Where is the gas filter located on a 1993 Ford E-150 van?
On the inside of the driver side frame rail just ahead of the gas tank. You need a special tool (available from a parts store) to remove the filter. The tool helps to release the filter from the fuel line fitting. Sometimes it's easy to remove and other times it's difficult. I've been there.
