Rubber Braided Fuel Hose — Reliable Petrol, Diesel & Oil Line Routing in Any Size
Routing fuel or oil lines in a tight engine bay, fabricating a custom fuel system, or replacing a cracked hose on a generator or small engine? Finding a rubber braided fuel hose that fits your exact barb size — without ordering a full reel — is a constant frustration for mechanics, fabricators, and serious DIYers alike. This hose is sold by the meter in 16 inner diameter sizes, so you get exactly what you need without waste.
Each meter of hose features a rubber inner tube reinforced with a textile braid layer, providing flexibility while resisting fuel permeation and pressure. Inner diameters range from 4mm (≈5/32") to 40mm (≈1-9/16"), covering the most common barb fitting sizes used in automotive, marine, and small-engine fuel systems. Wall thickness varies by diameter — contact us to confirm OD for your specific size.
Typical applications include low-pressure fuel feed and return lines on carbureted engines, diesel gravity-feed systems, oil drain and breather lines, and general-purpose fluid transfer in workshop equipment. The flexible construction makes it easy to route around obstacles without kinking, and it accepts standard hose clamps for a secure, leak-resistant connection.
ℹ️
Compatibility: Designed for unleaded petrol (gasoline), diesel fuel, and lubricating oil lines. Not recommended for ethanol blends above E10, brake fluid, or coolant without confirming chemical compatibility. Sold per 1-meter length — select your inner diameter above.
✅ Key Features of These Rubber Braided Fuel Hose Lines
-
⛽Fuel & Oil Resistant Inner Tube — The rubber bore is formulated to resist degradation from unleaded petrol, diesel, and lubricating oil, helping maintain flow integrity over time in automotive and small-engine fuel line applications.
-
🧵Textile Braid Reinforcement — A woven braid layer between the inner tube and outer cover adds dimensional stability and pressure resistance, reducing the risk of ballooning or collapse under low-to-medium system pressures.
-
📏16 Inner Diameter Options (4mm–40mm) — Available in sizes from 4mm (≈5/32") to 40mm (≈1-9/16"), covering the full range of common barb fittings used in carbureted engines, diesel systems, marine fuel lines, and workshop equipment.
-
✂️Sold by the Meter — Cut to Fit — Each unit is one continuous meter of hose, letting you cut exactly the length you need for custom fuel line routing without paying for excess material or dealing with minimum reel quantities.
-
🔧Flexible & Kink-Resistant Construction — The layered rubber and braid construction maintains flexibility across a range of temperatures, making it easier to route around engine components, frame rails, and tight bends without kinking or restricting flow.
-
🔩Standard Hose Clamp Compatible — Works with widely available stainless steel worm-drive hose clamps for a secure, leak-resistant seal on barb fittings — no special tools or proprietary connectors required.

❓ Frequently Asked Questions
How do I choose the right inner diameter for my fuel line?
Measure the outer diameter of the fitting or barb the hose will connect to — the hose ID should match that dimension for a snug, leak-free fit. For example, a 6mm (≈1/4") barb fitting typically requires a 6mm ID hose. When in doubt, size down slightly so the hose stretches over the barb and grips securely. If you're replacing an existing hose, measure the old hose's bore with calipers for the most accurate match.
What pressure can this braided rubber fuel hose handle?
Braided rubber fuel hoses of this construction are generally rated for low-to-medium pressure applications — typically up to 150 PSI depending on diameter and wall thickness. They are not intended for high-pressure fuel injection systems (which typically require 60–100+ PSI rated injection-grade hose). Contact us to confirm the pressure rating for your specific size before use in pressurized systems.
Can this hose be used outdoors or in engine bays?
Yes. The rubber compound used in braided fuel hoses is generally resistant to heat, ozone, and UV exposure, making it suitable for engine bay routing and outdoor installations. For sustained high-heat environments (above approximately 100°C / 212°F), verify the specific hose rating before use. Avoid routing directly against exhaust components without heat shielding.
Is this hose compatible with unleaded petrol, diesel, and oil?
Yes. This hose is designed for use with unleaded petrol (gasoline), diesel fuel, and lubricating oil lines. It is not recommended for use with ethanol blends above E10, brake fluid, or coolant without confirming chemical compatibility first. If you're working with alternative fuels or specialty fluids, contact us before ordering.
How do I cut the hose to length and secure it to fittings?
Use a sharp utility knife or dedicated hose cutter for a clean, square cut — this ensures a proper seal against the barb. Secure to barb fittings with stainless steel worm-drive hose clamps for a reliable, leak-free connection. Avoid over-tightening clamps on smaller diameters (4mm–8mm) to prevent cutting into the hose wall. Position clamps approximately 5–10mm from the end of the fitting for best grip.
What is the difference between inner diameter (ID) and outer diameter (OD)?
Inner diameter (ID) is the measurement of the hollow bore — the dimension that determines flow capacity and fitting compatibility. Outer diameter (OD) is the full width of the hose including the rubber wall and braid layer. Always select hose by ID to match your fittings. The OD will be larger than the ID and varies by size; contact us to confirm the OD for your chosen variant if you need to route through a grommet or bracket with a specific clearance hole.
Can I use this hose for hydraulic systems?
This hose is generally suitable for low-pressure hydraulic oil lines in automotive and light industrial applications — for example, oil breather lines, gravity-feed oil systems, and low-pressure return lines. For high-pressure hydraulic circuits (typically above 150 PSI), a purpose-built hydraulic hose with a certified burst pressure rating is recommended. Contact us if you're unsure whether this hose suits your hydraulic application.
