OE Part Number:
This 4-12AN fuel line fittings installation and removal tool set is a universal professional automotive repair kit designed for most cars, trucks, and modified vehicles. It serves as an essential auxiliary tool for AN hose assembly, fuel line connection, and pipeline disassembly, perfectly solving difficult installation and removal problems encountered during fuel system modification and maintenance.
Basic Product Details Made of high-strength treated steel with anti-rust and anti-deformation treatment, this full tool set covers universal specifications from 4AN to 12AN, matching mainstream AN fuel hose and fitting sizes on the market. Equipped with an adjustable AN fitting hose wrench and multi-functional assembly and disassembly tools, the whole kit integrates clamping, positioning, installation and removal functions. Universally applicable to all automotive models with modified AN fuel lines, oil pipelines and vacuum pipelines, with no specific model and year restrictions.
Core Upgrade Advantages Different from single-function ordinary maintenance tools on the market, this integrated tool set combines all required tools for AN line maintenance in one package, avoiding the trouble of purchasing scattered tools separately. The upgraded steel structure features high hardness and strong toughness, not easy to slip or damage fittings during operation. The adjustable wrench design adapts to different AN specification pipelines, greatly improving construction efficiency. The humanized tool structure avoids scratching pipeline threads and fittings, effectively protecting modified fuel system parts. The overall lightweight design allows both professional repair shops and DIY enthusiasts to operate easily.
Solves Common Owner Pain Points Traditional manual assembly and disassembly of AN fuel lines often causes slippery hands, thread damage, fitting deformation and pipeline leakage due to uneven force. Many car owners and maintenance personnel face difficulties in tight-space pipeline operation, low installation efficiency, and secondary damage to new fittings during replacement. Unprofessional operation also leads to loose fuel line connections, resulting in fuel seepage and pipeline looseness after installation. This dedicated tool set effectively avoids all common construction errors and solves pipeline assembly and disassembly difficulties.
Compatible OBD / VCDS Fault Codes This professional fuel line tool set assists in repairing and eliminating hidden faults caused by improper pipeline assembly, including fuel system leakage, unstable fuel supply, and pipeline loose connection issues that trigger indirect engine operation anomalies.
Logistics & Shipping Benefits We provide free global shipping for all orders. All fuel line tool sets are in sufficient overseas inventory, with orders processed and shipped within 24 business hours after payment confirmation, supporting fast vehicle fuel system maintenance and modification work.
Warranty & Installation Support Every OUSIMY 4-12AN fuel line tool set enjoys a 2-year manufacturer warranty. The tool set comes with standardized operation logic, requiring no professional skills. It supports friendly DIY maintenance and modification, helping users complete fuel line assembly and disassembly work independently.
Full Fitment Vehicle List Universal fit for all cars, trucks, SUVs and modified vehicles with 4AN to 12AN fuel lines, oil lines and vacuum pipeline systems; No restriction on vehicle brand, model and production year
