Part A · Multiple choice
Before removing any underground lid, you should first:

- C) Start a vehicle nearby for light
- D) Remove all the lids at once
A drop tube should be made of:

- B) Aluminum or other non-magnetic, fuel-compatible metal
- C) Copper only
- D) Rubber
Finding fuel (product) in a sump means:
- A) It's normal after rain
- B) Something is leaking — it's a safety finding to document and escalate
- C) Nothing to worry about
- D) The sensor is wrong
Stage II vapor recovery captures vapors:
- A) During delivery, back to the truck
- B) During dispensing, from the vehicle back to the underground tank
- C) From the vent pipe only
- D) It doesn't capture vapor
During tank water removal, you stop pumping when:

- B) You start pulling fuel instead of water
- C) After five minutes
- D) The ATG clears
Variable-speed FE Petro STPs are controlled by:
- A) A contactor and capacitor
- B) A MagVFC (variable frequency controller)
- C) The ATG
- D) A drop tube
Part B · True / False
Water in a spill bucket or sump may be drained onto the ground or into a storm drain if it's "just water."
True False
The overfill prevention valve typically restricts/stops fuel flow at about 90–95% of tank capacity.
True False
The MagVFC can be opened safely the instant power is disconnected.
True False
Unsealed conduit entries are a common water path into sumps.
True False
Part C · Short answer
Name three ways water gets into a tank.

Show answer key
- B — Check for vapor/odor and keep ignition sources away before opening.
- B — Aluminum or other non-magnetic, fuel-compatible metal — never PVC.
- B — Fuel in a sump is a safety finding; something is leaking. Document and escalate.
- B — Stage II captures vapors at the nozzle during dispensing and returns them to the tank (Stage I is during delivery, back to the truck).
- B — Stop when you start pulling fuel instead of water.
- B — A MagVFC controls variable-speed FE Petro STPs (fixed-speed uses a contactor + capacitor).
- False — Pump it out and dispose properly; even "just water" may carry a fuel sheen.
- True — Usually about 90–95% capacity.
- False — Wait one full minute after the LED display goes blank; the capacitor bank stores lethal voltage.
- True — Unsealed conduit is the #1 water path into sumps.
- Any three: delivery (water in the supply); leaking spill bucket / damaged fill cap; condensation; containment failure (compromised fittings/seals).
- Any three: ATG high water alarm; ATG water level reading; manual stick with water-finding paste; customer complaints.
- The fill adapter must come out first; note the drop tube's position/orientation so it goes back the same way.
- A containment basin around the fill pipe that catches fuel drips when the delivery hose is disconnected, keeping product out of the ground.
