Fuel Line USCG Type for Under RIB Floor

[Terrapin]

I am moving my fuel tank to the bow locker on my Highfield Classic 290 Hypalon RIB. Is USCG Type B1-15 hose acceptable for the entire run from the bow gas tank to the engine, or is USCG Type A1-15 required under the floor from the bow gas tank to the water filter separator on the transom?

B1 is only for spaces that aren't enclosed where as A1 is rated for enclosed spaces. Why not just get the hose that you can use anywhere on the boat?

I personally would use A1

OK thanks, I will go with the A1 since I don't know whether I would comply with fuel discharge section (b) (2) (ii) of 183.558.
Any experience with flexibility of the Trident Marine A1-15 Part Number 365-0560 ?
