What does the fuel line filter of a 1991 ford ecoline van look like and located?
It is round, usually metal, and you can palm it in one hand. It is located underneath the vehicle usually on the driver side frame rail, along the brake lines usually about a third of the length of the vehicle from the front. These more frequently require a special tool to release fuel lines, available at most auto supply stores about $10.00.
The filter is located inside the vehicle frame almost directly under the drivers seat of the vehicle. It is about the same size of a beer can. One needs a special tool to loosen the fuel lines from either side of the filter. Tool can be bought at most auto parts stores. BE CAREFUL AS THE FUEL SYSTEM IS PRESSURIZED!!!!!
