Before you drive
Diamondback Propane is listed on our Phoenix, AZ propane refill guide under Mesa/East Valley. This page is the station detail view: call and maps first, then the published facts we captured from the public source page. We do not invent hours, phones, or prices — if a field was unknown on the source, it stays unknown here.
Refill vs exchange: a refill puts propane into the tank you own (billed by gallon or weight). An exchange cage swaps tanks for a flat fee and is usually limited to 20-lb grill cylinders. If a Maps pin is only a locked cage with a card reader and no fill equipment, you are in exchange territory.
What to bring: the empty (or low) cylinder you own; a readable collar with manufacture/requalification dates; an OPD valve on cylinders through 40 lb propane capacity; and a tank free of heavy rust, dents, bulges, or a damaged foot ring/collar. Out-of-date or damaged tanks are commonly refused. Legal fill leaves vapor space (~80%); expect a partial “full,” not a brick-solid cylinder.
Gallon prices and live attendant coverage change — omitted on purpose. Use Call first, then Maps. Spot a closed yard or wrong hours? Report closed / wrong hours.
