AC PERFORMANCE 24-piece Assorted Fuel Line Quick Connector Kit — SAE-to-8mm Adapters with FKM O-rings, 90° & Straight

AC PERFORMANCE 24-piece assorted fuel line quick connector kit provides multiple SAE-to-metric fittings for fast, leak-resistant connections across common fuel and fluid lines.

This compact kit groups 24 connectors in 90° elbows, straight couplers, and pipe fittings sized to adapt SAE hose diameters (5/16" 7.89mm, 3/8" 9.49mm, 9.89mm) to 8mm lines. Built from fuel-compatible materials with FKM O-rings, the set addresses repair, retrofit, and prototype needs for automotive, marine, and small-engine fuel systems where reliable sealing and mixed-diameter transitions are required.

How does this kit fit different fuel line sizes?

The assortment includes matched pairs of 90-degree, straight, and pipe-style connectors that convert popular SAE diameters to an 8mm line. Each connector is labeled by size and profile so you can select the correct adapter for the hose diameter and desired routing angle.

• 90° elbow options: 5/16" (7.89mm)×8mm, 3/8" (9.49mm)×8mm, 9.89mm×8mm
• Straight couplers with the same three SAE-to-8mm conversions
• Pipe-style straight fittings for direct inline joins between SAE and 8mm
• Total count: 6×90° + 6×straight + 12×pipe fittings = 24 pieces

Are these connectors compatible with fuel and other fluids?

The connectors use materials chosen for contact with gasoline, diesel, ethanol blends and many common automotive fluids. FKM (fluoroelastomer) O-rings maintain sealing performance with aggressive fuels like E85 and resist swelling or deterioration with oil and solvent exposure.

• FKM O-rings rated for ethanol, methanol, E85, and diesel
• Body materials designed for fuel resistance and durability
• Suitable for fuel, oil, coolant (where materials match), and many workshop fluids

How will this kit make installation and repairs faster?

Quick-connect geometry and the selection of elbows and straight styles let you make clean transitions without cutting custom reducers or fabricating adapters. The varied sizes reduce downtime because you can try the correct fit on the spot rather than sourcing individual parts.

• Pre-sized SAE-to-8mm parts eliminate need for custom hose splicing
• 90° elbows help route lines around tight engine bays or components
• Durable construction suited for repeated install/removal cycles

What should I check before using these connectors?

Confirm hose inner diameters and verify the SAE size to ensure a proper interference fit. Inspect O-rings for damage and replace if nicked; always clamp lines where required by the application and pressure rating of the system.

• Measure hose ID to match 7.89mm, 9.49mm, or 9.89mm options
• Replace O-rings if worn; ensure correct orientation during assembly
• Use appropriate hose clamps when system pressure or vibration requires them

Who is this for: Technicians, DIY mechanics, small-fleet maintainers, marine hobbyists, and anyone who services carbureted engines, performance fuel systems, or mixed-diameter plumbing will find this AC PERFORMANCE 24-piece kit useful. It’s intended for non-pressurized to typical automotive fuel line applications where quick, fuel-compatible transitions are needed; choose connectors and secure clamps according to your system’s pressure and safety requirements.
