8mm (5/16") Fuel Hose Automotive SAE30R7

8mm (5/16") SAE 30R7 fuel hose is one of the two most ordered fuel hose sizes, and the standard bore for carburettor and low pressure injection feeds on cars, light commercials and small plant. The nitrile rubber tube is compounded to resist diesel, oil and unleaded petrol including ethanol and methanol blends, and the cover withstands fuel, vapour, moisture and heat to 100°C.

Key features

• Nominal inside diameter 8 mm, outside diameter 14 mm
• Working pressure 50 psi (3.4 bar) at 20°C
• Operating temperature -20°C to +100°C
• Meets and exceeds SAE J30R6 and SAE J30R7
• Black nitrile rubber blend tube, compounded for petrol, diesel and ethanol blends
• High tensile synthetic braid reinforcement
• Black smooth synthetic rubber cover, weather and ozone resistant
• Cut to length or supplied on spools (152.4 m and 200 m)

Applications

• Automotive carburettor fuel lines
• Low pressure fuel feed and return
• Diesel lift pump lines
• Marine and outboard fuel systems
• Generator and small plant fuel lines

Compatibility and fitting

• Sized on inside diameter: 8mm hose fits a 8mm barb or spigot
• Clamp with a smooth band or fuel rated hose clamp; a perforated band can cut a fuel line over time
• This is a low pressure hose. Do not use it after a high pressure injection pump
• Do not substitute general purpose rubber multi purpose hose, which is not rated for fuel

Is this suitable for fuel injection?

Only low pressure fuel systems. SAE 30R7 is rated to 50 psi, and a modern high pressure injection line runs far above that. Use a hose rated for injection pressure on anything after the high pressure pump.

Sizes from 5 mm to 12 mm are in the automotive fuel hose range.
