Oil tank fill & vent piping guide: this heating oil piping article gives advice and example photos for the installation, inspection, & leak troubleshooting of oil tank fill & vent piping for both buried and above ground oil storage tanks .

See our complete list of heating oil piping topics beginning at OIL TANK PIPING & PIPING DEFECTS. Also see additional visibly detectable oil tank defects listed at ABOVE GROUND OIL TANK (AST) GUIDE and Heating Oil Piping. Sketch provided courtesy of Carson Dunlop Associates.
Here are a some important indicators of tank condition that any home owner or home inspector can examine when an oil storage tank is visible and accessible inside or at a building.
The oil company recommends going to 2", and most new installations use a two-inch diameter vent pipe; we've seen vent piping as small as one inch on oil tanks. During fill fuel is delivered at an average rate of 60 or even 70 gallons per minute.
Improper or blocked oil tank air exit venting can place excessive stress on tank seams and piping. See OIL TANK PRESSURE for a detailed explanation.
Fill and Vent Piping for Duplex Heating Oil Storage Tanks
At buildings where two heating oil storage tanks are installed, typically indoors, this Audel Oil Burner Guide sketch shows the proper arrangement of fill piping, vent piping, and oil line piping leaving the tanks.
We have seen an alternative arrangement that provides a fill line only to the first tank, with the second tank filled by a second pipe exiting the top of the first oil tank - not an arrangement we recommend as this forces the first oil tank to be fully pressurized at the oil delivery truck pressure during fill-up of the second tank.
The piping shown in this Audel sketch is better. Details about piping of fill and vent and oil supply lines for duplex oil tanks are at DUAL OIL TANKS - PIPING.
