FUEL DISTRIBUTION SYSTEM MECHANIC

Duties & Responsibilities: (1) Inspects and tests fuel receiving, storage, and distribution facilities and performs preventive maintenance on fuel systems and components. Inspects fuel tanks and vents for proper ventilation.

Checks interior and exterior of tanks for corrosion, leakage, contam ination, and sludge and correct operation of roof sumps, roof seals, liquid level gauges, product recovery systems, etc., and inspects gauging equipment for calibration. Performs corrosion control on exposed piping.

Performs ground resistance tests and pressure checks system to identify leaks. Checks pumps for unusual noise, vibration, and proper operation. Performs hydrostatic tests on hoses. Tests and calibrates fuel flow meters, and checks manual and diaphragm valves for proper operation.

Conducts diagnostic checks on sensors, alarm components, and emergency shutoffs. Inspects tank cleaning equipment such as portable pumps, respirators, air lines, harnesses, hoses, and compressors. Inspects entire fuel distribution system and components to detect possible explosive and toxic hazards and system deficiencies.

Conducts follow-up inspections of contractor and in-house repairs. Maintains records of inspections, maintenance, and repairs, as required. (2) Performs all phases of liquid fuel system and component maintenance including preventive maintenance, troubleshooting, repair, and modification.

Removes installs, repairs, and troubleshoots component parts of fuel systems to correct malfunctions of turbine, centrifugal, and rotary pumps, manually operated plug/ball valves, hydraulically­ operated diaphragm-type valves, pilot control systems, tank gauges and vents, filter separators, fuelflow meters, hydrant outlets, differential pressure gauges, and truck loading and fill connections.

Performs modification of systems in accordance with applicable manuals, technical publications, and manufacturer's specifications. Lubricates valves and pumps; replaces gaskets and seals; corrects pumping equipment misalignment; cleans strainers and filters; services filter separators; and checks meters for correct delivery and calibration.

Troubleshoots, overhauls, removes, and replaces high/low level controls, liquid level gauges, automatic fueling/defueling valves, pressure regulating valves, water drain valves, excess flow valves, pressure/vacuum vents, and roof seals and sumps. Cleans and purges equipment.

Disassembles units and examines component parts for evidence of scratches, wear, cracks, pits, or breaks. Troubleshoots, repairs, and tests equipment installed in vehicle gas stations and truck loading fill stands. Performs liquid calibration of fuel storage tanks and flow meters.

Measures, cuts, threads, joins, and fits piping as required to perform system modification or to repair/replace system components. (3) Troubleshoots and repairs problems in the electrical components of liquid fuel distribution systems. Performs electrical inspection of electro-mechanical components.

Uses multi-meter to check system continuity and identify minor system problems. Replaces burned out fuses. Diagnoses, repairs, and adjusts electrical components such as electrical controls, motors, and other devices using electrical measuring equipment (e.g., voltmeters, ammeters, and ohmmeters).

Examines motors, diagnoses defects, and makes on-site repairs when possible. Disconnects motors requiring major repair and transports to shop. Uses ohmmeter or megger instrument to test static ground throughout system. Adjusts, aligns, and calibrates gauges and meters to ensure maximum operating efficiency.

Installs and performs pressure tests for operation of new, repaired, and modified components, valves, and controls. Performs inspection, maintenance, and repairs on all controls, switches, and connecting and ground cables. (4) Participates in cleaning the interior surface of bulk storage tanks, above and below ground, by entering tanks.

Cleans interior surface and tests seams and other areas suspected of leakage. Performs corrosion control by removing corrosion and repainting surfaces. Removes and disposes of sludge. Follows safety precautions in tank entry, ventilation tasks, and in disposing of sludge.

(5) Utilizes safety practices and procedures following established safety rules and regulations and maintains a safe and clean work environment. Uses and assures proper fit of required safety equipment (i.e., foot, eye, breathing, and ear protective gear) and clothing (i.e., cotton).

Polices grounds, buildings, and pits to maintain area in accordance with fire prevention and security directives. (6) Performs other as duties as assigned.
