1 Metre of 6.5 x 14 fuel pipe which is ideal for Vespa and Lambretta scooters.
WHY IS THIS FOR VESPAS AND LAMBRETTAS?
The fuel pipe size referred to as 6.5 x 14 mm is a common specification for Lambretta and Vespa scooters, where 6.5 mm is the inner diameter (ID) and 14 mm is the outer diameter (OD). This specific dimension is used for several practical and performance reasons:
- Optimal Fuel Flow: The 6.5 mm inner diameter is considered ideal for both standard and tuned engines, especially those with larger carburettors (such as Dellorto VHSB/VHSH and Mikuni TMX types), as the wider bore helps ensure a sufficient and uninterrupted flow of fuel, preventing potential starvation issues.
- Kink Resistance: The generous 14 mm outer diameter results in a thick wall. This heavy-wall construction provides excellent resistance to kinking or collapsing when bent, even in the tight confines of a scooter frame. This is a significant advantage over thinner-walled pipes (e.g., 6x9mm) which can easily kink and restrict fuel flow.
- Durability and Heat Resistance: The thick outer wall also helps the pipe cope with varying temperatures (heat and cold) and makes it more durable and abrasion-resistant.
- Secure Sealing: The substantial outer diameter helps the pipe form a perfect and secure seal when routed through the frame grommets and connected to the fuel tap and carburettor spouts, reducing the risk of leaks.
- Ethanol Resistance: Modern, high-quality pipes of this size are often made from advanced materials (like Tpr-Pur or dual-core formulations) that are resistant to the corrosive effects of ethanol found in modern E5 and E10 petrol. This ensures the pipe remains soft and supple, and does not harden, shrink, or perish over time, which is a common problem with traditional fuel lines.
In summary, the 6.5 x 14 mm pipe is a reinforced, durable, and flow-efficient solution designed to meet the specific requirements and overcome common problems associated with the fuel systems of classic Lambretta and Vespa scooters, particularly when dealing with modern fuels and engine upgrades.
