Fuel system fit-up
A steel 15 gallon tank is a durable choice for a CJ5 or CJ7, but the fit around it matters as much as the tank itself. The inlet and filler neck sizes determine which hoses and clamps are needed, so these should be confirmed before the old tank is removed. Steel also needs the seams and mounting points checked for rust before installation.
Before fitting, clean the inside of the new tank of any shipping debris and check the straps and skid area on the vehicle. Replacing the filler hose and vent lines while the tank is out is a sensible step, since these parts are reached during the same work.
- Confirm hose and clamp sizes before removal
- Clean the tank interior before fitting
- Inspect the straps and skid area for rust
