Important Considerations when Changing Fuel Types Installation
• Biodiesel fuels must conform to American Society for Testing and Materials (ASTM)
standards for biodiesel fuels. Mixes of diesel with cooking oils, other plant or animal
derived oils, and so on, are not considered biodiesel. Use of such mixes may void warranty
on the hydraulic components of the unit.
• Review the latest copy of the unit’s warranty statement regarding the use of fuel.
• Certain fuels (especially fuels enhanced with alcohol) when first used in tanks previously
containing a different fuel may clean out the tanks and force a large amount of
contaminant into the dispenser. Other than abnormally clogging filters, this large quantity
of contaminant may damage certain dispenser components. Do not run units without
filters at such times. It is normally required that tanks and lines be cleaned of all water,
sediment, and contaminant before such conversions to minimize potential

pump/dispenser downtime or damage. Damage to hydraulic components from
contamination when not using filters is not covered by warranty. For recommendations,
consult your ASC or Gasboy distributor.
• Do not use any equipment that was formerly used to store or dispense any other fuel or
liquid with DEF. Dispensers designed for use with DEF must only be used with DEF.
• Do not use prover cans meant for engine fuel with DEF or vice versa.
• Although conversions from one fuel to an equivalent fuel (say from another supplier)
generally do not create issues, it is recommended that after making any fuel type
conversions (including those to alternative fuels such as E85 or back), all units be visually
inspected for leaks, two days, one week, and one month after fuel conversion. Have your
ASC repair any leaks found. This must also be performed for standard fuels when
significant new additives are incorporated.
The above guideline does not apply to flexible fuel model dispensers.
IMPORTANT INFORMATION
• Whenever non-equivalent fuel conversions are performed, it is recommended that all units
be checked for calibration within one month of fuel conversion.
• Some non-equivalent fuel conversions will necessitate the requirement to change the

pump/dispenser filter type previously used. For any changes required, consult your ASC
or Gasboy distributor.
• In flexible fuel dispensers, Gasboy recommends the use of 10 micron filters for

gasoline-based flexible fuels. Although the use of finer filtration is allowable, filters will
tend to clog prematurely, causing excessive filter maintenance cost.
• Use only meters and registration devices for DEF that have a National Type Evaluation
Program (NTEP) Certificate of Compliance issued by the National Conference on Weights
and Measures (NCWM).
• Non-metallic piping and components used in aboveground DEF service must have high
melting points and adequate strength and durability. Some plastic compounds that are
suitable for DEF may not be compatible with petroleum products. They must be avoided
at locations where they can come in contact with petroleum from a routine operation or a
spill.
• An anti-siphon valve must be installed on AST where the DEF level can be at a higher
elevation than the supply piping or the dispenser. The valve will prevent a potential leak in
the piping from creating a siphon that can cause a product release.
