Jeep CJ 1945-1970 Repair Information

Tank Assembly



1945-69 Models

See Figures 1 and 2

  1. Make sure that the tank is either completely drained or that the level is at least below any of the vent lines or filler openings so that when these lines are disconnected fuel will not run out.
  3. Remove the driver's seat from the vehicle.
  5. Disconnect all of the vent line hoses, the fuel gauge electrical lead, the fill hose and the fuel outlet line at the tank.
  7. Remove the tank hold-down screws from the mounting brackets, or the hold-down strap, and lift the tank from the vehicle.
  9. If there is still gas in the tank, be careful not to spill any fuel when lifting it out of the vehicle. Also, empty the tank of all fuel and flush it with water before soldering or welding the tank.
  11. Install the tank in the reverse order of removal.

1970 Model

The fuel tank is attached to the frame by brackets and bolts. The brackets are attached to the tank at the seam flange or the skid plate.

Before removing the fuel tank, make sure that the level of the fuel inside the tank is at least below any of the various hoses connected. It is best to either drain or siphon the majority of fuel out of the tank to make it easier to handle while removing it.
