I replaced my filler port with one like Jenn has, it has a cap that seals tight and should be easier to fill when using a water jug.
Iamjudy, I don't think that the spring tension is adjustable, the rubber "springs" are probably just getting a little tired. Maybe, you could have a spacer put in between the axle and frame.
