The following assembly instructions will assist you in installing the tank, fuel level sender, and the fuel pump
module to complete your installation.
WARNING! THESE INSTRUCTIONS MUST BE READ AND FULLY UNDERSTOOD BEFORE BEGINNING
INSTALLATION. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN POOR
PERFORMANCE, VEHICLE DAMAGE, PERSONAL INJURY, OR DEATH. IF THESE INSTRUCTIONS ARE
NOT FULLY UNDERSTOOD, INSTALLATION SHOULD NOT BE ATTEMPTED. PLEASE CONSULT

Please use caution draining and removing your old tank. Gasoline is very flammable. Do not smoke or have
any heat sources near your work area.
OEM Fuel Tank Removal:
1. Begin by disconnecting the battery.
2. Drain the fuel tank of as much fuel as possible before attempting to remove as the fuel tank will be
exceptionally heavy and dangerous to work with if it is half a tank or more.
3. Securely lift vehicle. If a vehicle lift is not used, secure the vehicle with jack stands.
4. Remove driveshaft from vehicle. If your vehicle is equipped with a slip yoke style drive shaft, ensure
that you have a way of capping the transmission off or the transmission fluid will leak out.
5. Safely depressurize the fuel system ensuring no fuel spillage occurs. WARNING! Be aware of hot
components such as the exhaust system. Do not smoke or be near any sources of flame or
spark.
6. Disconnect all electrical connections and hoses including the fuel filler neck from OEM fuel tank.
