What we do

We sell one narrow thing, and we sell it properly: hose for small engines. Fuel line for the machines that run on gasoline, and silicone hose for the systems that move air, vacuum and coolant. That is the whole catalogue.

We are deliberately not a general hardware store. Narrow means we can tell you the exact inside diameter your mower takes without looking it up, and it means the answer you get from us is the same answer whether you asked by email at 9am or found it in a product table at midnight.

Why the sizes matter so much

Most people who order the wrong hose order it because fuel line gets sold by outside diameter — the number that is easy to measure and the one that tells you nothing. What actually matters is the inside diameter, because that is what has to pass fuel at the rate your engine needs.

So everything on this site is organised around inside diameter: the product tables, the size chart, the machine pages and the kits. If you tell us your machine, we will tell you the number. That is the whole idea behind the name.

The two product lines, and the rule between them

These two hoses look similar and are absolutely not interchangeable:

• Black rubber (NBR) line — made for gasoline and oil. This is the fuel system line.
• Silicone line — made for air, vacuum, coolant and water. It must never see fuel.

Silicone swells and breaks down when it meets petrol or diesel. A failed fuel line next to a hot engine is a fire risk, not an inconvenience. That is why the silicone products carry a red warning, why the two lines are kept apart in the shop, and why we will ask you what you are connecting before we recommend a hose.

How we ship and support

• Shipped from our own US warehouse. Nothing is drop-shipped from overseas, so there is no customs step and no three-week wait.
• Dispatched in 3–5 business days, with tracking emailed when the carrier scans the parcel.
• 30-day returns on unused, uncut hose. No restocking fee.
• A person answers. Not a ticket queue, not a chatbot. Sizing questions usually take one reply.

What we will not do

• We will not sell you a hose size we are not confident about. If we do not know your machine, we will say so and ask for the measurement.
• We will not point you at silicone for a fuel job, whatever the price difference looks like.
• We will not dress up a wear item as a forever part. Fuel line is meant to be replaced, and we will tell you how often.
