Fuel hose ID and supplier

[David G]

Afternoon All,
I'm after some advice on recommended Internal Diameter for replacement fuel hose and a supplier of it!
The engine is an early 1990s Suzuki DT85.
How much should this cost per metre?
Thanks in advance.

Most marine places sell it. We only now sell the ISO flame retardant stuff as it outlasts everything else. Be careful of the cheap stuff as the inner liner has a habit of collapsing and blocking the line. But cheap buy twice or maybe three times!
