Install Instructions for 10-1017

Before You Start

  • Please read the entire product guide before proceeding
  • Ensure all parts are present.
  • If you are missing any parts, please call or text us at (909)-675-1313
  • Do not work on your vehicle while the underbody components are hot.
  • Make sure the vehicle is in park or the parking brake is set if you plan on working on the ground. If working on a lift, make sure the vehicle is lifted safely and securely.
  • In-bed Auxiliary Fuel Tanks will void the Lifetime Warranty.
  • Drain your original fuel tank before beginning the S&B Installation process. S&B Tanks recommends removing only an empty or near empty tank for your safety. We recommend using a siphon or electronic transfer pump.
  • Disconnect and isolate both of the negative battery cables
  • Before installing S&B Tank, conduct pressure test to ensure o'ring is properly seated.
  • Installs with an aftermarket lift pump: Aftermarket lift pumps installed on with S&B Tanks should be installed according to the lift pump manufacturers recommendation. If the sending unit is modified for the install of the lift pump, please note that the sending unit flange will be under the fuel level on the S&B Tank so if you don't have a good seal with the aftermarket lift pumps parts, then you will have a leak.
  • Installs with a Fleece in tank lift pump: The Fleece lift pump comes with a small port on the side of the flange. This will need to be blocked off.
