Precision Raceworks X3 / X4 (F25 / F26) High Performance Low Pressure Fuel Pump

OVERVIEW

The F25 X3 and F26 X4 share their engines with the F3X cars but use their own fuel tank and pump bucket, so the standard F-Series pump does not fit. The factory pump is sized for stock power and is not rated for 100% E85.

The Precision Raceworks X3 / X4 (F25 / F26) High Performance Low Pressure Fuel Pump is a drop-in replacement: a new OEM-style bucket assembly with a Walbro pump pre-installed, a new sending unit and new filters. Stage 2 uses a Walbro 450 for builds to 575 whp, and Stage 2.5v2 uses a Walbro 535 for 675 whp. There are no wires to cut or splice, nothing to assemble and no core charge.
