The fuel filter filters out particulate matter that may damage your 1977 Buick Regal as the fuel passes through it. It is a small component in the engine that is inexpensive, only $10 to $20, but it can save you thousands in repair costs if changed frequently (every two to four months). The fuel filter is a simple piece to change by the at-home mechanic.
