Does this tank come ready to use, or do I need to clean or seal it first?

The polished finish is factory-ready. Before filling, flush the tank with clean fuel or a fuel system cleaner to remove any manufacturing residue — standard practice for any new fuel cell.

What mounting hardware do I need to install this tank?

The tank and sender are included, but mounting straps, fuel line fittings, and fasteners are not. You'll need to source those based on your vehicle's frame and plumbing layout.

Will the level sender work with my stock fuel gauge?

The sender is a standard unit, but compatibility depends on your vehicle's gauge resistance specs. Check your owner's manual or service data for the correct ohm range — some gauges require calibration or a dedicated fuel gauge module.
