Snow 2019+ GM Half Ton High Output Fuel Hat

Are you tired of multi-pump fuel upgrades that require a bunch of T-fittings, unreliable hoses and hose clamps? Snow Performance has the solution! The Snow Performance Multi-Pump Fuel Hats feature a billet aluminum manifold with CNC machined passages making these the nicest high output fuel pump upgrade on the market! This design eliminates the need for hose clamps and rubber or plastic lines that can deteriorate and cause problems. No detail has been overlooked with these assemblies. The CNC machined bodies hold the fuel pumps securely and feature Viton chemical-resistant O-rings and guarantee a perfect leak-free fit. Snow Performance Fuel Hats are engineered, CNC machined, and built in the USA from 6061 billet aluminum. These billet hats receive a black anodized finish for the ultimate durability and corrosion resistance, making them compatible with E85 and other harsh fuels. Snow fuel hats completely replace your factory fuel hat/bucket for an easy installation, retaining your factory tank features including, the OE fuel level sending unit, EVAP system, filler neck, and if equipped with saddle style tanks, the fuel transfer pump functionality. Snow fuel hats feature female 10AN ORB feed and 8AN ORB return ports. 90 degree swivel adapter fittings are sold separately to adapt to your desired combination of 10AN, 8AN or 6AN lines. To meet your specific vehicle's fuel demands, these pump assemblies are configurable with a combination of 2 or 3 fuel pumps. No knock-off pumps here. Get OE reliability with genuine TI Automotive (Walbro) fuel pumps in your choice of flow rates (450LPH or 470LPH). These fuel pumps are designed for a return-style installation only. Do not attempt to run these pumps in a returnless application. These pumps are compatible with 100% Gasoline, 100% Ethanol or any blend of Gasoline and Ethanol (E10, E85, E98 for example).

Highlights

• Does NOT include Fuel Level Sending Unit. Does NOT Include Fittings.
• Includes Wiring Harnesses for pumps and fuel level sending unit.

Fitment Notes

These pumps are NOT compatible with methanol. For street-driven applications, it can be beneficial to combine a smaller fuel pump along with one or two larger fuel pumps. This allows you to street drive on the smaller fuel pump which has a lower amp draw and does not generate as much heat. Once you get into boost, the larger pumps can be activated to support your high horsepower needs. The easiest way to do this is to use a Snow Performance Boost activated pressure switch (part # SNO-81014) and a Snow Performance Multi-Pump Relay Module (part # SNF-20003). Available pump configurations are shown below: 2 Pump Street able Configuration (one 450lph pump and one 470lph pump). This configuration is capable of supporting 1000+ rwhp on e85 and 1300+ on gasoline. -Current Selection 3 Pump Street able Configuration (One 450lph pump and Two 470lph pumps)- This configuration is capable of supporting 1500+ rwhp on e85 and up to 2000 rwhp on gasoline. This configuration draws 10-12% less current than the Race 3 pump version. 3 Pump Race Configuration (Three 470lph pumps). This configuration is capable of supporting 1600+ rwhp on e85 and up to 2100 rwhp on gasoline. This configuration is designed for max effort/flow.

Notes

• 3 Pump Xtreme Configuration (Three 490lph 535 pumps). This configuration can support 1900+ on E85 and up to 2500 rwhp on gasoline. This configuration is designed for max/effort/flow. (All 3 pumps MUST run at the same time! If all 3 pumps are not running at the same time, you will see pressure issues because it will backfeed through the remaining unpowered pump (s). If you are looking to stage your pumps, this Xtreme configuration will not work. You will need to run our 3 Pump Race, 3 Pump Street, or 2 Pump Street.)
• 3 Pump Street Able Configuration (One 450lph pump and Two 470lph pumps)- This configuration is capable of supporting 1500+ rwhp on E85 and up to 2000 rwhp on gasoline. This configuration draws 10-12% less current than the 3 Pump Race version.
• 2 Pump Street able Configuration (one 450lph pump and one 470lph pump). This configuration can support 1000+ rwhp on E85 and 1300+ on gasoline.
