Aeromotive 66142 BoostWorx Auto-On Triple Fuel Pump PWM Controller Universal

Vehicle Fitment

• Universal - not vehicle-specific. Designed for stand-alone ECU applications running dual or triple Aeromotive 340 LPH in-tank fuel pumps (not OEM fuel pump modules)

Fitment Notes

• Requires a stand-alone ECU/ECM setup capable of closed-loop PWM pump control; not designed to integrate with a factory OEM fuel module
• Also specified by Aeromotive as the required controller for its Triple 450 LPH Trifekta Phantom Returnless in-tank fuel system, in addition to standard 340 LPH triple-pump builds
• Aftermarket pump hangers may need additional bypass fuel provisions to support closed-loop pump operation

Features

• Stand-alone, OE-type returnless fuel control system for dual or triple pump applications
• 1:1 manifold-referenced fuel pressure control via included stand-alone MAP sensor
• Auto-On staged pump activation - no relays or Hobbs switches needed
• Up to 2/3 reduction in power to the fuel pumps during idle and cruise vs. traditional systems
• Compatible with Aeromotive's line of 340 LPH in-tank fuel pumps
• Required controller for the Aeromotive Triple 450 Trifekta returnless system
• Over-temperature shutdown with automatic reset
• Short-circuit protection with automatic reset

Specifications

• Operating Voltage: 10-22V (compatible with voltage boosters)
• Continuous Power Rating: 80A minimum
• Controller Size: 4.5 in L x 3.5 in W x 2 in H
• Compatible Pumps: Aeromotive 340 LPH in-tank fuel pumps (dual or triple configuration)

Included Components

• 1x BoostWorx Auto-On Triple Fuel Pump PWM Controller
• 1x MAP Sensor and Mounting Hardware
• Wiring Harness with OEM-style Sealed Connectors

Product Description

The Aeromotive 66142 is a stand-alone PWM controller built for dual or triple fuel pump systems running on a stand-alone ECU, extending the same Auto-On staging logic found in Aeromotive's dual-pump controller to support higher-flow, multi-pump setups. It provides 1:1 manifold-referenced fuel pressure control through an included MAP sensor, staging additional pumps online automatically as boost demand increases.

This controller is also the required companion piece for Aeromotive's Triple 450 LPH Trifekta Phantom returnless in-tank fuel system, making it the go-to choice for extreme-horsepower builds running triple high-flow pumps in a single tank. As with other naked-pump controllers in this family, it's built around Aeromotive's own pump lineup rather than OEM fuel modules.

This kit suits high-horsepower, multi-pump builds on a stand-alone ECU - whether running three 340 LPH pumps or stepping up to the Trifekta's triple 450 LPH configuration - where OE-style returnless fuel delivery and automatic pump staging are needed without manual switches or relays.
