Item number: MQ-06-05

Modern vehicles commonly use the SAE J2044 standard for quick connect fittings in applications such as air breather lines, vacuum lines, PCV lines, coolant lines, and Electronic Fuel Injection (EFI) fuel lines.

These fittings allow you to adapt the OEM style J2044 female quick-connect fittings to AN lines.

Fuel systems commonly use the 5/16" or 3/8" size quick connect fittings. Most GM vehicles use M10 (9.89mm) quick release fittings for PCV breather lines. Ford and Dodge commonly use the 5/8" (15.82mm) quick release fittings for PCV breather lines. Measure your fittings to confirm the exact size needed.
