This is a Pryco, Inc. PY300ULDW — a UL-Listed, Double-Wall day tank (or sub-base fuel tank) control panel for a 300-gallon diesel fuel tank, the kind used to feed emergency generators or boiler systems. The panel shows pump run/test status, a high-fuel-level light, and a rupture alarm (for the double-wall containment, in case the inner tank leaks into the outer wall).

• Main storage tank — your 300-gallon Pryco tank — holds the diesel reserve.
• Day tank — a smaller tank mounted near the generator that a transfer pump keeps topped off from the main tank, so the generator always has fuel right at hand.
• Overflow-return tank (this panel) — a safety catch basin. If the day tank overfills, oil flows from its overflow line into the inlet port of this overflow-return tank. A float switch and pump then send that fuel back to the main storage system rather than letting it spill.

The panel's lights map directly to that job:

• Day Tank Leak — signals fuel arriving here from the day tank's overflow line
• Pump Start / Pump Running — the overflow-return pump kicks in to move the collected fuel back out Hurtado
• Tank Empty / Operating Range / High Level Alarm — track the fuel level inside this catch tank itself, and if it keeps rising even after the pump runs, the High Level Alarm fires as a warning that something's wrong upstream Simplexdirect
• Push to Reset — clears the alarm once the issue's addressed
