Mustang Vortech Fuel Management Unit Recalibration Kit 4:1
Part Number: 6Z170-015
Vortech 4:1 Fuel Management Unit Recalibration Kit.
The Vortech Standard Fuel Management Unit (FMU) is designed for use on multi-point electronic fuel injected engines. It is a secondary fuel regulator that installs in series with a stock regulator on the return line to the tank. The unit increases fuel pressure in proportion to boost pressure (this assumes the pump being utilized is of sufficient pressure and flow to deliver the fuel required).
All Vortech FMU's feature CNC machined, 6061-T6 aluminum construction and a blue anodized finish. Vortech FMU Recalibration Kits include a new ring, washer and fluorosilicone diaphragm. The 4:1 unit was designed for high-output applications and can be used with 38 or 42 lb/hr injectors.
