.. depending on where you are in the world, and layout at site.
But is your hose actually compatible allowed and recommended for this type of fluid?
Else:
Mechanical, and equipment bound norms and rules.
Onboard ship rules.
Safety rules for handling the fuel as hazardous fluid, including toxic and flammabletotal and in given pipeline
Local and environmental rules...
And possibly quite a few others....
From 'outside' it would probably be near impossible to give and exact answer. For advice: producer or supplier of hose and fluid and local authorities.
On the other hand: fuel is pumped every day, althoug I believe, not very much in lay-flat hoses (?)....
