What spec of flexible fuel hose should I ask for

[ChrisKaye]

Just writing back to the vendor after the survey. Flexible hoses have perished. What specification of flexible fuel hose (diesel) should I ask for fitting in the engine bay of proposed boat purchase.

 

[Salty John]

ISO7840 A1 is the current standard. I believe.

Current Boat Safety Reg below, might help even on your on the coast.

2.10.2/R REQUIREMENT
Are all flexible fuel feed and return hoses suitable for the fuel used
and fire resistant?
Check the marking on all fuel feed and return hoses.
Fuel feed and return hoses must be marked, to denote both
suitability for the fuel used and fire resistance, to BS EN ISO 7840
or an equivalent standard.
Notes – Hoses marked to SAE J 1527 and DIN 4798 are acceptable.
Armoured or other external braiding is not evidence of hose suitability
or fire resistance. Such hoses must be marked as above.
Where a hose is not marked as meeting an accepted standard but its
suitability is claimed, evidence should be sent to the BSS Office for
consideration of the claim.
Fuel hose suitability may be supported by a written declaration from
the hose manufacturer or supplier or, if appropriate, from the engine
manufacturer/supplier or mariniser.
