How to use Fuel Hauler Pro
What Fuel Hauler Pro does
Fuel Hauler Pro is a free phone tool for fuel haulers and tanker drivers. It turns a stick reading into gallons, shows how much room is left in an underground tank, predicts where the stick will land after you unload, and warns you before a drop could overfill the tank or put your truck over its weight limit.
It runs in your phone's browser, so there is nothing to install from an app store. You can add it to your home screen from the browser menu so it opens like a normal app. The calculators work without an account. Signing in only matters if you want your stations, tanks and drop history saved across phones.
Stick a tank and turn inches into gallons
Open Check a tank on the home screen and choose Stick only. Pick the tank size. The common sizes are listed as buttons, and Other size lets you pick any of the 79 standard tanks or type the tank's inside diameter and length yourself.
If the size comes in more than one width, choose the one that matches the tank under the fill. Fiberglass tanks usually have rounded ends and steel tanks usually have flat ends. The width matters: two 8,000 gallon tanks with different diameters can hold very different amounts at the same stick reading.
Type your stick reading in inches, or tap Read the stick from a photo and confirm the number it finds. The app shows the gallons in the tank, how full it is, and the room left to 90%. A tank is round, so each inch near the middle holds far more fuel than an inch near the bottom or top. That is why the app uses a tank chart instead of a straight line.
Every result shows a Chart source label. Generic estimate means it is using a standard shape for that size. Custom dimensions means it uses the diameter and length you typed. Maker chart means it is using the station's own chart saved on that tank. For the best numbers, save the station's posted chart on the tank in My stations.
The Tank chart screen lists the full chart for the tank you picked, line by line, with the 90% and 95% lines marked. You can print it for your binder.
Plan a drop so you don't overfill
Ullage is the empty space left in the tank. Most carriers and stations want the tank no more than 90% full after a delivery, and many overfill valves shut off at 95%. The safe amount to drop is the room up to 90%, not the room to the very top.
Open Plan a drop, type the stick before you unload and the gallons you plan to drop. The app shows the stick after the drop, the gallons in the tank after, and how full it will be. The top label stays green below 90%. It turns to a stop warning at 90%, a stronger warning past 95%, and a full red spill-risk warning if the drop will not fit at all.
If a drop is too big, tap Use max safe drop and the gallons are cut back to what fits under 90%. If you load from a saved station tank, the app also checks that the product you're carrying matches the product saved for that tank and shows a red WRONG PRODUCT warning if it doesn't.
When you scan the console printout, the app starts from the console's own gallons and shows any water reading. Water above zero is shown in amber, and water at or above your limit in Account is shown in red. Check for water before you drop.
Scan a BOL and verify a load
Tap Scan BOL on Plan a drop and take a photo of the bill of lading, or pick one from your photos. The app reads the products and gallons and offers to fill them in. Photos are read by an AI service and can be wrong, so check every number against the paper before you use it.
Quick-verify a drop, in the More menu, is a fast check after you unload: type the starting stick, the metered gallons and the tank diameter, and it shows where the stick should be. If your real stick is far off, look again before you leave. The tank size may be wrong, the meter may be off, or product may have gone into the wrong tank.
Load the truck helps split an order into your trailer's pockets and checks the gross weight against your limit. It warns you as soon as the load goes over, and can trim gallons to fit.
Tips for underground storage tanks
Stick slowly and straight down until the stick touches bottom, then read the wet line right away. Use water-finding paste on the bottom of the stick if you need a water reading.
Check the tank number and product at the fill cap and the color code before you connect. Compare your stick with the station's console reading. A big difference can mean a bad probe, the wrong tank, or a size you've picked wrong in the app.
If you don't know the tank, Look up this store's tanks searches the EPA's public tank records for size and in-service status nearby. Treat it as a hint. Records can be old or incomplete, and they don't list the tank's exact shape.
Deep tanks can be taller than a 10 foot stick. The app warns you when the tank you picked is deeper than that.
Safety reminders
Fuel Hauler Pro gives estimates, not certified readings. Always follow your company's procedures, the station's posted tank charts, the console and your own stick. If anything doesn't add up, stop and check before you drop.
Never rely on a photo reading, an EPA record or a generic chart to override what you see at the tank. When in doubt, drop less and stick again.
