Plumbing Requirements Site Preparation
Fuel Tanks
Follow tank manufacturer instructions, national, state, and local regulations for storage tank
installation.
On pumps (self-contained units), it is recommended that a vertical lift of 10-feet must not be
exceeded. The EPA and API regulates the vapor pressure of gasoline. A lift greater than
10-feet may result in vapor suction rather than gasoline suction.
Notes: 1) The maximum lift is defined as the vertical distance from the bottom of the suction
pipe in the storage tank to the pump shaft centerline of the pumping device.
2) Install vacuum actuated valve with shear section (per NFPA 30A) directly beneath a
self-contained pump when aboveground storage tanks are used. Without vacuum
actuated valve, sump may overflow. For more information, refer to manufacturer’s
installation instructions, Gasboy Product Service Bulletin 26-91, and
“Check
Valves” on page 31 .
Tanks that contain DEF can be aboveground or underground depending on the ambient
temperature of the geographical area in which the tanks are located. It is not recommended to
use aboveground tanks that contain DEF where temperatures may reach lows of 10
° F.
Leak Detectors
Use only listed leak detectors. Follow manufacturer instructions for leak detector installation.
STPs
Use only listed STPs. Follow manufacturer instructions for installation of STPs.
Pipe Installation
Use of incompatible materials or components with alternative fuels such as E85 can result
in leaks or unexpected failures of components resulting in fire or explosion or environmental
damage.
When dispensing alternative fuels such as E85, verify with the manufacturer if the material
of all plumping components are compatible with fuels such as E85 being dispensed.
