Connecticut (CT) P-8 Journeyperson Gasoline Tank,
Piping, and Pump Exam | Latest Verified Questions and
Detailed Answers
OVERVIEW DESCRIPTION:
This Comprehensive set of multiple choice questions is designed for the CT P-8
Journeyperson Gasoline Tank, Piping, and Pump Exam, a closed-book, computer-based test
that evaluates the knowledge and skills required to install, repair, and maintain petroleum
storage tanks and associated pumping equipment. The exam is administered by an
approved testing vendor on behalf of the Connecticut Department of Consumer Protection
(DCP) and covers essential topics such as aboveground and underground tank installation,
piping and tubing selection, pump and dispenser systems, leak detection and containment,
as well as critical code compliance with the International Fuel Gas Code, International Fire
Code, NFPA 30, and applicable OSHA workplace safety standards.
QUESTION 1

flammable liquid must be located from the nearest important building on the same
property, according to NFPA 30?
A) 5 feet
B) 10 feet
C) 25 feet
D) 50 feet
CORRECT ANSWER: D
EXPERT RATIONALE: NFPA 30 Table 22.4.1.1(a) requires a minimum 50-ft separation
between a protected aboveground tank storing Class I liquid and an important building.
QUESTION 2

of a single underground storage tank (UST) for motor fuel at a retail service station?
A) 10,000 gallons
B) 20,000 gallons
C) 30,000 gallons
D) 40,000 gallons
CORRECT ANSWER: D
EXPERT RATIONALE: IFC Section 5706.2.2 limits individual USTs at motor fuel-dispensing
facilities to 40,000 gallons each.
QUESTION 3
When installing underground steel tank piping, which of the following provides the
required corrosion protection?
A) Asphaltic coating only
B) Cathodic protection in conjunction with a dielectric coating
C) Wrapping with polyethylene tape without impressed current
D) Galvanizing all threaded joints
CORRECT ANSWER: B
EXPERT RATIONALE: Steel UST piping must have a corrosion-resistant coating and
cathodic protection to meet 40 CFR 280.20 and NFPA 30 requirements.
QUESTION 4
A submersible turbine pump (STP) at a motor fuel dispenser must be equipped with an
emergency shutoff device that stops fuel flow if a collision occurs. This device is
commonly known as a(n):
A) Check valve
B) Solenoid valve
C) Impact (shear) valve
,3|Page
D) Pressure relief valve
CORRECT ANSWER: C
EXPERT RATIONALE: IFC Section 2306.8 requires an impact valve (shear valve) at the
dispenser base to shut off fuel if the dispenser is knocked over or displaced.
QUESTION 5
Which code regulates the installation of gas piping for fuel gas systems in Connecticut?
A) NFPA 54
B) International Fuel Gas Code (IFGC)
C) NFPA 30A
D) ASME B31.3
CORRECT ANSWER: B
EXPERT RATIONALE: Connecticut adopts the International Fuel Gas Code (IFGC) for fuel
gas piping; IFGC applies to natural gas and LP-gas piping systems within buildings.
QUESTION 6
What is the minimum thickness of concrete required for the secondary containment dike
floor around an aboveground storage tank storing gasoline?
A) 2 inches
B) 3 inches
C) 4 inches
D) 6 inches
CORRECT ANSWER: C
EXPERT RATIONALE: NFPA 30 Section 22.11.2 requires dike floors to be of impermeable
material with a minimum thickness of 4 inches of concrete to prevent leakage.

QUESTION 7
For a new motor fuel dispenser installation using a suction pumping system, the
maximum vertical lift from the tank to the dispenser must not exceed:
A) 10 feet
B) 12 feet
C) 15 feet
D) 20 feet
CORRECT ANSWER: B
EXPERT RATIONALE: Suction pumping systems are limited by atmospheric pressure;
industry standard limits lift to about 12 feet to avoid cavitation and ensure reliable fuel
delivery.
QUESTION 8
When installing flexible metallic piping for underground fuel lines, what is the primary
requirement regarding joints?
A) All joints must be threaded and sealed with Teflon tape
B) Joints must be welded and hydrostatically tested
C) Only factory-made transition fittings may be used
D) Mechanical joints must be accessible for inspection
CORRECT ANSWER: D
EXPERT RATIONALE: NFPA 30 and UST regulations require that all mechanical joints on
underground piping be accessible, typically through manways or sumps, for leak
monitoring and repair.
QUESTION 9
Which of the following overfill prevention methods is acceptable for an underground
storage tank receiving motor fuel?
