My go to tank for generator use
My experience with the Flame King YSN401b 40 Pound Steel Propane Tank has been nothing but positive. I was on the hunt for a reliable propane tank and decided to give this one a go, and I'm so glad I did! Right off the bat, the OPD (Overfill Prevention Device) Valve instilled confidence in terms of safety during both use and refilling processes. This feature alone, which helps to prevent overfilling, adds an extra layer of security thatโs incredibly reassuring. The white exterior has proven to be resilient against weather conditions and hasnโt shown signs of wear or rust even though it's stored outside. Refilling it has been a breeze, and I've found that it holds the propane reliably without any concerning leaks or issues. The 40-pound capacity has been adequate for our usage, ensuring weโre not constantly needing to refill it, which has been especially convenient. Overall, the Flame King Propane Tank is sturdy, reliable, and gives me peace of mind knowing that safety is prioritized with the OPD Valve. Iโm very pleased with this purchase and would recommend it to anyone in need of a high-quality, dependable propane tank."

Well made
I have a dual-fuel 13kW generator that can operate on gasoline or propane, and I want to always have fuel on hand to run it in case of an emergency. I'm not interested in storing gasoline long-term, but propane is very easy to store. I've picked up a couple of these propane tanks and I have them filled at Tractor Supply, and then I store them outside on the porch. They're solidly made with good, tight valves that come with a dust cover for protection when not in use. They can be a little awkward to lift or move around when they're full if you're not accustomed to that, but i have a couple of them so I'm used to it. With a tank this size, my generator can run most all day at half load. I'll probably pick up a couple more of these.

Nice tank at a fair price.
Got this for my Generator and so far no problems. Itโs mainly a standby tank in case of a power outage.

Bigger propane storage grill/generator
New tank with quality OPD and construction. Solid finish and design. Great for increased capacity storage and generator use. Has standard quick connect for hand tighten adapter from your grill or generator.

No Markings
The tank arrived in good shape... I am curious, is it normal for the tank to not have any labelling? IE, there is nothing on the tank that alludes to it being a Flame king tank. This bothers me a little as this could be a Non-Flame King tank and how would you know? It came with an inspection sticker on the handle that states purged and ready for filing and a sticker that states it has overfill protection. That's it folks... Confused here...
