Fuel Filter Location
Caution: When replacing fuel filters keep in mind that the old filter contains a considerable amount of fuel that will need to be safely handled and disposed of. Also keep in mind that most systems will have some residual pressure in the lines. Have plenty of old rags available to catch any fuel that spills.
