We can predict how long a fuel tank is expected to last out in the sun, but the deterioration process is accelerated considerably when water is involved.

2. In a country like Australia with such harsh conditions,
keeping anything outside for extended periods of time
poses unique challenges.
So how can we prevent fuel tanks from the corrosive
effects of the elements?
3. Diesel fuelcontainers are, essentially, large cylinders or boxes
made of stainless steel and iron. They range in size from
small-scale self-bunded storage tanks to massive installations
designed for supplying fuel to thousands of vehicles and
machines each load.
A LEAKY PROBLEM
4. We can predict how long a fuel tank is expected to last out
in the sun, but the deterioration process is accelerated
considerably when water is involved.
If a pool of water lies stagnant against the surface of a
tank, any chips or exposed areas of the container can rust
quickly and go brittle.
5. One method that has come into favour recently involves
attaching a flat piece of metal to the underside of the fuel
tank. This acts as a weather strip, and keeps water moving
away from the base of the tank.
Initial versions of this weather strip used an epoxy resin to
work as a glue, but the effects of extreme heat struck
once more and weakened the adhesive.
6. A new fixing method, which involved arc welding the weather
strip to the base, was invented and is now in use internationally.
Its estimated that using these weather strips will extend the life
of a regular fuel supply by years.
7. Routine inspections of fuel tanks are also an option and
have proven themselves to be a cost-effective method of
extending their lifespan.
While it involves sending someone out to manually
inspect the tank it is still better than unexpectedly losing
a tank for days or even weeks while a replacement is
delivered, much less the environmental and financial
cost of wasted fuel.
