I agree with carringb, the fuel pump could be a concern and it might be worth replacing as a pm rather than waiting until it fails. I've had three fuel pumps fail (I tend to hold onto my vehicles), and to be honest, with the exception of one of them, I had no warning they were on their way out. The one that did give a warning, only started to do so on the drive home, which was 50 miles. The pump failed as I was driving through an intersection.
As pointed out, changing the pump typically involves dropping the tank. This is a job best left to a professional, as you should use non sparking tools. One spark, and it's all over!
