Dry Sump Tank 5 Gal Single Scavenge

The Dry Sump Tank 5 Gal Single Scavenge by Peterson Fluid is an essential component for high-performance engine builders and serious automotive enthusiasts running modified or race-spec powerplants. This dedicated oil reservoir system separates the traditional wet-sump function into a standalone dry-sump configuration, allowing you to maintain superior oil control, reduce windage losses, and lower engine bay temperatures during sustained high-RPM operation. Whether you're building a street performance engine, track-focused vehicle, or competition platform, a quality dry-sump tank is non-negotiable for reliability and consistent oil pressure delivery under extreme conditions.

This single-scavenge unit features a 5-gallon capacity—ideal for mid-displacement engines up to approximately 500 cubic inches—with a robust construction designed to handle the demands of continuous circulation and positive scavenging. The single-scavenge configuration means one return line pulls oil from the engine sump back to the tank, while a dedicated feed system pressurizes clean reservoir oil back into the engine. The tank's internal baffles and settling chambers minimize aeration and foam generation, critical factors that degrade oil film strength and bearing protection during cornering and sustained throttle application. At 10.5 lbs, the compact footprint (13 x 12.75 x 25.2 inches) fits tight engine bay layouts while providing adequate volume to maintain stable pressure and temperature across multiple heat cycles.

This tank benefits engine builders running LSx, small-block Chevy, Ford Windsor, or other popular performance platforms where aftermarket dry-sump kits are standard. Installation requires coordination with a quality scavenge pump, pressure pump, and appropriate line routing to the engine block; most experienced mechanics or dedicated fabrication shops handle the integration seamlessly. The Peterson Fluid tank's proven design works with both street and racing applications, making it suitable for everything from weekend track days to full-season competition programs. Proper sizing—verified by displacement and operating RPM—ensures oil velocity and cooling efficiency remain optimized throughout the rev range.
