Gates Fuel/Vacuum Hose 25 ft, 3/8" ID — SAE J30R7 Spiral-Reinforced, Fuel-Resistant

Gates 27004 is a 25-foot, 3/8" inner-diameter multi-purpose fuel and vacuum hose engineered for return fuel lines, PCV and EEC systems, and diesel fuel return applications.

This hose is built to handle modern fuel blends and harsh under-hood conditions while remaining a convenient, reusable length for repairs and installations. Its tube and cover materials are formulated to resist heat, oil, ozone, and weathering, and the spiral reinforcement gives the hose the crush resistance and dimensional stability required for fuel-return and vacuum routing. Approved for use with leaded and unleaded gasoline, diesel, and common oxygenated fuels (including ethanol blends up to legal limits), the Gates 27004 is specified to meet SAE J30R7 and DIN 73379 requirements for automotive fuel and vacuum tubing.

How does this hose stand up to modern fuel blends and chemicals?

The inner tube has been upgraded to tolerate contemporary fuel formulations and oxygenates without premature softening or breakdown. While not a chemical-immersion product, it resists the common fuels and additives you’ll find in automotive and light diesel service.

• Compatible with leaded/unleaded gasoline and diesel
• Rated for ethanol blends (E85), methanol and ethers within EPA limits
• Tube chemistry optimized for fuel resistance and service life

Will this hose cope with heat, oil, and outdoor exposure?

The outer cover is formulated to resist heat, oil contamination, ozone attack and general weathering, making it suitable for under-hood routing and occasional exterior exposure. That resilience helps preserve flexibility and appearance over time.

• Cover resists heat and oil to reduce cracking and swelling
• Ozone- and weather-resistant coating for durability
• Maintains flexibility across typical engine bay temperatures

How strong and easy to install is the Gates 27004 hose?

Spiral reinforcement gives the hose structural stability against collapse and kinking while keeping it pliable enough for routing. Supplied in a 25-foot length, it’s convenient for trimming to fit custom runs, and the packaging is reusable and display-ready for retail environments.

• Spiral-reinforced construction prevents collapse under vacuum
• 25-foot continuous length for multiple repairs or long runs
• Reusable, recyclable package fits pegboard display

Does it meet industry standards and which systems is it appropriate for?

Gates 27004 meets applicable performance requirements of SAE J30R7 and DIN 73379 (except tolerances), making it suitable for fuel return lines, PCV/EEC vacuum systems, and diesel fuel return connections. It’s not intended for pressurized high-pressure common-rail feed lines.

• Complies with SAE J30R7 and DIN 73379 specifications
• Designed for return fuel lines, PCV, EEC and diesel return hoses
• Not for high-pressure fuel injection feed lines

Who this is for: Technicians, home mechanics, and fleet maintenance personnel who need a reliable, fuel-resistant hose for return lines and vacuum systems will find the Gates 27004 ideal. It’s especially useful when you want a durable, long-length supply that withstands modern fuels, engine heat, and routine exposure to oils and ozone. Choose this hose when you require a compliant, service-grade solution for routing fuel return, PCV or EEC vacuum lines in gasoline or diesel applications.
