: In the application shown to the right, we routed our fuel supply and return lines
down the passenger side of the engine and along the passenger side frame rail.
7.
Mount the fuel pump between the tank and the fuel filter as low and as close to the fuel
tank as possible. The pump is directional. Electrical connectors should face the front of
vehicle. The fuel pump needs to be at or below the level of fuel in the tank.
8.
Mount the fuel filter between the fuel pump and the engine.
9.
Re-install the modified sending unit plate to the clean fuel tank.
10. Re-install the fuel tank.
11. Attach the primary line and return line to the sending unit plate on the tank.
12. Re-attach all other fuel lines at the tank (vapor purge lines, etc., if so equipped).
13. Secure the primary and return fuel lines with the provided tie-wraps, or with Adel clamps
if available.
14. Re-attach all fuel lines to the induction system once it has been installed.
15. Use the 10-foot wiring harness to connect the fuel pump to the Main System Harness.
Route the harness away from the exhaust pipe and any sharp edges. This harness may
be cut to length. Replacement terminals are provided with the Pro-Flo system. Cover
the connection to the positive terminal with the sleeve and tie wrap provided. Refer to
the MAIN SYSTEM HARNESS section of this manual for details.
16. Before starting the engine, turn the ignition key to the “ON” position 4 or 5 times to
prime the electric fuel pump, fuel lines, and fuel rails. You should hear the pump run for
approximately 2 seconds each time. Check the entire fuel system for leaks. Refer to the
SYSTEM START-UP section of this manual for details.
