And how does it arrive?** A: Mine was shipped to VA from the west coast and arrived about 2 1/2 weeks after I ordered it. Came in a box truck with a lift gate. Paperwork said "threshold delivery". **Q: What is the return policy on this item?** A: Shipping a tank like this could run from $400-$1000 depending on where you are and where the tank needs to be returned. You'll be stuck with the tank and will have to try to re-sell locally to come close to break even. **Q: Can this tank be buried? Our town doesn't allow aboveground propane tanks, but we don't need a larger one than this.** A: Burial tanks are made differently, they have special paint on them and need protection from electrolysis in the ground. You should definitely call a local propane professional for a burial tank. In western WA a burial 250 gallon tank is $6,500 installed. 500 gallon tank is $8,950 installed. **Q: Connection diameter what size hose should i use to connect to the vapor outlet 3/4', 3/8" or 1/2"?** A: It takes a 1/4" line to the regulator, which should be mounted under the lid. I bought a 12" and bent it into a circle using a Husky tubing bender, keeping the regular protected from the weather. The low pressure line size after the regulator is determined by the number of BTUs that your connected equipment requires. I bought a Rego 2 stage regulator that has a 1/2" output but downsized it to 3/8" since only feeding one grill and a fireplace. ## Frequently Bought Together - Flame King YSN420ASME 420LB (120 Gallon) ASME Vertical Steel Propane Tank, White - Marshall Regulator Home Propane Supply Kit LP 1122H-AAJ 1652-CFF 3/4" Backmount - Emerson-Fisher LP-Gas Equipment R622-DFF 2nd Stage Regulator, 9-13" W.C Spring, 3/4" x 3/4" NPT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/462520829-flame-king-ysn420asme-420lb-120-gallon-asme-vertical-steel-propane](https://www.desertcart.vu/products/462520829-flame-king-ysn420asme-420lb-120-gallon-asme-vertical-steel-propane) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
