Product Description
Product Details
1. Copper Washer / Restrictor
Seals connection points between fuel line and carburetor or crankcase. Restrictor models feature a precision 0.5–1.5mm orifice to control return fuel flow and maintain stable oil pressure.
2. Hollow Bolt for Fuel Passage
A hollow bolt with side inlet holes allows fuel to flow through the center while securing the fuel line fitting. Typically requires two copper washers (top and bottom) for proper sealing.
3. Copper Tube for Rigid Routing
Hard copper tubing (4–6mm OD) routes fuel or pulse pressure in areas where rubber hoses cannot fit, providing durable, heat-resistant fuel transfer.

FAQ
Q1: How do I identify which copper component I need?
A: Remove the old part and measure its dimensions. Match the outer diameter, inner diameter, thread size, or orifice size to the specifications above.
Q2: What is the recommended installation torque?
A: For copper washers and hollow bolts, use 8–12 N·m (6–9 ft-lbs). Over-tightening may crush the washer excessively and cause sealing failure.
Q3: Can I clean a clogged restrictor instead of replacing it?
A: Yes. Use a fine wire to clear the orifice (0.5–1.5mm), then flush with carburetor cleaner. Do not enlarge the hole, as this will alter fuel pressure regulation.
