Does the level sender work with my existing fuel gauge?

The sender is a standard unit; it connects to most aftermarket and OEM gauges via the fuel level wire. Verify your gauge accepts a standard sender before installation to avoid compatibility issues.

Will the polished finish stay looking new, or does it need maintenance?

Polished aluminum will oxidize and dull over time with exposure to fuel vapors and road elements. A clear coat or periodic polishing keeps the shine, but it's not maintenance-free. Many buyers accept the patina as part of the look.

What do I need to mount this tank in my car?

Mounting hardware and method are not specified with this tank. You'll need to determine your vehicle's setup—straps, brackets, or custom fabrication—before ordering. Measure your engine bay and plan your fuel line routing in advance.
