3/8 in (10mm) ID Fuel Line Hose — 10 FT 300 PSI Push Lock NBR Rubber Hose for Automotive
Product description
If you need a fuel line that’s built for real-world automotive fluids, this 3/8 in (10mm) ID hose checks a lot of practical boxes. The pitch here is simple: NBR rubber construction, oil resistance, and a defined working/burst pressure range—so you’re not guessing when it comes to reliability under load.
That said, it’s not a universal “fit everything” solution. It’s designed to work with hose barbs and fuel line clamps, and you’ll want to confirm your application pressure before buying. If you do that basic homework, it can make a straightforward upgrade or replacement feel much less stressful.
The essentials (what it is and what it’s for)
This is a 3/8 inch (10mm) inside-diameter fuel line hose, sold as a 10-foot length. The material is NBR rubber, called out as oil resistant. The product positioning is for conveying automotive fluids such as gasoline, diesel, biodiesel, engine oil, and even water (depending on your setup).
On the spec side, the hose is stated as AN6 fuel hose (with OD listed as 5/8 inch / 16mm). It’s also labeled with a working pressure of 0.6Mpa and a burst pressure of 1.8Mpa, plus a temperature range from -40°F to 248°F. Over the board, that’s the kind of information that helps you judge “will it hold up?” rather than treating it like a generic piece of rubber.
In everyday use, think of it like this: you’re swapping a worn section of fuel line on a vehicle (or similar automotive application), you route it along the chassis, then secure it at each end with clamps over hose barbs. Done right, it’s the unglamorous part that keeps the system doing its job.
Key points (what stands out in real buying)
The biggest strength here is clarity: the hose size (3/8 in ID), the length (10 FT), the stated pressure ratings, and the temperature window are all provided. For buyers, that means fewer “maybe it’ll work” decisions.
Another strong point is the material choice. NBR is explicitly framed as oil resistant, which lines up with why people shop for fuel/oil lines in the first place. If your current line is hard, swollen, or showing wear, a hose like this is the kind of replacement that can bring the system back to a safer baseline.
Where it gets a bit less comfortable: it’s not described as a ready-to-mount assembly with fittings. You’ll be using hose barbs and fuel line clamps for installation. If your project needs specific end connections that aren’t covered by barbs/clamps, you may need extra parts—or you might choose a different style of hose kit.
Quick overview of specs that matter
Here are the practical specs called out in the listing so you can sanity-check fit and stress:
Tech specs
- Size: 3/8 inch (10mm) ID
- Outside diameter: 5/8 inch (16mm)
- Length: 10 FT
- Type/label: AN6 fuel hose
- Material: NBR rubber (oil resistant)
- Working pressure: 0.6Mpa
- Burst pressure: 1.8Mpa
- Temperature range: -40°F to 248°F
Pros
- NBR rubber is specifically described as oil resistant, which matches typical fuel line use.
- Pressure and temperature ranges are provided, so you can evaluate risk instead of guessing.
- Straightforward sizing: 3/8 in ID with OD and 10-foot length listed.
- It’s positioned for multiple automotive fluids like gasoline, diesel, biodiesel, and engine oil.
What to watch out for before you buy
This is where a lot of fuel-line purchases go wrong—not in the hose itself, but in the assumptions.
First, the listing explicitly says to check the pressure of your application before purchasing. If your system pressure sits close to or above what the hose is rated for (working pressure in particular), you don’t want to gamble.
Second, confirm compatibility with your install method. The instructions say to use hose barbs and fuel line clamps. If you were hoping for a push-on hose with included fittings that doesn’t require barbs/clamps, keep in mind this description doesn’t promise that.
Third, the temperature range (-40°F to 248°F) helps, but routing matters too. Even a well-rated hose can wear faster if it’s kinked, rubbed against sharp edges, or installed where it’s constantly overheated.
Who it makes sense for (and who should skip it)
It’s a solid pick if you’re doing a fuel line replacement or fluid transfer setup in an automotive context and you can match the hose size (3/8 in ID) with the right barbs and clamps. It suits buyers who want the basics—correct diameter, oil-resistant material, and clear pressure/temperature specs.
It might not be a great match if you need a specific end fitting style that isn’t compatible with hose barbs/clamps, or if you’re not sure about your system pressure and don’t plan to verify it. Also, if your goal is a plug-and-play install with fittings included, this one could feel a little “DIY dependent” based on what’s stated.
Final verdict
Worth considering if you need a 3/8 in (10mm) ID NBR rubber fuel line in a 10-foot roll and you’re comfortable installing it with hose barbs and fuel line clamps. The stated working/burst pressure and temperature range make it easier to judge fit for your application.
You may want to skip it if you can’t confidently check your application pressure or if your project requires a specific connector style that isn’t addressed in the listing. For most straightforward automotive fuel-line replacement jobs, it looks like a practical, mid-range kind of solution—useful when you verify pressure and installation compatibility.
