Product Description

The Snow Performance SNF-52599R Triple Pump Race fuel hat is the highest-output fixed-configuration fuel hat in the SNF-52599 lineup, designed for 1999-2004 non-Cobra Ford Mustangs pushing serious power on the track. It houses three matched 470 LPH Hellcat 525 TI Automotive (Walbro) pumps inside a CNC-machined 6061 billet aluminum manifold, eliminating the T-fittings, rubber lines, and hose clamps of traditional multi-pump setups. Viton O-rings seal each pump leak-free, and a shared 10-micron prefilter feeds all three pumps simultaneously to prevent fuel starvation under hard acceleration or cornering.

Unlike the streetable configurations, the Race version runs all three 470 LPH pumps simultaneously at all times, delivering up to 1,600+ rwhp on E85 and 2,100+ rwhp on gasoline. This makes it the go-to choice for dedicated race builds where maximum fuel volume takes priority over current draw or heat management. Compatible with the Snow Performance Multi-Pump Relay Module (SNF-20003) for controlled activation, and pairs with the optional boost-activated pressure switch (SNO-81014) for staged pump management if desired.
