Instruction Manual
Fuel Tank Installation:
1. Once you’ve installed the fuel level sender and fuel pump, you’re ready to proceed with installation
of your Sniper EFI Fuel Tank.
2. Remove the OEM fuel filler neck and replace with the suppled piece.
3. Raise the assembled Sniper EFI fuel tank into place ensuring all hoses, electrical connections, etc.
are out of the way.
4. Once in place, secure the fuel tank with the supplied fuel tank straps and reinstall the OEM front
fuel tank bracket.
5. Check that the fuel tank is securely installed. The tank should have no movement in any direction.
6. Clean/Flush all fuel line/hoses to remove any dirt and debris.
7. Install the fuel filler neck, EVAP hoses, electrical connections, fuel lines, etc. Be sure to fully tighten
all connections.
8. Reinstall the driveshaft.
9. Lower the vehicle.
10. Turn the fuel pump ON without starting the engine by turning the ignition key to the “ON”
position, allow the pump to run for several seconds and check the fuel pressure gauge (if
applicable). If there is no pressure, turn the fuel pump OFF, wait one minute, then turn the fuel
pump ON and recheck the pressure. Repeat this fuel pump OFF and ON procedure until the fuel
pressure gauge registers pressure or you detect a fuel leak.
11. It may be necessary to loosen the fuel line fitting at the pressure regulator to bleed off excessive air
in the system. Tighten any fuel line fittings which where loosened and insure that any spilled fuel is
cleaned up and removed from the vicinity of the vehicle. If no pressure is registered on the gauge
after running the pump for several seconds and you have found no leaks, check all fuel and
electrical connections to determine the cause.
12. Test drive the vehicle to insure proper operation and re-check the fuel system for leaks. If any
leaks are found, immediately discontinue use of the vehicle and repair the leak(s)!
