Barfield 101-00425 - Fuel Quantity Adapter Cable Bell 205A

The Barfield 101-00425 is a fuel quantity adapter cable designed to interface AC capacitance-based Fuel Quantity Indicating Systems (FQIS) on Bell helicopter platforms with Barfield fuel quantity test sets. Compatible with all serial numbers of the Bell 205A-1, Bell 205A, Bell 204A, Bell UH-1 Iroquois, and Bell AH-1 Cobra, it is one of the most broadly applicable Bell helicopter adapter cables in the Barfield product line.

Test Set Compatibility

The 101-00425 provides the aircraft-specific interface required between the helicopter's fuel system and four Barfield AC fuel quantity test sets: the DFQ40K, AC2K, 2548H, and 8000 series. Without the correct adapter cable, accurate testing, troubleshooting, and calibration of the aircraft's FQIS cannot be completed. This cable connects to the tank unit, compensator, and fuel quantity indicator circuits — enabling the full suite of capacitance measurement and indicator drive current tests supported by these test sets.

Key Features

• Compatible with all serial numbers of Bell 205A-1, 205A, 204A, UH-1 Iroquois, and AH-1 Cobra
• Works with Barfield DFQ40K, AC2K, 2548H, and 8000 series fuel quantity test sets
• Supports AC capacitance-based FQIS testing and calibration
• Manufactured by Barfield Inc. with rigorous quality assurance and calibration procedures
• Backed by the standard Barfield manufacturer's warranty

Applications

The Barfield 101-00425 is an essential tool for MRO facilities, military maintenance contractors, FBOs, and field service teams supporting Bell helicopter fleets. It supports recurring airworthiness inspections, troubleshooting of FQIS discrepancies, and indicator calibration in accordance with applicable maintenance manuals. For technicians performing fuel quantity system maintenance on UH-1 or 205A-series aircraft — whether in commercial, military, or government aviation environments — this adapter cable ensures proper test set connectivity for accurate, reliable results.
