The BMW E30 3-Series fuel filter should be replaced about every 10,000 miles. This is a relatively easy maintenance task that can be done at home. The fuel filter is responsible for filtering out small impurities such as dirt and rust that accumulate in the fuel tank over time. When the filter gets clogged, it can cause the car to run sluggishly or not at all. To replace the fuel filter, you will need to loosen the hose clamps on either end of the filter, remove the old filter and hoses, and install a new filter and hoses.
