Replacing a gas tank on a 1993 Chevrolet Suburban can be a challenging task if you are not prepared. When working with fuel, you must take extra precaution and care in order to avoid accidents. Work in a well-ventilated area and keep your space free of heat and sparks. It is a good idea to have a fire extinguisher nearby, and wearing gloves is recommended. A repair manual, such as Haynes or Chilton, will come in handy when working on your own vehicle.
Tools Used: Tools, Socket set, Torque wrench, Shop rags, Siphoning kit, Fuel container, Jack, 2 jack stands, Transmission jack, Latex gloves (optional), Safety mask (optional), Class B fire extinguisher (optional)
Remove the Gas Tank
Prepare your work area by having all the tools you will need within easy reach. Disconnect the negative side of the battery. Carefully raise the back of the vehicle and support it securely with jack stands.
Remove the fuel cap and remove all the fuel from the tank with the siphoning kit. It is recommended that you use latex gloves when working with fuel. Fuel should be placed in a fuel container and placed in safe place away from sparks and heat. If your fuel tank is covered with a fuel tank shield, remove it.
Then disconnect the clamp from the fuel filler pipe near the fuel tank and separate the filter pipe. Disconnect the fuel pump harness connectors from the pump. Disconnect the fuel supply and return lines. Position a transmission jack under the fuel tank and support the tank.
