Show original supplier description

The Precision Raceworks F-Series (F3x/F2x) B58 High Performance Fuel Pump is engineered for demanding applications, including daily driving and racing, supporting all blends of E85 fuel. It comes completely assembled and ready for installation, eliminating the need for core charges. The package includes the pump itself, a fuel filter, performance fuel lines, and the sending unit, meaning no additional components are required for a complete setup. Available in different stages, the Stage 3 offers up to 900whp support (850whp on 100% E85), while Stage 4 supports up to 1,000whp (950whp on 100% E85). The Stage 4.5, utilizing a Walbro 525 pump, supports over 1,000whp on 100% E85. All stages are designed as true plug-and-play solutions, requiring no cutting or splicing of wires, and can be installed in a home garage. The Stage 4 and 4.5 kits include upgraded AN-6 fuel feed lines with a fuel pressure regulator and return lines, a new in-line fuel filter, and a 13psi boost reference switch (hobbs switch).

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
