EVIL ENERGY 3/8" NBR Fuel Hose 25FT — SAE 30R7, 300 PSI Working Pressure, Braided Reinforced

EVIL ENERGY 3/8" NBR fuel hose is a 25-foot, SAE 30R7–compliant push-lock line built from NBR and braided polyester for reliable fuel, oil, and biodiesel delivery at up to 300 PSI.

This 3/8" (9.5 mm ID) fuel hose delivers a rugged, flexible solution for fuel-system plumbing, oil cooling lines, and general liquid transfer where SAE 30R7 compatibility is required. Rated for a wide temperature span and high burst pressure, it balances chemical resistance with abrasion durability for workshop, marine, and mobile equipment applications. The following sections answer common buyer questions and highlight specific details to help you confirm fit and performance.

What are the key dimensions and pressure ratings?

The hose has a 3/8" (9.5 mm) inner diameter and an outer diameter of 2/3" (17 mm), with a wall thickness of 3 mm. It is designed for a working pressure of 300 PSI and a burst pressure of approximately 1,200 PSI.

• Inner diameter: 3/8" (9.5 mm)
• Outer diameter: 2/3" (17 mm)
• Wall thickness: 3 mm
• Working pressure: 300 PSI; burst: 1,200 PSI

Which fluids and environments is this hose compatible with?

Constructed from nitrile rubber (NBR) with a braided polyester reinforcement, the hose resists oils and many hydrocarbons, making it suitable for diesel, gasoline, biodiesel, oil, and grease. Its material choice gives good chemical compatibility without sacrificing abrasion resistance.

• Compatible with diesel, gasoline, biodiesel, oil, and grease
• NBR rubber resists petroleum-based fluids
• Braided fiber improves kink resistance and mechanical strength

How does the hose perform in different temperatures and installation conditions?

The EVIL ENERGY hose operates over a broad temperature range from -40°F to 257°F, suitable for cold starts and elevated-engine temperatures. Its 3.9" (100 mm) minimum bend radius supports compact routing while maintaining flow and longevity when installed correctly.

• Temperature range: -40°F to 257°F
• Minimum bend radius: 3.9" (100 mm)
• Flexible enough for tight routing, yet reinforced for pressure stability

Where and how is this hose typically used?

This SAE 30R7-rated line is intended for fuel-system plumbing, oil cooling circuits, steam emission lines in compatible setups, and general-purpose transfer of petroleum fluids in automotive, industrial, and marine contexts. It meets or exceeds the SAE 30R7 standard for such applications.

• Fuel lines and return lines on engines and generators
• Oil cooling and lubrication supply circuits
• General fuel-transfer and workshop hose applications

Who is this for? Installers, mechanics, fleet maintenance teams, and DIYers who need a dependable, SAE 30R7–compatible fuel hose will find this EVIL ENERGY 3/8" NBR line suited for moderate-pressure fuel and oil systems. Choose this 25-foot roll when you require chemical resistance to petroleum products, a wide operating temperature range, and a compact bend profile for tight engine bays. Avoid using this hose for high-pressure injection systems or fluids outside its chemical compatibility list.
