Frequently Asked Questions (FAQ)

❓ Is this hose ethanol-safe?

Yes – it is rated safe for unleaded and E10 petrol. Not recommended for E85 or alcohol-based fuels.

❓ Can I use it for diesel?

Absolutely. It is suitable for standard automotive diesel (up to 7% biodiesel content). Not for pure biodiesel (B100).

❓ Is this made in Europe?

Yes – manufactured in a Danfoss-owned ISO facility in the EU and sourced from Germany.

❓ Can I use it inside a fuel tank?

No. This hose is not designed for submersion. Use SAE 30R10 hose for in-tank installations.

❓ What size hose do I need?

Check the outer diameter of your fittings. Common barbs are 1/4" (6mm), 5/16" (8mm), and 3/8" (10mm).

❓ Can I return the hose?

Yes – returns are accepted if the hose is unused, uncut, and in resellable condition.

❓ What are AN sizes and how do they relate to this hose?

"AN" stands for Army-Navy and is a hose sizing system used primarily in motorsport and performance builds. Each AN size equals 1/16" increments in outer diameter. This hose is sold by metric inner diameter (ID), but aligns with common AN sizes as follows:

5mm ≈ AN3 – Small fuel lines, vents, vacuum/boost applications
6mm ≈ AN4 – Carburetors, motorcycles, emissions plumbing
8mm ≈ AN6 – EFI return lines, catch cans, general fuel use
10mm ≈ AN6 / AN8 – Main fuel feeds, V8s, brake booster lines

For best results, match the hose ID to the outer diameter of your barb or push-on fitting and secure with quality clamps.
