The fuel filter for your van is located on the passenger side, just underneath the rail, near the back tire.
On my Prospector the fuel filter is located under the hood near the right tire.
It is not a user-servicable fuel filter. It is located in the gas tank.
It is above the inboard edge of the fuel tank.
The fuel filter is part of the fuel pump module and is not serviced separately.
may be in fuel tank
On my 91 it is under the van on the inside of the frame
Your fuel filter is actually a "fuel sock" attached to the bottom of the in-tank fuel pump.
right below the alternator , follow the fuel lines off of the frame.
They tell me it is in the fuel tank. Like another answer, drop the tank to get to it.
The filter is in the gas tank, in with the fuel pump.
it is run along the inboard side of the fuel tank
