1995 Chevy Astro filters

The fuel filter should be under the vehicle, driver side, below seating area, front of fuel tank, mounted on chassis in fuel line

is that the only filter for fuel

yes, what is the problem you are having?

my van is sputtering. like a filter is clogged up. like water is in my tank

have you already replaced said filter? also try fuel treatment with the next fill up. also check the spark plugs, it could be a spark issue
