Peterson Fluid

<h3>Peterson Fluid Systems: Engineered for Racing, Built in the USA</h3><p>When professional racing teams need to protect a high-horsepower engine under the most punishing conditions imaginable, they turn to <strong>Peterson Fluid Systems</strong>. Founded and headquartered in Longmont, Colorado, Peterson has been a cornerstone of motorsport fluid management since 1976, earning the trust of competitors across NASCAR, NHRA, IHRA, SCCA, the World of Outlaws, the LeMans Series, and countless other sanctioning bodies worldwide.</p><p>Peterson's reputation is built on a simple but powerful philosophy: <em>Quality Without Compromise</em>. <a href="/1188-peterson-fluid">Peterson Fluid Systems</a> manufactures approximately 95% of its products in-house using state-of-the-art CNC machining, CAD/CAM design, and a full fabrication facility — ensuring every component meets the exacting tolerances that racing demands before it ever reaches a customer.</p><h3>Dry Sump &amp; Wet Sump Oil System Expertise</h3><p>At the heart of the Peterson catalog are its industry-leading wet and dry sump oiling systems. Peterson oil pumps feature billet aluminum construction, steel gerotor design, internal scavenge manifolds, and bolt-on fittings — delivering excellent flow with minimal parasitic drag. The brand's modular pump designs make them adaptable across a wide range of engine platforms and chassis configurations. Complementing the pumps, Peterson's hand-welded aluminum oil tanks incorporate internal baffling and sophisticated oil control designs that promote superior deaeration and consistent oil pressure, even under the lateral forces of road racing or the hard acceleration of drag racing.</p><p>Fluid management doesn't end at the sump. A properly sealed and serviced engine starts with reliable hardware at every junction, which is why Peterson's <a href="/1188-peterson-fluid-engine-oil-drain-plug-5560">engine oil drain plugs</a> are engineered to the same exacting standards as the rest of the lineup. These components are designed for secure, leak-free performance in demanding race environments where a single failure can end a race — or worse, an engine.</p><h3>Fuel System Components</h3><p>Peterson extends its fluid management expertise beyond oil with a comprehensive line of fuel system components. The brand's <a href="/1188-peterson-fluid-fuel-tank-6268">fuel tanks</a> — including purpose-built configurations for popular platforms — are constructed from aluminum with the same hand-welded craftsmanship that defines Peterson's oil tanks. Whether the application calls for a dry sump reservoir or a dedicated racing fuel cell, Peterson delivers a solution engineered for both safety and performance.</p><h3>Filtration &amp; Filter Adapter Solutions</h3><p>Protecting critical engine components requires more than just moving oil efficiently — it requires keeping that oil clean. Peterson's <a href="/1188-peterson-fluid-engine-oil-filter-adapter-kit-17844">engine oil filter adapter kits</a> are precision-machined from high-grade materials and designed to integrate seamlessly with Peterson filter mounts. Some Peterson primer filter mounts even allow pre-lubrication before engine startup, delivering oil pressure to vital surfaces before the first crank — a feature that can significantly extend engine life in a racing program. Oil and fuel filters from Peterson are tested before shipment and trusted extensively across the NASCAR, NHRA, and World of Outlaws paddocks.</p><h3>A Legacy of Racing Pedigree</h3><p>From sprint cars to endurance prototypes, Peterson Fluid Systems products have proven themselves on virtually every form of motorsport surface. Teams like Robert Yates Racing, Dale Earnhardt Inc., and Roush Racing have relied on Peterson's aluminum oil tanks, and the brand continues to innovate based on direct feedback from racers competing at the highest levels. Whether you are building a dedicated race car or a serious performance street machine, Peterson Fluid Systems offers the fluid management components to do the job right.</p>
