How propane refill works at U-Haul
Updated October 24, 2026
U-Haul is the largest single refill network in the public station list, with more than a thousand stores that fill propane. They are also the most consistent: the process is the same at every store, and most are open seven days.
What they fill
- 20 lb, 30 lb, 40 lb and 100 lb cylinders, as long as the tank is within its date and has an OPD valve where one is required.
- RV and motorhome tanks, both removable cylinders and fixed ASME tanks. Pull up to the fill station; the attendant comes to the vehicle.
- Forklift cylinders.
- Autogas vehicles at stores with a quick-connect nozzle. The finder marks those with the “Autogas” label.
How it works
- Go inside and ask for a propane fill. The attendant has to be propane-certified, so at busy times you may wait for the right person.
- The attendant takes the cylinder to the fill station outside, checks the date stamp and valve, and fills it by weight.
- You pay inside for the gallons dispensed. A 20 lb tank that was empty takes about 4.7 gallons.
The price is per gallon and is set by the store. It is usually posted at the fill station and is not listed online. If you paid for a fill, report the price so others can see the going rate in your state.
Hours
U-Haul stores keep retail hours, typically 7 am to 7 pm on weekdays, shorter on Sunday. Propane filling stops a few minutes before close. Hours on each station row come from the Department of Energy’s listing and may lag; the phone number on the row reaches the store.
Tanks they turn away
- Past the 12-year requalification date on the collar. See expired tanks.
- No OPD valve. See the OPD valve.
- Visible damage: deep rust, dents, a bent guard.
Expired or old-valve tanks can go to an exchange cage instead.
Finding one
Search your ZIP in the station finder. U-Haul stores appear with the brand name in the row. On the map they are green refill markers.
