This adjustable wrench covers the full range of AN fitting sizes used across an EFI fuel system installation, from small sensor lines up to large supply and return lines, without the need for a full set of fixed-size wrenches.

Product Highlights:

• The adjustable jaw handles fitting sizes from -4AN to -16AN with a single tool.
• The jaw design grips the fitting flats securely without rounding them off or damaging the finish.
• A curved design option reaches fittings in tight engine bay locations that a straight wrench cannot access.
• This wrench is a practical addition to the tool kit for any EFI fuel system installation or service.
