Yes, the balancer may be coming apart. Check the rubber between the two pieces to see if it has shifted. Also see if the belt is aligned with all the pulleys

Do you have the defrost on when it is doing this? Turn it off and see if it goes away. I'm still thinking A/C compressor.

the fuel filter is located inside the frame rail on the passenger side, sort of underneath the rear seat. there are two plastic lines on either side with quick release fittings. i believe its held on my a gear clamp style holder. not too difficult to change.

it should be located near the battery itself on the negative terminal cable
