Bass Cat can provide A1 fuel lines, which should be what is in your boat and they should not require replacement. We’ve used A1 or A2 on the boat side for four decades, as the cost is minimal, the value of quality in long term ownership is important. It’s been that way ever since ethanol resistant lines were available.
The engine lines will not be ethanol resistant and will require replacement. Ethanol resistant fuel bulbs and engine lines didn’t happen until 2012.
