Elements and Performance Criteria

Work includes the maintenance of complex fuel systems used in the motorsport/performance enhancement environment. It includes the operation and function of complex fuel system components and systems, conduct of tests and interpretation of test results in order to analyse faults within complex fuel systems, determining repair and/or performance improvement strategies, conducting repairs, adjustments and post-repair checks
A complex fuel system is defined as a specialised motorsport/performance system incorporating a configurable management/control system and may include a duplicate/backup supply system and injection or multiple carburetion configurations
Fuel systems must cover sub-systems and components including fuel cells, pumps, pressure and/or flow regulation, management/control system and injection or multiple carburetion components
Diagnosis is to cover that for module and parts replacement in related electrical, electronic, pneumatic control systems
Fuel system faults covered by this unit include, but are not limited to, rough running, under/overfuelling, misfiring, poor performance, contamination and leakage
Fuel system faults covered by this unit must include indirect faults caused by the influence of external systems which may or may not be faulty in their primary operation

OH&S requirements include State/Territory and Commonwealth legislation, material safety management systems, controlling body requirements, manufacturer specifications and local safe operating procedures
Work is carried out in accordance with legislative obligations (including environmental requirements), health regulations, manual handling procedures and team insurance requirements
Work requires individuals to demonstrate analytical and organisational ability, judgement and problem-solving skills in the analysis and maintenance of complex fuel systems
Competence may be demonstrated in workplaces involved in the design, development, manufacture and maintenance of performance vehicles and/or performance vehicle components and assemblies used in motorsport

Tooling and equipment may include, but is not limited to, hand and power tooling, vacuum/pressure gauges, flow meters, exhaust analysers, multimeters, engine diagnostic computer hardware and software

Components may include, but is not limited to:
rollover valves
fuel cells
fuel lines
breathers
pickup pumps
main pumps
filters
fuel pots/surge tanks/collector tanks
pressure and temperature sensors
injectors
carburettors
hoses and fittings
refuelling equipment including churns/rigs, dry break valves, hoses and fittings

Personal protective equipment is to include that prescribed under manufacturer specifications, legislation, regulations and enterprise policies and practices

Controlling body rules, category rules and supplementary regulations
Team procedures relating to applying diagnosing and maintaining complex fuel systems
Task instructions including worksheets, checklists, plans, drawings and designs
Team procedures relating to reporting and communication
Team procedures relating to the use of tooling and equipment
Manufacturer/component supplier specifications and application procedures for test equipment and material
Australian Design Rules (where applicable)

Critical aspects of evidence
Interpret and apply team requirements, controlling body and category rules and supplementary regulations
Apply safety requirements including the isolation of equipment and the use of personal protective equipment

Follow task instructions, operating procedures and inspection processes to:

minimise the risk of injury to self or others
prevent damage to competition vehicle or equipment
achieve required outcomes within team time and quality standards
Correctly analyse, repair and conduct post-repair checks on a minimum of three (3) fuel system faults (on more than one fuel system type) and involve :

rough running, under/over fuelling, misfiring, poor performance, contamination or leaks, where:

at least one fault having possible combination causes involved in the sub-systems (fuel cells, pumps, pressure and/or flow regulation, management/control system and injection or multiple carburetion components)
the scope of the faults necessitates the use of a range of testing equipment
Work effectively with others
Modify activities to cater for variations in workplace context and environment

Underpinning knowledge

Diagnosis and testing procedures and test instrument application
Symptom and cause differentiation
Repair and/or performance improvement strategies
Removal, replacement and repair, adjustment and post-repair check procedures
Diagnosis theory including concept, design and planning
Record keeping procedures
Procedures for reporting equipment faults and component defects
Team guidelines regarding acceptable quality and tolerance levels
Equipment safety requirements
OH&S policies and procedures

Specific key competencies, underpinning and employability skills required to achieve the performance criteria
These include a number of processes that are learned throughout work and life, which are required in most jobs. Some of these are covered by the national key competencies, although others may be added. The details below highlight how these competencies are to be applied in the attainment of this unit.

Application of the key competencies in this unit are to satisfy the nominated level in which:

Level 1 - relates to working effectively within set conditions and processes;
Level 2 - relates to the management or facilitation of conditions or processes; and
Level 3 - relates to the design, development and evaluation of conditions or process.
How will the candidate apply the following key competency in this unit? The candidate will need to:

Collect, analyse and organise information
Collect, analyse, organise and understand information related to complex fuel system analysis and repair
(Level 2)

Communicate ideas and information
Communicate ideas and information to enable confirmation of work requirements, coordination of work with technical supervisors, other technicians and workers and reporting of work outcomes and problems
(Level 2)

Plan and organise activities
Plan and organise activities including the preparation and layout of the work area and obtaining equipment and material to avoid backtracking, workflow interruptions or wastage
(Level 2)

Work with others and in a team
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
(Level 2)

Use mathematical ideas and techniques
Use mathematical ideas and techniques to correctly interpret test results in order to determine required action for the maintenance of fuel systems
(Level 2)

Solve problems

Method of assessment
Assessment methods must confirm consistency of performance over time and in a range of workplace contexts
Assessment should be by direct observation of tasks and questioning on underpinning knowledge
Assessment should be conducted over time and may be in conjunction with assessment of other units of competence

Context of assessment
Assessment may occur on the job or in a workplace simulated facility with process equipment, material, work instructions and deadlines
