Big fan of Trident. Replaced all my fuel lines from separator to primer bulb to fuel pump with Trident A1 last week.
Bear in mind that A1 is designed for use in an enclosed area. It has a thick, fireproof cover and comes in a couple of different configurations ( bend radius). Check to make sure the bend radius matches your needs.
Hose type B1 is not fireproof and only approved for use above deck in open air. Typically used between the primer bulb and fuel pump. The infamous “grey” hose is is rated for B1 applications
