Product Description

The Snow Performance SNF-52599H is a triple pump, streetable fuel hat designed as a direct drop-in replacement for 1999-2004 non-Cobra Ford Mustangs. Built from CNC-machined 6061 billet aluminum with a black anodized finish, it eliminates the hose clamps, T-fittings, and rubber lines of traditional multi-pump setups in favor of a clean, leak-free integrated manifold. Genuine TI Automotive (Walbro) pumps are secured with Viton O-rings, and a shared 10-micron prefilter feeds all three pumps simultaneously to prevent fuel starvation under hard driving conditions.

The streetable triple-pump configuration pairs one 450 LPH base pump with two 470 LPH high-flow pumps, allowing the smaller pump to handle everyday street use while the additional pumps stage in on demand via a boost-activated switch. This setup draws 10-12% less current than the full Race configuration, making it the preferred choice for street/strip builds targeting 1,500+ rwhp on E85 or up to 2,000+ rwhp on gasoline. Compatible with the Snow Performance Multi-Pump Relay Module (SNF-20003) and boost pressure switch (SNO-81014) for seamless pump staging.
