With higher fuel prices affecting
tank system owners and managers, employing
the best in-tank inspection methods becomes
increasingly important. OpticSweep provides
the inside information that tank owners need
through the unprecedented use of fiber-optic
technology.
"This pertains
to all storage systems, both underground and
aboveground, constructed of any material and
storing nearly any product - gasoline, diesel,
residential and commercial heating oils, aviation
jet fuel and others."
"Pump out
tank bottoms. If water is left in
the tank bottom, phase separation can occur
when the ethanol blend enters the service-station
tank. With phase separation, an ethanol-water
solution settles to the tank bottom. Depending
on the amount of water present and the
location of the pump suction near the tank
bottom, the ethanol-water solution may
or may not be delivered to the customer. An
engine will not run properly if this solution
flows into a vehicle's tank. Because
the ethanol separates to the bottom of
the tank, the octane level of the fuel
is reduced and some of the front-end volatility
is reduced-- thereby causing problems for
the engine."

"The
primary tank should be inspected monthly
for the presents of water. Inspections
should take place at the lowest possible
points inside the primary tank. Remove
any water found. Water and sediment
in fuel can cause plugging of filters, also
bacterial growth originating from the fuel
can cause filters to plug and corrosion of
the tanks and lines"
