2003 Ford Focus fuel

The other day I put a new gas filter on my sisters focus. And while I was underneath it I seen a couple of the charcoal canister hoses kind of in a kink, so I remover the retainers clips and fixed the kinks.I couldn't use the original ones so I put some in vary close, I will be putting the correct ones in as soon as I get to a dealership, so my sister was telling me that the other day she had over a half tank, and she did a little driving but not a whole lot, and it went down to a 1/4 quick it is not leaking any gas so I don't know.
