Application
This unit describes the performance outcomes required to install liquefied petroleum gas (LPG) fuel systems. It involves preparing for the task, selecting, installing, testing and adjusting the system for correct operation, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The LPG fuel systems include those of agricultural machinery, forklifts, heavy commercial vehicles, light vehicles or mobile plant machinery.
Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.

Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:
install one complete liquefied petroleum gas (LPG) fuel system in a vehicle.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to installing LPG fuel systems, including procedures for working with extremely cold and flammable gas
environmental requirements, including procedures for preventing loss of gas to atmosphere
requirements of AS/NZS 1425 LP Gas fuel systems for vehicle engines, including:
containers and container sub-assemblies
fuel service lines
fuel control equipment
Australian standard inspection, testing and commissioning requirements
LPG system adjustment procedures, including exhaust gas analysis
Australian standard certification, compliance plate, and marking and label requirements.
Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the LPG fuel systems that they have installed, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
AS/NZS 1425 LP Gas fuel systems for vehicle engines
manufacturer vehicle LPG system specifications
one vehicle requiring installation of an LPG fuel system
LPG installation kit, including the following components:
fill valve and fill hose
fuel container and mounting
service line
vaporiser
regulator
safety lock-off devices
mixers or injectors
associated electrical and electronic system, including selector and safety switches
compliance plates
testing equipment for LPG fuel systems, including exhaust gas analyser
tools, equipment and materials for installing LPG fuel systems.
