not sure if the Frontiers and Pathfinders uses the same part for the gas door.
but on the 05 Paths, its a "w" shape spring and holds the door open or shut.
I've only filled up a couple of times and I think like the 4th time, the stupid clip popped out.
I thinks its a bad design.
when I go back to the dealer I will let them know and maybe they can fix it. its okay now, but just not as affective as I would like it to be.
also, the cap holder doesnt work. the gas cap doesnt even fit in that holder and with the cable, it just gets in the way.
just complaining about these small things
I just like the way its works on my 92 Integra. SIMPLE.
