Shurflo Marine Oil Change Pump 8050-305-526 - 12V Self-Priming Diaphragm Transfer Pump, 1.5 GPM

The Shurflo Marine Oil Change Pump (part number 8050-305-526) is a self-priming 12V diaphragm pump built for winterizing, oil changes, and general fluid transfer aboard boats and RVs. Its self-priming design lifts fluid up to 7 feet (2.1 m) without manual priming, making it easy to draw oil, automatic transmission fluid, low viscosity gear lube, or anti-freeze solutions straight from a dipstick tube or reservoir into a waste container.

The pump runs on a 12 VDC motor drawing 4 amps and delivers a flow rate of 1.5 GPM (5.6 LPM) through a 3/8 inch FNPT port. It includes run-dry capability, so the motor is not damaged if it temporarily runs without fluid, and the motor is both ignition protected and thermally protected against overload, with a housing measuring 6.5 inches x 4.5 inches x 4.3 inches (165 x 114 x 108 mm). A hose kit is included for straightforward installation, and the unit is CE listed. This pump is a practical choice for boat owners handling routine engine oil changes, seasonal winterizing, or general low-viscosity liquid transfer tasks.
