Does anyone know what the difference is between a fuel vent hose that is rated SAE J1527 A2 vs SAE J1527 B2? I am going to redo the vent line on my tank to fix the problem that MC should have done from the beginning instead of giving me you need to fill the tank with an eye dropper as the solution to gas pouring out the vent while filling. The current vent line is rated as A2 and I can get B2 at about half the price. Both are rated for marine vent lines, but there has to be a difference.
