Your fuel filter is located beneath the passenger side...
It could be the clamps on the ends of the filter cos sometimes they are replaced with cheap clamps which tend to rust easily,there is also a join so to say just after the filter where the rubber pipe meets a metal pipe,the rubber tends to get brittle and wear out a bit at the clamped end...
I had the similar probs on my car costed me around 30 bucks for new piping and clamps and took me like 15min to do...
Hope this helps
