I was going to change the fuel filter and it's not even listed at the parts store, is it dealer only or something?

The filter may be part of fuel pump assembly.

Fuel filters on these vans are not meant to be changed for maintenance reasons. Only do it if you have a problem. Chances are you'll break the fuel lines off the sending unit if you do. The filter is on top of the gas tank and it has to be lowered to access it.
